What are the usual problems or issues that cause Wi-Fi to stop working on an Ubuntu system?
As the link https://packages.ubuntu.com/search?keywords=boomaga&searchon=names&suite=all§ion=all suggests, the Boomaga software is no longer available in Ubuntu 26.04.
I know that I can add the appropriate PPA and still use the old version (taking any risks).
However, my question is this:
What is the best way to easily preview printouts, rearrange pages, combine print outs, make booklets, or print multiple pages on a single sheet (all in one software) in Ubuntu 26.04?
Would you have some advice on a straightforward way to type in an inverted question mark using English (Us, alt. intl.) keyboard in Ubuntu 22.04?
I have tried many of the options as available from the community but none seems to work (at least for my simple installation of Ubuntu 22.04).
Many thanks.
My Laptop is in a secure room and does not travel.
No security issues.
Ubuntu used to have this feature, Has it gone now?
I own a Digidesign Mbox 2 sound card, and have been using it with Ubuntu with no problems. Since I upgraded to 26.04, the sound card disappears randomly with the audio output cutting out and the device disappearing from the output menu.
If I enter alsa force-reload into the terminal, the sound card will come back and continue to work. Is there anything I can do to prevent the sound card from disconnecting randomly?
I have used ansible to install firefox with the following block:
- name: Add Firefox repository
apt_repository:
repo: 'ppa:mozillateam/ppa'
state: present
update_cache: no
become: yes
This has always worked but stopped working after switching to Ubuntu 26.04, giving the following error:
TASK [Add Firefox repository] **************************************************
[ERROR]: Task failed: Module failed: Unable to get required signing key

I read that apt_repository is being deprecated in Ubuntu 26.04. But I am not sure whether it is the cause here.
Can someone help explain how I can fix the ansible block to install from the PPA?

What can i do to get this fixed?
I have a 2014 MacBook Air 6,2. My wifi and camera don't work and will have to be worked out. These items should just work out of the box with no messing about! I'm sure I am not the first nor the last to have these issues. I should think that these sort of issues could be worked out during installation. Why not?
I have this keyboard layout on a HP laptop. As you can see, I have the keys [ and ] around the space bar, & to the right of the space bar, _ near backspace, - near the right shift key.
Sadly all these extra keys, including the backspace key, do not work. Anyone with a solution?
Update 1:
I am using Ubuntu 24.04 on a HP EliteBook 830 G6, i5, 8GB RAM. For the layouts, I have tried all under the screenshot below.
Chrome web browser is taking a lot of memory with one tab.
For context I have 1 tab open, but Chrome is taking more than 5GB of RAM. I am using Mission Control as a task manager. I am on Ubuntu 24.04.
My computer is:
Host: Blade 14 - RZ09-053
OS: Ubuntu 24.04.4 LTS x86_64
CPU: AMD Ryzen AI 9 365 w/ Radeon 88
GPU: NVIDIA c4:00.0 NVIDIA Corporation
When I try to boot into it from power off, I unlock the disk with the disk password, the Ubuntu logo shows for a bit, flickers off, on, and then off... and then the screen goes and stays black.
I am able to boot into recovery mode from Grub, and then I can log into my user and use the OS normally.
The NVIDIA driver I use, found in Software & Updates, is nvidia-driver-595-open.
I also often get an error after booting into the OS and using it for a few minutes with the Title:
Xorg assert failure: Xorg: ../../../../dix/privates.c:382:dixRegisterPrivateKey:Assertion '!global_kays[type].created' failed
I believe they may be connected because I assume the screen going black is a driver issue, but I don't know.
Another thing to note is that sometimes my computer just randomly freezes, with no input available, and I have to power it off, which also sucks and might be related.
I have already done sudo apt update and sudo apt upgrade, I've done a lot of searching.
Thank you!
I have a computer hooked into my TV and surround sound, every time I turn either one off then on again it negotiates 4k instead of the 1080 I require. How do I lock in screen resolution regardless of whats going on? Surviving reboots and and powering any of the attached devices and maintain the 1080 resolution?
I am using a Lenovo Legion R9000P ADR10 laptop. The internal speakers produce a very flat, quiet, and tinny sound with absolutely no bass. It feels like the subwoofers/woofers are completely disabled, and only the tweeters are functioning. Audio works perfectly fine under Windows, confirming it is a Linux driver/kernel configuration issue (missing pin quirk for this specific model).

I have been trying to find a PDF viewer on Linux where I can remove blue tones. I am a beginner with this operating system and I still do not know it very well. I have gone into system settings and I have seen that it is possible to remove blues there, but it only affects the desktop; when I open the PDF viewer, the blues are not removed (nor in the browser). I would like to know if there is any program that can do this or if it is possible in some way to have a PDF viewer where blue filtering can be applied.
I recently started testing gaming and emulation performance on Ubuntu and I noticed that some games run smoothly while others have random stuttering or FPS drops even though system usage looks normal. I’ve already tried updating GPU drivers and switching between Vulkan and OpenGL renderers, but performance still seems inconsistent depending on the game and desktop environment.
System details:
I wanted to ask if this is something commonly related to shader compilation, compositor behavior, power management, or background services on Linux. Are there any recommended optimizations or settings that experienced Ubuntu gamers usually apply for smoother gameplay and better frame pacing?
My personal guess is this is due to sssd

I'm giving Ubuntu a comeback, but something really annoying for someone migrating from Win11 are those apps whose windows are frameless (i.e. no contour) and/or shadeless, giving no visual clue where the window begins/ends when its superposed onto a similar background. Is there a way to force an app to show its window frame contour or to at least give it a shade to differentiate its limits from the background? Thanks, Grohlfer
I was cleaning up old apps and programs when I deleted a file I thought I didn't need called colord (I think) which had something to do with colour management. I was looking at flatpaks using "software" or was it a flatpak manager. I don't think it was snap, but could have been. As it uninstalled, my laptop stopped.
I can login to the command line.
I cannot seem to reinstall colord from flatpak and nothing else I've tried restarts gnome. I think most things I've tried refer to x.
How can I restart the desktop?
I have a Galaxy Book 2 Pro 5G. I mentioned the issue with the speakers not producing sound last time, but it was only partially resolved—the sound disappears again after restarting the computer. After seeing this post, I feel there might be some hope, but my technical knowledge is limited, and I don’t understand where to go or what to do. Could someone please be so kind as to provide detailed instructions?

I frequently run backportpackage to upload .deb source packages to a PPA to have them build on Launchpad and get published there. In recent days this has been (permanently?) failing:
$ backportpackage ...
...
Uploading to ppa (via ftp to ppa.launchpad.net):

Any suggestions what might be going on? Is this related the recent issues that has taked down all of Launchpad recently in April/May 2026?
I know the title is quite generic, but I have more than one problem with external monitors attached to the docking station.
I am using Ubuntu 24.04.4 on a Lenovo Legion Pro 5 with Nvidia Geforce RTX. I have a HP USB-C Dock G5 attached to the C-port and two monitors connected to it with DisplayPort.
The computer has some problems identifying the monitors: Every time I turn it off and on again, it forgets the configuration I set the last time, even if it is correctly stored in .config/monitors.xml:

I noticed sometimes it used to add a second configuration by himself, so I set the file to read-only but this did not solve the problem. I also tried to copy it into /var/lib/gdm3/.config/ .
Also, sometimes one of the monitors turns off and on again while I am working (it takes about 2-3 seconds); every time I lock the screen, it stays black and does note receive signal until I manually turn it off, lock again the screen, turn it on and unlock computer.
Is there a way to fix all these problems? Don't hesitate to ask for further details.
I noticed that the configuration problems happens only at startup, but if I restart it the monitors are placed correctly. Anyway I would like to avoid having to start and restart the computer every time I need to use it.
My Galaxy Book2 Pro 5G's speakers were working, but after restarting the computer, the sound disappeared again. So I tried running some code, and the sound came back.
I executed the following commands:
sudo apt install -y alsa-tools
wget https://github.com/joshuagrisham/galaxy-book2-pro-linux/raw/main/sound/necessary-verbs.sh
chmod +x necessary-verbs.sh
sudo ./necessary-verbs.sh
Is there a way to automatically execute some code with this effect at boot?
I'm using Ubuntu 22.04 LTS, and I'm having trouble refreshing the snap gnome-42-2204.
When I run the command:
sudo snap refresh
I get the following error:
error: cannot perform the following tasks:
What I have tried so far:
sudo snap install core
sudo snap refresh core
sudo systemctl restart snapd
sudo rm -rf /var/lib/snapd/cache/*
Despite trying all the above, the problem still persists.

Question:
Is this a problem with the Snap Store or with the snap package gnome-42-2204 itself? Is there any way to force verification, downgrade, or remove the affected revision?
Any help or workaround would be greatly appreciated.

I am trying to run sigrok with real HW. However, running pulseview, there is no real HW possible. I suspected that this was due to sigrok not having the privilege to access the HW, and so I ran it as root, and I was able to access the HW.
My question is:
How do I run this without root? I assume I need to change the gid or uid of the device file to be able to access it. If so:

Perusing thousands of photos from my smartphone transferred to my computer is a bit of a challenge. Separating the wheat from the chaff is a time consuming late-night endeavor. What makes this particularly challenging is WhatsApp, as it is configured on my phone (by default) sends/receives compressed, lower-res images, rather than full-res. Sharing a photo taken by one's own smartphone would, to my understanding, leave the full-res photo on the phone and additionally create and save a compressed, lower-res and renamed copy of the sent photo in a WhatsApp directory, effectively creating a lower-res duplicate.
As the first iteration of my envisaged workflow I'd like to select unique photos only (over a range of folders and sub-folders). If a given photo exists more than once (either at the same size (same resolution) or at different sizes (different resolutions), I'd like to select only one copy and explicitly only a copy of the highest available resolution (ignoring all lower-res copies).
Building on these two related questions
How could I accomplish this in a jiffy?
The upshot / meaning of this exercise would be to include in the initial photo selection also photos received in WhatsApp - as long as these are unique and no higher-res copy exists elsewhere (on my phone / computer).

I have installed Ubuntu 18.04 LTS. Then installed Brave web browser and made it default. Now when I click on any link in any application whatsoever its either a) does not do a thing (like if I click in Discord for instance) or b) CLOSE the Brave browser instead (from Telegram for instance)...
What am I doing wrong here? Thanks!

I have been using the GUI (right-click => Compress) to try and compress a .tar containing 3 videos totaling 1.7gb (.H264 MP4s). gzip, lrzip, 7z etc. All do nothing to the file size and the compressed folder is also 1.7 gb.
I then tried running lrzip from the command line (in case it was a GUI problem), and used the -z flag (extreme compression), and this was my output.

As the compression ratio shows, the actual size of the compressed folder is bigger than the original! I don't know why I am having no luck, lrzip in particular should be effective according to random reviews I have read and the official docs (files larger than 100Mb, the larger the better) - see https://wiki.archlinux.org/index.php/Lrzip
Why can't I compress my files?
