I am having Windows 11 and Ubuntu 22.04 LTS dual boot system. Windows 11 on regular SSD while Ubuntu 22.04 LTS on PCIE NVME SSD. It's Dell XPS 8930 Desktop(2018) where I have made a lot of upgrades and additions. As part of the latest upgrade, I upgraded 512GB PCIE NVME SSD(version 1) to 4 TB PCIE NVME SSD(ver 4.0). I used AOMEI cloning software for this . In the process of upgrading PCIE NVME SSD, I removed the swap partition as it was not being used any more. Disk cloning was successful. After that I just swapped the old PCIE NVME SSD with new PCIE NVME SSD in the desktop.

Dual boot - windows and Linux all booted properly. But the only issue is this check that is there. In the past also I had this check but it was a smaller PCIE NVME SSD but now it is for larger PCIE NVME SSD.

Message is as follows: SGX Launch Control is locked. Support SGX virtualization only. I believe this might be due to the fact that I have enabled virtualization in the BIOS. This message is quick. But after that it's sort of check disk kind of process. Mine PCIE NVME SSD(on which Ubuntu 22.04 LTS is installed is 4TB) so this check disk kind of check is really slowing down the boot process. How I can disable this checkdisk kind of process.

Tried this approach also but no success. Tried this approach also but no success. Here is the video of this issue

I think this could be the potential issue

I have a dual boot system - Windows 11 and Ubuntu 22.04 LTS. Windows 11 on regular SSD(2.5 inches) and Ubuntu 22.04 LTS on PCIe NVME Gen 1 - 512 GB. As PCIE NVME prices has come down and my usage of linux has increased, I bought another PCIe NVME Gen4 4 TB drive for my linux. My desktop's mother board has provision for only one PCIe NVME drive which means I need to clone 512 GB PCIe NVME to 4 TB PCIe NVME. Has somebody has done this in the past? Anything to be taken care of? My linux install is simple - / and swap partition and nothing fancy. Was going thru this link but it seems there is not much discussed about this.

I followed this to remove Ubuntu 20.4.1 LTS and grub2 - the answer with the most upvotes. After that grub2 black screen is gone but Windows 10 is not booting.

Update1

I logged in using live USB and then tried boot-repair. Followed all the recommendations by it. It tried to reinstall grub2 so there seems to be another Ubuntu Linux 20.4 some where being installed on my computer(I have 1 NVME PCIe drive where Ubuntu Linux was installed - which i deleted, then 1 SSD where Windows is installed i.e. Windows C drive and then two hard drives for Windows D and E). It seems somewhere on C, D or E - ubuntu linux is installed and i want to get rid of it OR move to PCIe NVME drive Here is the boot-repair output link and contents from boot-repair activity:

You can now reboot your computer.

Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.1 LTS entry (sdb2/EFI/ubuntu/shimx64.efi file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

Here is the gparted view from my Ubuntu Linux 20.4 LTS

There is somehow hidden Ubuntu 20.4 LTS being installed some where else also which is making my grub to boot into Ubuntu 20.4 LTS Linux.

Update 2 After some more searching and digging, found that another copy of Ubuntu Linxu 20.4.1 LTS is installed on /dev/sda7

and also confirmed by df command

Update 3 Even after deleting /dev/sda7 partition from Windows and then deleting /EFI/ubuntu - i was not able to make Windows 10 boot. Thus used the live USB drive to copy the important data from Windows C: into Windows D: Later used the Windows recovery drive to reinstall the Windows on C: drive. I could have installed it on other drive but my C: is SSD and i prefer installing OS and apps on faster media.

I had this issue in the past. After the BIOS update, 20.04LTS is loading up(though slowly)-but no internet connection(even when i am using Ethernet cable and it works fine in Windows 10-so no hardware issue). Graphics driver is also not loaded. Yes, I am talking about multiple issues but i want to focus only on networking right now. I cannot login to 18.04 LTS strangely.

Tried this and this but no luck

Output of ip a or ifconfig

Output of lspci -knn | grep Eth -A3

Output of sudo dmidecode -s bios-version

Update1

Finally I got fed up of login into ubuntu linux - try out one command after the other, take the snapshot from phone and then post it here to go no where. Decided to install Ubuntu Linux all over again. Install detected 20.4 LTS already and gave me the option to install 20.4.1 LTS along side it. Tried that option but it also messed up. Was getting the black grub 2 screen and nothing else. Tried boot-repair from live USB and it's back.

Better to always install fresh rather than upgrade or rely on others suggestions.

I had successfully running Windows 10 and Ubuntu Linux 18.04 LTS system for almost 2.5 years. Then heard about 20.04 LTS - seems to be smooth installed-i wanted to try it. I followed this link: How to Upgrade Ubuntu 18.04 LTS to Ubuntu 20.04 LTS. Did everything from command line. Everything went fine. I have Linux installed on PCI NVME SSD and Windows 10 on normal SSD. I used Windows boot loader as the default entry and Ubuntu Linux to be selected if i want to go to Linux. As per that link, i installed not using kernels to clean up some space. I was getting purple grub screen.

But after this upgrade - i get this black grub screen. on which Linuxes - there are two entries - i don't know which one is default. But if i try to select either of the linux - it doesn't boot Linux and it's all dark screen.

Though on Grub - i can select the entry for Windows and it boots it without any issues.

What went wrong? How to come back to normal life with this upgraded ubuntu Linux 20.04 LTS? I can select the advanced option and then tried booting 5.4.0-31-generic(kernel which comes with Ubuntu Linux 20.04 LTS) After that it displays: Loading Linux 5.4.0-31-generic ... Loading initial ramdisk... and then stuck/freeze.

What could be the issue? But after selecting Advanced options for Ubuntu when i select Ubuntu with Linux 4.15.0-101-generic it shows me same messages Loading Linux 4.15.0-101-generic… Loading initial ramdisk… but not getting stuck or freeze and finally loads new Ubuntu Linux 20.04 LTS

What's going on here? I checked that 20.04 LTS is installed and working with this choice root@ashu-XPS-8930:/home/ashu# cat /etc/lsb-release

cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04 LTS"

And the version of Linux kernel is only 4.15.0-101-generic as per this

root@ashu-XPS-8930:/home/ashu# uname -r 
4.15.0-101-generic

Seems to be an existing bug at the time of upgrade Or is it the case that last update was not done well

Update I tried installing various other kernels thinking that it might fix this problem but no luck.

My Desktop has got 6GB Nvidia GTX 1060 which has the compatible recommended nvidia driver as nvidia-396. Tried installing it using

sudo apt purge nvidia-390
sudo apt install nvidia-kernel-source-396
sudo apt install nvidia-driver-396

Please refer to this thread for more details. and disabled noveau using this

sudo vi /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
sudo update grub2

But I am having the resolution problems...800X600 resolution...even xrandr says so that it is the maximum possible resolution.

The same is happening to my Dell XPS 9560 laptop which has Nvidia 1050 GPU. I followed the same steps for it. I am having Ubuntu 18.04.

what could be the issue? It seems 18.04 release is yet not that stable for nvidia.

I have a Dell XPS 15-9560 laptop with 15.6" 4K Ultra HD (3840 x 2160) IGZO IPS 350-nits Touch-screen, and NVIDIA GeForce GTX1050 4GB GDDR5. It's having 4K resolution. Right from the grub screen to Ubuntu, it's having very very small fonts. Is there any way i can increase the fonts size?

This is a real nice laptop - real MacBook Pro killer..getting very popular...and i can see a lot of folks will be having the same issue.

Edit 1

I messed up my current installation of ubuntu desktop 18.04 LTS and have to reinstall it all over again. Just tried this one now: Adding nouveau.modeset=0 to the boot parameters was much better workaround for smaller fonts and i am having much better resolution now. It's much better solution than others as of now.

Seems to ubuntu18.04 LTS is not as stable and much more complex issues with Nvidia graphics card than the previous versions.

Trying to install nvidia driver for ubuntu Desktop 18.04 LTS following this link. Followed all the tips from the above link.

But some what confused in terms of: Whether I am using nvidia driver or nouveau? Whether i am using the right version of nvidia or not? I wanted to use the version 390.

I am having Nvidia GTX 1060 and using Ubuntu Linux Desktop 18.04 LTS.

lspci -k | grep -EA2 'VGA|3D'  
01:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] (rev a1)
    Subsystem: Dell GP106 [GeForce GTX 1060 6GB]
    Kernel driver in use: nouveau

The above command shows that i am using nouveau

while the additional driver shows that i am using nvidia driver

Don't know what to trust?

Edit1 Thanks Luis for your answer. Based on your comments when i am trying to install 396 driver...I am getting the following errors:

sudo apt install nvidia-driver-396

and then when

nvidia-settings is already the newest version (396.24-0ubuntu0~gpu18.04.1).

Edit2 Tried this link Even the proprietary driver install from nvidia didn't worked. nouveau is very much stuck and not going out even when it's being listed in the blacklisted and tried to removed it.

Edit 3 Reinstall didn't solved the issue...seems that it's common bug as mentioned here

Edit 4 Tried these

sudo apt purge nvidia-390
sudo apt install nvidia-kernel-source-396
sudo apt install nvidia-driver-396

and then(added the nomodeset entry)

sudo vi /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

After reboot when i issue this command:

lspci -k | grep -EA2 'VGA|3D' 
01:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] (rev a1)
    Subsystem: Dell GP106 [GeForce GTX 1060 6GB]
    Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia

But the issue is now I have much lower resolution - bigger fonts. How to fix that? What does this line means: Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia That it has all the 4 modules in the order it has been displayed? Current resolution is

xdpyinfo | awk '/dimensions/{print $2}'
800x600

With this change, Secondary monitor has stopped working now. xrandr

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 600, current 800 x 600, maximum 800 x 600
default connected primary 800x600+0+0 0mm x 0mm
   800x600       75.00* 

And it seems this is the maximum resolution that i can get based on the above output.

Edit5 Reverted back the grub nomodeset entry to have the normal resolution. After reboot and closely looking at the log files, this is what i have found(just the relevant lines)

Yes, it's fixed but how and when? I have no idea? Thanks everybody for your help and suggestions.

I am trying to install Ubuntu Desktop 18.04 LTS along side Windows 10, but it's not detecting my Samsung EVO 960 PCIe NVME SSD(500 GB). The same is visible and useable from Windows 10 Professional. What could be the issue?

Rather than directly installing. first i went into the "try without install mode" and opened gparted...gparted showed SATA SSD, other hard drives, USB drive but not the Samsung PCIe NVME SSD.

Anything else i need to have in my bootable ISO image to detect the PCIe NVME SSD? My BIOS mode is UEFI(that's the one via which Windows has been installed), is that the issue as mentioned here? Mine is Dell XPS 8930 Desktop - Intel Core i7-8700(6 Cores Processor with 64 GB RAM, Windows is installed on SATA SSD and I am trying to install ubuntu Linux 18.04 LTS on PCIe NVME SSD).

Edit 1 Rather than trying Ubuntu, I went ahead with the install but end up with some bugs...Ubuntu was not able to detect Windows 10 installation on my computer......Seems that 18.04 LTS is somewhat too early to try it out.

Edit 2 Googled on Internet for Dell XPS desktop/laptop specific issues and found these links: link1 link2 link3

Went into BIOS(F2) and changed the SATA setting to from RAID On to AHCI BIOS warned at the time of saving this setting that either I may not be able to boot my Operating System(Windows 10) or I need to re-install it. I went ahead...couple of times...restart at the BIOS level...Operating system never came up...finally BIOS went into the health check and recovery mode...i reverted back the setting to RAID On and at least Windows 10 is able to boot.

Dell's BIOS doesn't seems to be that easy to work with for dual boot Linux or PCIe NVME drive it seems...will try it later during the weekend.

Edit3 Somehow Ubuntu installer was not able to detect Windows 10. Googled it further and then changed the BIOS back to secure boot enabled and UEFI enabled. Now Ubuntu installer was able to detect Windows 10. Installation happened successfully on my shinning Samsung PCIe NVME SSD without any issues.

I have new Dell XPS 8930 Desktop with the following configuration: Intel i7 8700 Processor(6 Cores) 64 GB DDR4 RAM Intel Optane memory 16GB 2 X 1 TB hard drives. 1060 6 GB NVidia Graphics Came with Windows 10 Professional.

Want to install Ubuntu Linux 16.04 LTS along side Windows 10.

I extended it with another PCIe NVME Samsung EVO 950 - 500 GB SSD. It's being recognized(attached on the mother board via adapter) so there is no h/w issue.

Tried installing Ubuntu Linux 16.04 LTS Desktop(disabled secure boot from the BIOS) - everything went fine. After the install - grub appears and the system directly went into Linux only.

tried boot-repair. Got this recommendation:

The current session is in Legacy mode. Please reboot the computer, and use this software in an EFI session. This will enable this feature. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode.

Went back to BIOS - switch back the secure boot. But now the system going directly to Windows only(no grub)...to fix this tried this in Windows 10:

To solve this, simply go to Windows and open a terminal, then type the following (Need Administrative Privileges):

bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

but now all sort of issues are going on...i cannot even boot via the live CD...Windows Boot manager has been corrupted it seems(fortunately i have the recovery media just created before this).

What could be the problem...when i went into the Windows after the linux being installed and saw from the diskpartmgmt utility of windows...my NVME has become disc 0 and Windows data drive is disc 1 and Windows C drive is disc 2

What could be the issue?

Update 1 Having two M2 devices could be an issue. Intel Optane caches the Windows 10 Pro O/S - analogous to Fast boot. One should disable fast boot to install Ubuntu. In my case searching various forums - I got some hints that i should not use both - Intel Optane as well as Samsung PCIe NVME SSD(not very sure - why) for dual boot purpose. One thing is for sure that Windows disk mgmt software changed the order - it moved the PCIe NVME ahead of others once the grub and Linux was installed into it. My Windows got really badly corrupted(Windows Boot manager got corrupted) - Windows recovery drive couldn't bring it back so I need to install it from the installation media. Luckily it's a new system...so nothing to loose much... But doesn't seem to be an easy fix. My Samsung PCIe NVME stil has the Ubuntu 16.04 LTS and the grub...how to make the dual boot work properly in this particular configuration...I don't want to eliminate the Intel Optane(as it's useful for Windows...makes Windows somewhat faster)...any idea/clues what's going on here?

I am seeing some of the threads like this which are not fully resolved/closed. I am getting this computer.

and want to install Ubuntu on this PCIe NVME SSD like this.

I am okay for a slow boot of bootloader but once I am linux...it's all faster PCIe NVME SSD.

Any suggestions/pointers?

Upgraded from 14.04 LTS to 16.04 LTS but my Eclipse is not getting launched from the launcher on the side vertical bar. Giving me this error: The Eclipse executable launcher was unable to locate its companion shared library.

Reinstalling is not fixing the issue.

Was referring to this thread but it seems there is not some easy way to get the launcher(the correct version of launcher) to get this issue fixed.

Moreover if i follow this link also why the same launcher is able to invoke eclipse when we do this from command line Vs ICON?

I am having Oracle JDK8 and using the installer to install Eclipse for Java EE Developers.

I did a fresh install of Ubuntu Desktop 16.04 LTS - 64 bit along side Windows 10. When the default nouveau driver was used for my graphics card..the color was purple - default color of Ubuntu Linux. When i went to additional drivers and installed the propitiatory but tested driver for my graphics card(Nvidia GEForce GT 610) - during install, apply and after restart the color has been changed to cobalt blue NOT purple.

If i use the last driver Nouveau - it turns back to default purple color.

This is how the desktop looks like - cobalt blue.

Any idea - how to fix this? Thanks for advance.

As per the nvidia website -361 is the latest driver for this graphics card

Update

After 2-3 times restart this issue got resolved on it's own. I am getting the default purple kind of wallpaper with no cobalt blue kind of colors/shades. No change required on the nvidia-361 driver.

I already have Windows 10 and Ubuntu Linux Desktop 14.04 LTS working fine. Later I added another driver and was not able to use the LVM to use the reminder of the second drive for Ubuntu. That's why i thought it's better to install Ubuntu 16.04 over 14.04 After getting the right .iso file and using it...i tried doing that and selected something else...was not able to figure out how to use the LVM at the install time...i tried to quit the install....fortunately i have the rescue disks for Windows and made the backup also....but after quitting the linux installation in between....i am stuck with the grub rescue screen.

Minimal BASH like line editing is supported. for the first word, TAB lists possible        command completions. anywhere else TAB lists possible device or file completions.

And I click Tab and show this:

Possible commads are: [authenticate badram boot break clear configfile continue cutmem echo export extract_entries_configfile extract_entries source gettext initrd insmod linux loopback is menuentry normal normal_exit probe return search search.File search.fs_label search.fs_uuid set setparams shift source submenu terminal_input terminal_output test unset.

Somewhat like that... this link and this one are not working for me....

I had /dev/sda7 as my '/' and /dec/sda6 as swap while /dev/sda2 was /boot/efi and /dev/sdb3 as LVM2 PV...

At the grub rescue i can figure out where my '/' is

ls (hd0,gpt7)/

shows

boot/
etc/
opt/
mnt/
root/
usr/
var/

etc...

What to do? Please help.

Tried these solutions #1 #2

but no success...i am getting the desired results(as per those blogs)but still i am getting to the grub rescue mode only...there is no way

Even after trying these commands from Windows command prompt(after using recovery media and troubleshooting)

BOOTREC /SCANOS
BOOTREC /FIXMBR
BOOTREC /FIXBOOT
BOOTREC /REBUILDBCD
bootsect /nt60 SYS or bootsect /nt60 ALL

No impact...i am just stuck with the grub rescue mode. Can't find any .iso in the USB media to follow the other link.

Update

Tried using Windows 10 recovery media(USB) and reset the computer to it's factory mode also...set secureBoot to disabled, legacy boot support to enabled and fast boot disabled...stuck with the grub command line menu only... (hd0,gpt7) contains my root(/) and other partitions for ubuntu Linux...but sudo mount etc...doesn't work...can't even wipe Ubuntu and get it to Windows 10(was planning to install Ubuntu Linux desktop 16.04)

Posted the issue to microsoft community also.

Want to completely remove Ubuntu 14.04 and re-install(recover) Windows 10 using the recovery media. Once Windows 10 is installed then i would like to install Ubuntu 16.04 LTS.

Update Right now getting this error...i am using the recovery USB driver from Windows 10 only...it should work...but not working...how i can completely wipe out my entire hard driver contents and make sure that Windows recovery drive is recovering my PC...i am ready to loose data if need to be.

Now Windows 10 recovery is also not happening. I am stuck at this screen for ever.

Somehow used the Ubuntu Live USB(16.06 LTS)...try ubuntu and this is how it looks like in gparted.

and this is the pastebin contents

Update(5/5/2016)

Even os-uninstaller is of no help in my case.

I know this question has been discussed in this forum but there is no concrete answer it seems. I have BCM43142 wireless card in my HP desktop(Ubuntu Desktop 14.04 LTS). Wifi works fine but after some time(after 6+ hours) - connection gets very slow and finally doesn't work.

Also gone thru these threads: T1 T2 T3

But doesn't seem to work in my case. I need to reboot the system after every 6-8 hours.

And here is my settings-->Additional Driver As per that i am using the right driver but why it disconnects after 6-8 hours?

Due to my wifi issue as mentioned here I have to upgrade my kernel to 4.2.x following these commands:

$ cd /tmp  
$ wget \  kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.5-wily/linux-headers-4.2.5-040205_4.2.5-040205.201510270124_all.deb \  kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.5-wily/linux-headers-4.2.5-040205-generic_4.2.5-040205.201510270124_amd64.deb \  kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.5-wily/linux-image-4.2.5-040205-generic_4.2.5-040205.201510270124_amd64.deb  
$ sudo dpkg -i linux-headers-4.2*.deb linux-image-4.2*.deb

And i know i can remove that using:

sudo apt-get remove linux-headers-4.2* linux-image-4.2*

This has fixed my wifi driver(Intel wifi 3165) issue. But I learnt that i got the kernel from mainline and it's not a very good idea as I won't be getting any more updates etc... So what's the right way of upgrading the kernel? I heard that i should be using:

sudo apt-get install linux-generic-lts-wily

Want to know what exactly i need to do to upgrade kernel properly? For me it's very important as if i don't have this kernel version my wifi doesn't work. Moreover want to know what will happen to my Ubuntu Desktop 14.04.3 LTS with this upgraded kernel when the new LTS version(16.04 LTS) comes in during April, 2016?

I have another constraint: I need to be on LTS release as some of the software tools/products(DSE and RLEC) that i use - requires 14.04.3 LTS release only. That's why cannot go to 15.10

I am using Ubuntu 14.04 dual booting Windows 10. I had one hard drive and now I've added another. I've allocated around 840GB for Ubuntu. In the past I've been able to mount this drive to

/media/mynewdrive 

But now my needs are changing. I will be needing more space in the first drive (sda) and want to create separate partitions for /usr, /var, /opt and /tmp. I have a few questions:

• I want to create physical volumes and volume groups in /dev/sdb3. Before that I'll need to mount it, but I get the error message that /dev/sdb3 can't be mounted as it's busy. I find the processes that are running and then kill them. One volume group is good enough for me and then within that logical volume I want to put - /usr, /opt, /var and /tmp
• When I am creating them, as /usr is already existing within /, what will happen? I think I need to move all the /usr contents into a new one(/usr of the logical volume), right?

Here is some additional information. This is the /dev/sdb drive, and this is the /dev/sda drive.

My LVM User Interface isn't of much use, but here it is anyways. Most of the posts I see are about when folks used LVM at the time of the install rather than post-install, which is not helping me. Found some good resources on this website. I got some success in this but not 100% success that I was looking for. I wanted to move out:

/home 11G
/opt 9G
/usr 7G
/var 3G
/tmp 1.1G

To my second hard drive so that my Ubuntu can grow in future without any issues. I never used LVM in the past so I learnt from these sources:

• Source #1
• Source #2
• Source #3

The issue that I was facing is that a good number of folks made use of LVM at the time of install, but not later, which is my case. I did the steps in the following order:

1st- Create physical volume on /dev/sdb3
2nd- Volume group 3rd- Logical volumes (home, var, opt, usr and tmp)

I then executed:

mkfs -t ext4 /dev/vgall/opt
cp -r -R /opt/* /temp-opt
mount -t ext4 /dev/vgall/opt /temp-opt

I then made this entry into the /etc/fstab:

#this is volume-opt
UUID=b3d302be-68f6-4804-abb1-ab806326b5a4   /opt    ext4    defaults    0   2

After that I restarted. My /etc/fstab was like this: (before LVM changes)

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda7 during installation
UUID=54458154-6f44-44c9-be44-f91d093d63e6 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sda2 during installation
UUID=E467-1A3B  /boot/efi       vfat    defaults        0       1
# swap was on /dev/sda6 during installation
UUID=74a0518b-2eed-404a-aaa1-a302dbf9f18c none            swap    sw              0       0
/dev/sdb3    /media/mynewdrive   ext4    defaults     0        2
(rw,nosuid,nodev,uhelper=hal,shortname=mixed,uid=1000,utf8,umask=077,flush)

Afterwards, it became like this:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

#UUID=5d610ba0-5ed4-4d08-99dd-946fed50ddd0  /home   ext4    defaults    0   2   

I tried one LV (/opt) at a time, but for me only I can use the /opt to be in LVM. Others failed (home, tmp, usr and var) to work for me, and I don't know why. For others (home, tmp, usr and var) either I cannot login(login loop), or my sidebar disappeared and Ubuntu crashed. What could be the reason for others not to work? I also followed these links:

• Link #1
• Link #2
• Link #3

I finally tried this combination also in /etc/fstab:

/dev/mapper/vgall-home /home   ext4    defaults        0       2

After that I ran

sudo update-initramfs -u 

In order to make the device mappings available during boot, but no fix...only /opt is working fine, but others are not. How should I proceed in resolving this issue.

I m using Ubuntu Desktop 14.0.4. Due to some reasons I need to upgrade to kernel 4.2.5. But after that VMWare Player(i believe version 12.x 64 bit linux) is not working. At the time of start up it is trying to compile the modules for the the new kernel. I uninstalled it and did a fresh install of VMWare Player but the same issue. It is looking for particular version of gcc which is not available.

Looked into this thread also another thread but not able to located gcc-5.2.1 version. Also not able to uninstall the previous version of gcc

This is my current version of gcc

I am using Ubuntu 15.10 Desktop - 64 bit version on intel Core I7 - quad core laptop with 16 GB RAM, 4 GB Graphics card(Nvidia GTX 950M). After successful install - Ubuntu was freezing due to inbuilt and default graphics driver from Ubuntu is not good enough. I went ahead and installed "Nividia GTX 950 M driver" from http://www.nvidia.com/Download/driverResults.aspx/84043/en-us

and followed this link How do I install the Nvidia driver for a GeForce GT 630

Successful install of Nvidia graphics card but I end up with login loop at the time of login(unity and lightdm).

Here are some of my files from /var/log/ syslog

Nvidia installer logs seems to be okay too. What could be the problem? The password is working fine when i use Ctrl+Alt+F1 and then login to the terminal.

Here is the last few lines of nvidia installer logs

I have checked that it's nvidia driver only which is loaded and nouveau is disabled(or not loaded). The nvidia driver i got it from nvidia website only.

How I can get rid of these unwanted GRUB menu entries. My Ubuntu and Windows is getting loaded properly but these unnecessary entries I don't need it. Thanks in advance. This is how the grub.cfg(/boot/grub/grub.cfg) looks like in my case:
