When I adjust the keyboard backlight using the quick settings in the top‑right corner, the keyboard light does not turn on no matter how I move the slider.This issue does not occur on Fedora or Arch Linux.
I have finally managed to get the internal camera on a Macbook Air 2017 to work thanks to this post: https://www.reddit.com/r/Ubuntu/comments/1kdpjqw/how_to_make_macbook_air_webcam_work_on_ubuntu_2204/
When I try the camera with cheese I get the following message: "Cheese is nor responding", "Force quit" or "Wait".
What should I do to make the video recording work?
So I just installed Ubuntu server on my laptop and after I reboot I can't login I type the right login and password but it still displays login incorrect
When I'm connecting to a Windows-computer from my laptop (using Ubuntu 24.04.4 LTS), the mouse wheel acts a bit weird. It's mostly noticed in games, where the mouse wheel moves several clicks at once (so in stragegy/4X games I only have a couple of zoom levels since it zooms in/out several levels at once, and in first-person games with an inventory or similar it skips every 2-3 items every time I scroll), but I also notice it when using TeamViewer/Rustdesk, where it moves web pages many times faster than it would if I were to visit the same web page in Ubuntu.
Is this something known? It seems to happen no matter which mouse I use (I've tried several models of Logitech mice, as well as a couple of other brands), and it happens no matter the remote connection I use (Steam Remote Play, TeamViewer, or RustDesk).
I've tried using imwheel, but it seems to have no effect at all in games, even with extreme settings in either direction.
Just now I encountered a error where Firefox would not download items, hence I found a solution where you need to reinstall it but not using snap. Without further hesitation, I deleted Firefox via the app center. I then reinstalled it using the .deb. As I opened it for the first time, to my shock, I forgot to export my passwords from my old Firefox. I know this question seems stupid, but is there any way to recover them?
I’ve got a ZIP file that I locked a while ago and now I can’t remember the password at all. I’ve tried a few guesses but no luck so far. Are there any simple tools or methods that actually work? Not looking for anything too complicated, just something that can help me get back into my file.
When I type in a sudo command, it asks for the password of the user, I know my password but i simply cannot type anything there where Im prompted to and am locked out from using commands. Does anyone know how i can resolve this?
I'm running Ubuntu,and I'm getting a "bash G++ command not found" error,even though I just installed it with 'sudo apt install buil-essential'. I've tried refreshing the package list, but it's still not working. When I check the version with 'gplusplus --version', I still get command not found'. Any ideas on how to fix this?"
I can not upgrade from Ubuntu 22.04 to Ubuntu 24.04.

I installed Ubuntu 24.04.4 on a iMac 19.1 computer and the audio did not function. Ubuntu 24.04 uses PipeWire and WirePlumber for the audio/video implementation. Pipewire is the core multimedia server and WirePlumber is the session/policy manager that handles how data streams are connected and responds to events like plugging in headphones or when xRDP is used for screen sharing. These were not properly configured form the iMac when Ubuntu was installed. The way to see current sources and sinks for the session is to use the CLI command
wpctl status
Furthermore
Currently my keyboard layout is:
I added:
➜ ~ cat /usr/share/X11/xkb/symbols/cust
partial alphanumeric_keys
xkb_symbols "cust" {
include "us(euro)"
name[Group1]= "English (Cust)";
// AltGr + c → ç
key <AC02> { [ c, C, ccedilla, Ccedilla ] };
// AltGr + s → ş
key <AC03> { [ s, S, scedilla, Scedilla ] };
include "level3(ralt_switch)"
};
and also added the layout block in /usr/share/X11/xkb/rules/evdev.xml
The settings does detect my layout, but as you see in the image it becomes acsfghjkl instead of asdfghjkl and it messes up the layout.
I want to override the s and c key such that alt_gr+c or alt_gr+s adds a cedilla. What am I overlooking.
i try to install Psiphon with wine but it doesn't work
I'm on 24.04.4 LTS, and window animations randomly stopped working, after I unplugged my hdmi cable for 10 hours.
I plugged it back in in the morning and there was no animation at all.
This is all I know.
I have tried rebooting
Here is some more information, I think.
Window animations, as in, geany effects. Closing a window has an animation. Instead of immidiately dissapearing, the window fades. clicking "show apps" has a fancy animation as well. The apps list comes up from the bottom of the screen, instead of just appearing
None of these are working on my pc.
6.17.0-20-generic
I am running my display like this: pc, soundbar, monitor.
Graphics card: gtx 980
I have checked accesibility. reduce animations is off.
I have checked the terminal redout of that same setting.
Something like "window-animations-enabled:" and it was set to true

I`m just trying to install Ubuntu 22.04 in my notebook, but I need to have full disk encryption enabled and I would like to define the size of my swap partition.
When searching for answers I saw multiple mentions that Ubuntu 22 doesn`t need a swap partition, because it would use swapfile. However If I proceed with the default installation (plus enabling FDE) I get a swap partition anyway:
nvme0n1 259:0 0 238.5G 0 disk
├─nvme0n1p1 259:1 0 512M 0 part
├─nvme0n1p2 259:2 0 1.7G 0 part
└─nvme0n1p3 259:3 0 236.3G 0 part
└─crypt 253:0 0 236.3G 0 crypt
├─vgubuntu-root 253:1 0 234.4G 0 lvm
└─vgubuntu-swap_1 253:2 0 1.9G 0 lvm
So I went for a new install following these tutorials: (They are mostly the same)
Note: Its a nvme notebook
Following the tutorial, I ran command for command with no error, but got a warning when partitioning:
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot or after you
run partprobe(8) or kpartx(8)
The sgdisk --print $DEV returns as expected:
Number Start (sector) End (sector) Size Code Name
1 2048 1574911 768.0 MiB 8301 /boot
2 1574912 1579007 2.0 MiB EF02 GRUB
3 1579008 1841151 128.0 MiB EF00 EFI-SP
5 1841152 500118158 237.6 GiB 8301 rootfs
However when I get to the point of using LUKS, the first time it works as expected, but the second command fails: This command works:
cryptsetup luksFormat --type=luks1 ${DEVP}1
And then this command fails:
# cryptsetup luksFormat --type=luks1 ${DEVP}5
Device /dev/nvme0n1p5 does not exist or access denied.
I`ve also tried like this:
# cryptsetup luksFormat ${DEVP}5
Device /dev/nvme0n1p5 does not exist or access denied.
Because that is a difference between both tutorials so far... I`m on a live boot from USB.
How can I encrypt the last partition so I can continue on?
OR how can I achieve the Ubuntu 22 install + LUKS FDE + Custom SWAP?

I tried the amdgpu.dc=0 on normal boot option but the error persisted. Note that the boot is successful on 20.04.3 and 21.04. What needs to be done for successful boot? This problem is not observed with my NVIDIA card.

After installing Ubuntu on my laptop and even changing the hard drive (for another reason) I cannot boot from the Windows installer anymore. It's just showing a box when system turns on which has two menus: Boot Menu: Ubuntu and App Menu: [empty]. And then nothing happens.
I started to upgrade my server from Ubuntu 18.04 to 20.04. After reinstalling xen / qemu in the dom0 XEN cannot start domains after upgrading from 18.04 to 20.04 dom0 and all domU instances worked as expected.
Next I updated a domU from 18.04 to 20.04. The update went well, but the domU crashed on boot.
The configuration of the domU looks like this:

I tried to boot with an Ubuntu daily build in order to have the latest kernel, but I had no luck.
I managed to access my terminal, update-grub didn't help, but when I typed sudo apt update I had E: Error reading the CPU table. /usr/share/dpkg/cputable was missing, I copied a version of the file I found in /snap/core18/941/usr/share/dpkg/cputable and now I have E: Cannot find dpkg tuplet or triplet table.
I deleted my Ubuntu partition, but it still shows up in the boot menu. When I did bcdedit it doesn't show up, just a Windows Boot Manager and Windows Boot Loader as shown below.
Could one of those accidentally somehow be Ubuntu?

I was at a friend's and he said he fixed it by getting that grub gnu pop-up removed when I start my Windows which he did, but when I got home it was still in my boot menu
I have removed Windows partitions in order to completely remove Windows 10 and continue with Ubuntu, however even after updating grub using sudo update-grub it still shows the Windows bootloader. Its output was this:

I also want to remove the grub menu which shows before booting so that it takes less time to boot up. I tried it with Grub Customizer. After booting up it takes even more time. I want to know how can I change the grub settings so that it takes least amount of time to boot?
Some information about my system is:

I have Windows dual booted with Ubuntu. Recently I moved one of my free partition so that it would be near the Ubuntu partition and I could expand the Ubuntu partition, but when I moved the free space partition and rebooted the system, I got stuck at the GRUB terminal instead of the GRUB boot menu.
When I use F12 to get the boot options and choose Ubuntu from there, it redirects me back to GRUB terminal. Windows however boots normally.
Here is the GRUB terminal output that I tried diagnosing.
GNU GRUB version 2.02~beta2-36ubuntu3.14

I listed the drives using the ls command and I think that (hd0,1) is the Linux partition. Can anyone guide me as to what should be my next step?
I'm trying to install Ubuntu from a USB flash drive. The purple screen of Ubuntu doesn't show up, it only says
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
and stops there.
I tried the USB with another computer and it works perfectly. I thought maybe the problem is my computer which is Toshiba Satellite L50 but I couldn't find any helpful comment on the internet.
I tried both FAT32 and NTFS as USB format, but nothing changes.
I also thought maybe the problem is I'm using Windows 10 currently and searched for that. I have disabled "Turn on fast startup", but again nothing changes.

Please notice that it is the first time I'm trying to install/use Ubuntu.
I'm a total newbie on Linux as of two days ago. I'm running Ubuntu 16.04. I just got a new HP Pavilion with Windows 10 64-bit.
I know enough to safely set up a dual boot system without breaking anything, but the GRUB boot menu is a little frustrating with so many options. I really only want the option of booting from either of the OSs installed, but I am met with a list of options.
If all of this is necessary I guess I'll leave it, but I'd really only like to have the two operating systems as boot options. Do I really need this big list of boot options or can it be reduced somehow to only be the two OS options?
Boot menu:
I'm using Xubuntu/Windows 10 dual boot. I installed the NVIDIA CUDA toolkit to use GPU version of TensorFlow. After rebooting it, it got stuck at
/dev/sda6: clean,..... for a very long time and the laptop was out of charge.
After I plugged in and turned it on, it got stuck at a kernel panic screen:

Here is an example above. It also does the same thing on other sites with other video players, but I figure this is one of the more well known ones.
Any help?
I have Ubuntu in dual boot alongside the original Windows 8 install. My grub shows a ton of options. The first one loads Ubuntu alright. In the past I tried loading Windows 8 (which I hardly ever use) and after loading Windows 8 and restating the machine it somehow managed to get grub disabled. Which option loads Windows 8, and is there a way to clean up grub to show only relevant options?
So, I went and did something very stupid. I have ubuntu-toolchain-r repository added to repositories which has up to some time ago provided libgcc1:i386 among other things. For a some time now the i386 packages have been shown as kept back during upgrades. I've ignored those since they are rather vital libraries but today I decided to look into it a bit.
I stumbled upon this "The following packages have been kept back:" Why and how do I solve it? and went to use the aptitude gui approach without realizing that it shall do basically the same thing as apt-get dist upgrade and as the gui hanged for a while, it took in my key presses after a while without me having a chance to do anything before it started to do some horrid package removing to my misfortune. I went and killed the aptitude process but a lot of damage was already done.
So afterwards killing aptitude I carefully went through the list of packages that it had removed and re-installed those. All except the ones that need ia32-libs or libc6:i386, meaning for example my wine and lots of other 32-bit applications and packages that I use because it all comes down to the fact that I can't re-install libgcc1:i386 package since it breaks libgcc1 package and vice versa (same goes for libstdc++6).
ahti@ahti:~$ sudo apt-get install libgcc1:i386

libgcc1 : Breaks: libgcc1:i386 (!= 1:4.9.2-0ubuntu1~12.04) but 1:5-20150401-0ubuntu12~12.04 is to be installed
libgcc1:i386 : Breaks: libgcc1 (!= 1:5-20150401-0ubuntu12~12.04) but 1:4.9.2-0ubuntu1~12.04 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
So previously libgcc1:i386 was kept back in my system not causing any problems. Now that it's not there anymore and can't be re-installed it's bringing me a lot of things I can't re-install or use.
Here are results for apt-cache policy command:

Also I do have foreign-architecture i386 in my /etc/dpkg/dpkg.cfg.d/multiarch and here's a result of aptitude install wine command.
Is there anything I can do? This was a classic case of "if it ain't broken, don't fix it". Please help?
My system is 64-bit Ubuntu 12.04.5 with 3.2.0-80-generic kernel and gnome-session-fallback.
I don't like the themes I have in my system (Xubuntu 11.04) by default.
Is Xfce Look the only place where I can get new themes?
Can I run themes that are made for Gnome, for example?
