SubinR's questions

Thanks for checking this post/question. Mine is a Dell G5 laptop having a 256GB HDD with Intel RAid ON and Installed ubuntu in the additional 1 TB HDD as Ubuntu doesn't allow to install on Intel Raid RST Hard drive. The grub didn't work because of that. So each time I had to go to BIOS boot menu to choose Ubuntu. I lived with it for almost 10 months without any issues. But last week I got a windows update which crashed it. Even Dell tech support couldn't reinstall windows. Thankfully since Ubuntu was still working, I could backup my data and ship it to them to fix it. Now I got my laptop with fresh installation of Windows.

This time I have decided to change the RAID to AHCI before installing Ubuntu and I did it with the help of this Video: https://www.youtube.com/watch?v=AIhWnmLx51A.

Now, I'm planning to do the installation as Dual boot alongside the Windows 10 once again. For that, please help me with the below questions:

1. Should I shrink the volume in the 256 GB HDD which has the Windows 10 and Install in the unallocated space in that drive or should I install in the 1 TB additional HDD I have along with it? which will be more stable and safer?

2. When I started the installation process without creating any unallocated space / partition from windows in the 1 TB HDD, Ubuntu installer automatically provided the screen to choose the space from the 1 TB HDD. Is that a good option to try it out? Or should I follow the conventional process I've been following all these years (shrink /delete a partition in Windows to create an unallocated space and then create partitions manually with swap space, etc). Which is better?

Please suggest. Thanks in advance!

Getting [FAILED] - Failed to start NVidia Persistence Daemon. And the screen went black with the cursor blinking in 20.04.

My videos were getting stuck and not playing properly in the VLC. So, I tried to update the Nvidia driver. I went to the Additional Drivers tab, it had "using (proprietory, tested) selected by default, but I selected the second option which was having just (proprietory) and clicked apply changes. I got the dialog box to give a secure boot password and I gave it. Upon restart, I got a small blue box with options "Continue to boot", Open MDK, and one more option. I chose "Continue to boot". And the system started to boot but got stuck with a cursor blinking in black screen. It's not successfully booting. I searched this forum and as suggested in other posts, tried to disable the Secure boot option and restarted again. This time, I pressed Ctl + Alt + F1 and I could see the statuses. In that I saw the message [FAILED] - Failed to start NVidia Persistence Daemon. And the screen went black with the cursor blinking.

I don't get the GRUB screen to go to the terminal mode to uninstall or update the driver. How can I fix it? Please suggest.

I have only one root user account. In Ubuntu 20.04, I clicked the "Lock Screen" option from the top right corner.

Once we get the unlock login screen, there is a user icon in the bottom right corner.

Upon clicking it, it takes you to the main login screen. There if you log in the same user it takes you back to the unlock screen login. If you try to unlock by entering the correct password it's not getting unlocked.

So, it only allows you to go back and forth between the lock screen and main login screen.

In the main login screen, the power off option worked and the system had to be shut down. Is it a bug? Can this be fixed? Please suggest.

I tried to install Ubuntu 20.04 in my Dell G5 which has 2 drives. One with Windows 10 on it (256 GB) and another one with 1 TB capacity.

I shrunk the volume of 1 TB by 150 GB and tried to install there.

But Ubuntu installer didn't allow me as I got a dialog after the Keyboard setting said "Turn Off RST" with the message

This computer uses Intel RST (Rapid Storage Technology). You need to turn off RST before installing Ubuntu. For instructions, open this page: help.ubuntu.com/rst

If I make any changes in the BIOS setting, like changing the Intel controller from RAID to AHCI, Windows won't boot and goes into System Recovery.

I didn't have this issue when installing 18.04. While creating the partitions, you need to create a EFI partition with 200 - 500 MB with the usual steps and the installation will be completed succesfully.

On restarting, you will not be getting the GRUB but instead Ubuntu will boot by default. If you need to boot Windows, you will have to go to the BIOS and choose from the UEFI boot option each time.

Once 18.04 installation is complete, you can upgrade it to 20.04.

After upgrading I installed the KDE desktop and at the login screen I chose the "Ubuntu on Wayland" option.

After doing these 2 things, I lost the new features of 20.04 like the Ubuntu boot screen with Dell logo and the power off/log out blur effect screen. Not sure how to get that back.

I chose the 'Ubuntu on Wayland' session from the settings like icon from the right corner of the login screen and logged in.

Once I logged out and logged back in the Ubuntu default session, the theme and icon appearance got set from the Wayland session.

How can I restore the default theme and appearance of the Ubuntu 20.04 back ?

I lost the new features of 20.04 like the Ubuntu boot screen with Dell logo. And the power off/log out blur effect screen instead getting Wayland's dialog box. Not sure how to get that back. Any suggestions would be great. Thanks!

I installed the KDE desktop over the default Ubuntu 20.04. After that I'm not seeing the default Ubuntu logo with Dell logo which is the new 20.04 feature. Instead seeing the Kubuntu logo.

How can I restore it back to the default Ubuntu Boot screen?

I tried

sudo update-alternatives --config default.plymouth 

I was able to choose the ubuntu in manual mode:

There are 6 choices for the alternative default.plymouth (providing /usr/share/plymouth/themes/default.plymouth).

Could someone help please? Thanks in advance!

I bought a new Lenovo B50-80 laptop with 4GB RAM, 500 GB HDD preinstalled with Windows 7 Professional. I would like to install Ubuntu alongside the existing Windows 7. For that when I tried to create a new partition using the Disk Management, it is not allowing me to do it. I'm getting an error message that I cannot create more than 4 partitions. I was able to shrink the C: volume and create unallocated space. But the unallocated space is showing as unusable in Ubuntu installation.

I tried to do the following:

1. Copy / take back up of the Lenovo D: which has the Lenovo applications and Drivers. And delete the D:

2. Now, we have a new One unused partition of 25 gb unallocated space for installing the Ubuntu.

I tried to install Ubuntu in the unallocated space of 25gb. Since it is a single partition, Ubuntu is asking me to create another partition allocating 4gb for the swap area. When I try to do that, the remaining 21gb space is becoming unusable (Since, the Windows partition does not allow more than 4 partitions).

My question is can we install Ubuntu in the unallocated space of 25gb in a single partition? Is Swap area partition necessary? Can we install Ubuntu without a Swap area? Can Swap area be allocated as file space instead of a separate partition? What will happen if I install without a swap area?

I had installed Ubuntu 14.04 2 weeks back on my new laptop along side Windows 8. 1. And it was working fine. But yesterday after I connected Ubuntu with my TV using the HDMI cable, the cursor/ pointer stopped working. The pointer is not visible and my touchpad is not working.

I connected the hdmi cable with youtube in Firefox. But only the wallpaper was visible on the TV. Also the right click menu, alt tab window, etc was also visible. But the side menu and the Firefox window was not visible. The pointer was visible on the tv and the touchpad was working, I was able to move the pointer.

After I removed the HDMI cable, my cursor/pointer disappeared and my touchpad is not responding! ! I tried to restart many times, but still no luck. Its still not visible in the desktop. The pointer is visible in the login screen, but is not responding to the touchpad.

I tried to login to my KDE session, there too the pointer is visible but is not responding to the touchpad. It is not moving.
