It's so weird that I have to shutdown Windows 11 to be able to use the internal laptop mic on Kubuntu. Restarting and then booting into Kubuntu completely disables the internal mic. Any explanations?
As mentioned here, "you must create the mount point before you mount the partition." But after adding the following lines in fstab and rebooting the system
/dev/sdxy /media/user/hdd_mount_point ext4 defaults 0 0
tmpfs /mnt/tmpfs_mount_point tmpfs rw,nosuid,noatime,nodev,size=4G,mode=1777 0 0
the mount points (target directories) hdd_mount_point and tmpfs_mount_point are automatically created if they do not exist. I know that you can make a mount point if it does not exist by adding the X-mount.mkdir option to mount command as mentioned in its manual page, but I really like to know if this option is implicitly used when mounting file systems via fstab.
And NO, it is not a duplicate of Automatic Adding of Filesystems to /etc/fstab
As the title says telegram system tray icon is hardly visible. All appearance settings are on default.
But when I change Colors from Breeze to Breeze Dark it gets fixed.
The problem is that I like Breeze colors and I do not want to change it. Additionally, I noticed the problem is with /usr/share/color-schemes/Breeze.colors because when I change ForegroundNormal=35,38,39 from [Colors:Window] tag to ForegroundNormal=239,240,241 that is the value used in BreezeDark.colors the icon is changed to white but I get other color problems. Now looking for a solution.
Also I tried replacing all Telegram icons in /usr/share/icons/breeze/status/22 and /usr/share/icons/breeze/status/24 by /usr/share/icons/breeze-dark/status/22 and /usr/share/icons/breeze-dark/status/24 and nothing changed.
I installed Ubuntu 18.04 right now and after connecting to the internet instead of a network icon there is a question mark. There is no network issues, but that question mark is annoying.
After the installation of any programs I get the following error
Processing triggers for libc-bin (2.23-0ubuntu7) ...
/sbin/ldconfig.real: /usr/lib/nvidia-375/libEGL.so.1 is not a symbolic link
/sbin/ldconfig.real: /usr/lib32/nvidia-375/libEGL.so.1 is not a symbolic link
What is this error and how can I solve it?
Is there any difference between cp -r /source /destination and cp -a /source /destination when I am copying from NTFS to EXT4?
I used tar to archive some important files. After converting all my files to .tar I tested it and there was no problem so I deleted all my files. Next day I tried it again and I got this error:
tar -xvf my_file.tar

*/

My files were stored on an NTFS partition and on an external hard drive. Ubuntu Disks program says SELF-TEST FAILED when I press Start Self-test. What can I do now to recover my files? They are important stuff of my university.
Today I upgraded my system by running sudo apt-get update and sudo apt-get upgrade.
At the end of the installation process I am getting asked : What do you want to do about modified configuration file 20auto-upgrades? I don't know which option to select.
I cannot open djvu files by qpdfview while qpdfview-djvu-plugin is installed. I really like qpdview and don't want to use other applications. Any suggestions?
When I install applications like Android Studio or programs like Oracle JDK in home directory by extracting tar archives, after running the .sh file, they make changes on home directory such as making configuration files and folders. I want to know that can they access other system folders in my root directory and make changes in them?
I want to wipe one of my partitions say sda2 (I don't care about data security in this case). Does
dd if=/dev/zero of=/dev/sda2
damage sda1 and sda3 or even partition table?
I downloaded netbeans-8.1-linux.sh. After installation there are many .exe files in the installation folder such as netbeans.exe, netbeans64.exe, app.exe, app64.exe, nbexec.exe, pre7_app.exe and etc. Why are they there?
EDIT: I installed NetBeans by Ubuntu Software and it hasn't even got JavaFX plug-ins! It also installs openjdk 1.8.0_9 and replace it with already installed oracle jdk1.8.0_92!
I want to install my apps by apt-get install from terminal but there aren't any options to get an app name in Ubuntu Software. What can I do?
I hadn't any problem with 14.04, but 16.04 is so buggy. I can't reboot Ubuntu after installation is completed from live USB/DVD and I must press the power button. Also sudo reboot and sudo poweroff don't work when Ubuntu is booted. I updated Ubuntu but the problem still exists.
I cannot type in Firefox, Terminal or File Manager's search bar when I open them, but I can if I open a new window or multiple windows without closing the first window. What can I do?
Edit 1: The problem still exists after updating Ubuntu by apt-get upgrade and apt-get dist-upgrade.
Edit 2: The problem only occurs when Ubuntu is installed by acpi=off.
When I was making a bootable usb drive by Startup Disk Creator utility, it said that the OS version of ubuntu-14.04.3-desktop-amd64.iso is Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805). Why does it say such thing? By the way I am running Startup Disk Creator on 14.04.3 LTS.
I ran the following code in R according to this page

- Are all Ubuntu download servers an exact copy of the main server?
- Can a software be on a server but not be on another server?
- Can the version of a software be different on different servers?
- Where is the main server?
I have three primary partitions. One ext4 format for Ubuntu, one ntfs format for Windows (C:) and one ntfs format for sharing files between Ubuntu and Windows (F:). I installed VirtualBox on both Ubuntu and Windows. I went to VirtualBox Settings and set the Default Machine Folder to F:\VirtualBox VMs on both operating systems.
I created a dynamically allocated VDI (VirtualBox Disk Image) in F:\VirtualBox VMs\my_VM_name and put virtual optical disk file into F:\my_os_name.iso and ran it on Virtualbox in Windows. After installation I also installed VirtualBox guest additions.
I went to Ubuntu, mounted the (F:) partition and added my_VM_name.vbox in VirtualBox. But when I ran it, I get the following error:
The virtual machine execution may run into an error condition as described below. We suggest that you take an appropriate action to avert the error.
The image file
'/media/Ubuntu_user_name/A_Hexadecimal_number/VirtualBox VMs/my_VM_name/C:/Program Files (x86)/Oracle/VirtualBox/VBoxGuestAdditions.iso' is inaccessible and is being ignored. Please select a different image file for the virtual DVD drive..
I closed VirtualBox and ran it again. But it introduce a new error
One or more virtual hard disks, CD/DVD or floppy disk image files are not currently accessible. As a result, you will not be able to operate virtual machines that use these files until they become accessible later.
Press Check to open the Virtual Media Manager window and see which files are inaccessible, or press Ignore to ignore this message.
I pressed the Check and the Virtual Media Manager window shows The following error in the Optical disk tab:
my_os_name.iso*
*Location: /media/Ubuntu_user_name/A_Hexadecimal_number/VirtualBox VMs/my_VM_name/F:/my_os_name.iso
How can I config VirtualBox to work without any errors in both Systems?
In Windows I am familiar with .exe and .dll files (two essential files for running or writing a program). But when I want to install manually an application in Ubuntu, most of the time I will need extra packages. What are these packages? Are they like dll files in Windows? Where are they save in Ubuntu? What types of packages are there? How can I find what packages are needed to install an application and where can I find them?
