In the Gnome shell in Ubuntu 24.04, when I start Firefox and a session with more than one window is automatically restored, each window gets a notification "Firefox is ready". Then, when clicking repeatedly on Firefox in the dock, it will cycle through all the windows until the notifications are dismissed, then cycle through all of them a second time until the "asking for attention" thing has been satisfied. Only then can a click activate the "second click action" (in my case, spreading the Firefox windows on the screen).

With routinely many windows in my Firefox session, this is extremely tedious.

How do I turn this off? Is this a Firefox thing, a Gnome thing, or is it an outright bug?

I'm facing a serious issue with my Ubuntu system and would appreciate any help.

My Ubuntu suddenly became very slow and unresponsive. I restarted the computer, but the same problem happened 2–3 times. After another restart, the system started working normally for a short time.

Then I noticed that my files and folders started disappearing one by one. After most of the data was gone, an Ubuntu upgrade/update popup appeared.

I have very important data on this system, and I'm worried about losing it permanently.

Has anyone experienced this issue before? What could have caused it, and is there any way to recover my data?

System details:

• Ubuntu version: 24

• Storage type: SSD

Any help or suggestions would be greatly appreciated. Thank you.

I am experiencing an issue where my HP Laptop's Media Keys / Action Keys (F1-F12) suddenly stopped working directly. In windows 11 before, it normally clicked or press this button without Fn combination.

F1 : Help
F2 : Decrease Screen Brightness
F3 : Increase Screen Brightness
F4 : Switch Display
F5 : Keyboard Backlight Toggle
F6 : Mute Audio
F7 : Volume Down (-)
F8 : Volume Up (+)
F9 : Previous Track
F10 : Play/Pause
F11 : Next Track
F12 : Airplane Mode

I tried:

1. Checked BIOS settings : changing "Action Keys" (Enabled/Disabled) has no effect.
2. Checked GNOME settings : the screen brightness settings and backlight keyboard are missing from "Sound and Media" shortcuts menu.

I've just upgraded to Ubuntu Studio 26.04.

This has happened twice in the last couple of days: I plug in an external drive (ntfs formatted, I know I know, I promise, my next backup hard drive, I will reformat it to exfat or something), get some files off of it, and then try to eject the drive. At this point, it says that some processes are keeping the drive busy. The list of processes seems all related to glycin.

At this point, if I can manage to kill those processes, I might be able to eject the disk cleanly, but if I can't kill them, then the disk remains stuck. This gets nasty because the Ubuntu NTFS module is very sensitive to the volume's dirty flag, and refuses to mount the disk if the flag isn't what it expects, so then I have a borked disk until I can find a Windows machine and chkdsk it.

How to prevent this? I can't afford to bork my backup hard drive a few times a month because some new image loading framework has to thumbnail everything on a 2TB drive. (I guess that's what it is.)

There must be a way to configure it not to do this for external drives?

Thunderbird on my Ubuntu 24.04 box stopped downloading messages from Yahoo on July 21, 2026. Thunderbird still works as normal on my iMac and Android phone. On Ubuntu when I open email it asks me for my Yahoo password. When I enter the password I get the following:

Failed to execute child process "gnome software" (no such file or directory)

I use vim in gnome-terminal a whole lot everyday, and that means of course that I use the Escape key a lot. Sometimes when I hit Escape to exit vim's input mode, the result instead is that Gnome suspends (locks?), requiring me to wake it up and give it my password to get back in. When I do get back in, it's both evident and unsurprising that vim had not received the \033 character because it remains in input mode. So I have to hit Escape a second time (and sometimes this one too gets captured and results in another screen lock). This happens maybe three or four times over the course of an 8–10-hour work day, apparently at random—I have not found any pattern to when or why.

I'm running Ubuntu 26.04 LTS on an Acer Aspire 5, but the same thing happened in 24.04 LTS.

It seems to me most likely that I have an unfortunate setting for some Gnome configuration, but when I search for either "escape" or "ESC" within "Keyboard Shortcuts" in the Settings app, I find only these three entries:

Besides, a hypothetical conflict with some rogue key binding doesn't go very far in explaining why the undesirable behavior (locking Gnome) is intermittent.

Per this post, I also looked at the settings in gnome-terminal's main menu and found nothing bound to Escape.

What's causing this problem, and what are some fixes?

I want to check which Cyrillic LaTeX fonts are installed on my computer.
I tried to compile an LaTeX file, which I had in an old computer, and could compile on that old computer. But when I try compile it on my newer computer I got following messages

Missing character: There is no е ("435) in font larm1200!

Missing character: There is no т ("442) in font larm1200!

Missing character: There is no ы ("44B) in font larm1200!

           ............

With other word, one such a line for every letter.

Thanks for answer!

Running lsusb I get this output:

Bus 005 Device 002: ID 2808:c652 FocalTech FocalTech Fingerprint Device

The fingerprint option is not available in settings so I'm sure this is a missing driver issue.

I'm a linux newbie so any help in getting the fingerprint scanner to work would be super helpful!

I'm running Ubuntu 26.04, Nvidia GPU.

Occasionally, but not always, when I wake the machine from suspend, the mouse cursor is frozen. Everything else works - I can use the keyboard to navigate. It seems like it's losing the USB connection to my mouse. If I reboot the PC, it comes back.

I tried the method of going to my TTY session (Ctrl-Alt-F3) and then back to GUI, but that doesn't seem to wake the mouse.

Do you have any ideas?

This didn't happen when running under Windows, so I don't think it's a problem with the mouse specifically. It seems like Ubuntu is putting the USB devices in some sort of sleep state when suspended, but not waking the mouse when resuming. I don't know enough to confirm or diagnose that, though! I'm pretty new to this operating system.

Brand new installation of 26.04 on a Lenovo laptop, and I'm looking at some old files in Nautilus - this is the list view:

In grid view, the icon size fits when at next-to-biggest zoom level, but the icons don't change size when adjusting zoom level. This is the smallest zoom level:

As can be seen, these are all .img-files - in other directories I have the same problem with .fits-files.

So I thought maybe it's just unknown files - but I tried creating files e.g. asdf.qgtzx and they zoom nicely.

What's going on here?

My system does not finish the normal boot sequence after updating to the kernel version 7.0.0-29.

The boot screen will show the grub list and boot using the default option after the timer expires but does not get to the login screen. It does bot throw any errors when trying to boot like this.

When I select the recovery option using the same kernel version, it does boot all the way to the login screen but it does show the following error just before the boot sequence starts:

EFI stub: WARNING: failed to measure data for event 1: 08000000000000000b

I have installed the boot repair tool and created a BootInfo summary linked here

I am relatively new on Linux and I am not sure how to resolve this issue.

I would highly appreciate any pointers.

I've been running Ubuntu for about two weeks now. At first it was fine, but then I upgraded Ubuntu to the newest version, and now the brightness is super dark on the laptop and it can't be fixed. My Dell is a Latitude 7300. I reinstalled the original version I had again, but I noticed it has some old video codecs and it wasn't playing videos from my Jellyfin server properly.

Is there any fix for this? I'm finally getting used to the user interface, so I don't want to go back to using Windows unless I really have to. Also this tagging system is silly. It's almost like you don't want feedback.

I am running Ubuntu 26.04 on a Ryzen 5 on a Gigabyte Aorus Elite AX V2 motherboard.

This morning, my sound does not work. It worked fine yesterday, but not today.

On the settings page, under "Sound" it shows no input or output devices.

I wanted to try it on a USB stick, but the system is not recognizing them at this moment. That happens occasionally, so I am not concerned.

From another post I see that this was requested, so I will include that:

Possibly of some help is the fact that the output on the "Simple Wireplumber GUI" is blank under each of the headings. Is that possibly an indication?

I am led to believe this should help if the problem is in "Pipewire"

I have just looked at Pulseaudio volume and that is being refused. It's probably a redundant comment, but that is news to me.

Having turned off the computer for an hour, I notice it is not recognizing my USB sticks either. Once in a while that is the case, but repeatedly in short succession is distinctly odd. I am going to GParted to see if it is recognized there. I am assuming that it is not. That might be a further indication of the problem.

Twice now when I boot, enter my passphrase to decrypt my drive (before entering my regular user password) it take a long time, problem, then I get the following (see image above??) (also when I power off, then turn the power back on and boot).

The strange thing is that the second time I reboot (after I select the first option "Ubuntu" from the black and white reboot screen), it boots normally without errors and all my disks/data/folders/files appear to be OK.

I am not sure what the issue may be, and whether this will increase in terms of problems. I am a relative neophyte about Ubuntu, but I know how to enter commands to check things and the like. What can I do to resolve this issue?

My system: Ubuntu 25.10 on a Lenovo IdeaCentre AIO 27IRH9, 64-bit OS, Kernel version: Linux 6.17.0-41-generic

Extra note: I've booted a few times since getting this error yesterday and the day before, and it seems better as I didn't again get the boot error. But I am still not sure whether I should do something regarding this issue.

On an 8TB external HDD, I created an encrypted partition using cryptsetup:

sudo cryptsetup luksFormat /dev/sdX
sudo cryptsetup open /dev/sdX encrypted_drive
sudo mkfs.ext4 /dev/mapper/encrypted_drive

I am wondering why the partition created on the disk is not bigger than 2TB?!

I have tried to expand/enlarge the partition, but I had no success.

crypsetup version is: 2:2.7.0-1ubuntu4.2 ubuntu: 6.8.0-137-generic (ubuntu installed on a lattePanda single Board Computer)

Oldfred appears to be right: it seems that my partition table is msdos...

I tried to install some third party app, but installation failed. Now I got this annoying message. How can I get rid of it? I don't need the app anyway, I found a better alternative. terminal screenshot

I found the file mentioned in the error msg and tried to delete it, but it's write protected and I'm not sure how to change permission or ownership safely. (Last time I tried anything like that I ended up with a complete mess and a reinstallation of Ubuntu). I'd be thankful for any help!

Anyway, since sudo add-apt-repository ppa:atareao/atareao was the command I used for install, now I did sudo add-apt-repository --remove ppa:atareao/atareao

The result:

How to install gimp-plugins-gmic from snap and use it in gimp?

I am a complete noob and my WiFi suddenly stopped working. I'm on a framework 12, Kubuntu 26.04 and I've been using it pretty much problem free for a few months. Just today, the download speed on my network is stuttery and insanely slow, absolute highest at 1kb/s, lowest at 0, average blips are around 80b/s. WiFi signal is strong and works completely fine on other devices. Tried switching to my phone's hotspot: same result. Happened before and after upgrading to 26.04. Checked drivers, says they are all up to date.

Since I know literally nothing please let me know what more info you need to diagnose the problem, please and thank you. I'm at my wits end :(

Since buying a new Ubuntu 26.04 LTS laptop I find that I cannot record a video online. At first I could not record videos for longer than 1 second, now I have got it to record video but there is no sound. I have tried VokscreenNG, Simple Screen Recorder, Kooha and the built-in system but nothing works. This is most annoying as I do a lot of online recording and now nothing. I wish I hadn't upgraded my system to 26.04, 22 was much easier. But please can anyone help with this basic requirement for screen recorders when using Wayland. It will be much appreciated for the whole community going by the other requests for similar problems. My laptop is a Star Labs StarBook Horizon with built-in 26.04. The systems I'm using to try to record are: The built-in screen recorder that came installed (but which only records video); VokoscreenNG (which only records sound); Simple Screen Recorder (which also only records sound); and Kooha (which is the same). I have installed OBS Studio but that seems to be very complicated and more for video editing. I do not have an external microphone connected as I only want to record what is on the screen. I am a 74 year old and not too techy.

Ubuntu 26.04 LTS MS Surface Pro 4 laptop

I have followed the install process for the kernel at least 3 times not it does not appear in the Advanced Options.

I am just about to give up. Does anyone have a solution?

Installation process:

Debian / Ubuntu

First you need to import the keys we use to sign packages.

wget -qO - https://raw.githubusercontent.com/linux-surface/linux-surface/master/pkg/keys/surface.asc
| gpg --dearmor | sudo dd of=/etc/apt/trusted.gpg.d/linux-surface.gpg

After this you can add the repository configuration and update APT.

echo "deb [arch=amd64] https://pkg.surfacelinux.com/debian release main"
| sudo tee /etc/apt/sources.list.d/linux-surface.list

sudo apt update

If you encounter any issues reading "Error 401 Unauthorized" during the update or the installation below, please have a look at this.

Now you can install the linux-surface kernel and its dependencies.

sudo apt install linux-image-surface linux-headers-surface libwacom-surface iptsd

Ubuntu 26.04: Due to a bug, don't install libwacom-surface.

Important: Support for iptsd only goes back to the latest LTS release at the time of writing (Debian 11 and Ubuntu 22.04). If you are using an older release, and the above command fails, then please remove iptsd from it. You will still be able to use basic singletouch through the kernel driver, but multitouch and the stylus will not work.

After that you can install our secureboot key. This will import the key that the linux-surface kernel is signed with into your bootloader, so that the kernel is bootable without disabling secureboot.

sudo apt install linux-surface-secureboot-mok

This package will print instructions to the terminal. In case you missed those, it will ask you to reboot. Then, upon reboot, a blue menu (MokManager) should pop up, asking you whether you want to enroll the key. You need to interact with the menu and select "Enroll" to proceed. Confirm with ok/yes and when asked for a password enter surface. Note that MokManager expects a QWERTY keyboard layout, you may need to adjust your input accordingly. In case you missed the menu or accidentally chose the wrong options, you can uninstall (fully) and then reinstall the package and reboot to trigger the menu again.

Note that this will only work if your Debian derivative supports secure boot out-of-the-box. If if not, please consult the wiki of your distribution and set up secure boot for distro/stock kernels first. You also want to skip installing the package for now and only install it after you have set this up.

The linux-surface kernel will be installed alongside the default kernel provided by the distribution. This way you have a backup kernel you can use if something goes wrong. The bootloader will pick up the kernel by default, but you should update its configuration to make sure it was recognized.

sudo update-grub

Finally, reboot your system and you should boot into the linux-surface kernel. Please make sure you are actually using the right kernel by checking if the output of uname -a contains the string surface. If it doesn't contain that string, you are still using the default kernel and need to configure your bootloader.

The kernel does not appear in the advanced options in the grub menu.

I've been trying to get my UB600 Bluetooth dongle to work, however it seems that it's not compatible out of the box. In fact, there's only 1 place with a solution how to get it to work however it seems the explanation on how to do it goes over my head. I've tried using what they gave me in konsole but some things just error and I can't seem to get around that. The fix I've been attempting is this. The issue I'm having is, it detects the Bluetooth dongle, but the computer is then unable to detect any Bluetooth devices at all. The lsusb is exactly as shown on that link as is the journalctl.

Is there any chance somebody could explain to me like I'm a 5 year old how to apply that patch, or better yet, create a solution for me? I am running Kubuntu 26.04 on kernel 7.0.0-27-27.

Edit: Following "david" in the comments advice results.

I'm looking for a reliable WhatsApp client that works well on Ubuntu 24.04 LTS. Ideally, the client should have:

• Desktop notifications that integrate properly with Ubuntu’s notification system
• Autostart on login, so I don't miss any messages or notifications
• (Optional but preferred): Support for video and/or voice calls

How to set this up?

I had the 24.04 upgrade fail on me. :(

My attempts to "fix" the broken apt have left me with a system that no longer boots.

So I've downloaded the Desktop distro, made a bootable USB, and am trying to re-install without losing my data. From what I've read online I think this "should" be possible...

But when I get to the "Manual partitioning" screen during the setup process I cannot specify my root partition (which also has all my user data on...) without the Format checkbox becoming ticked, and I cannot then untick it.

Please can anyone help me?

Recently I have switched from Ubuntu 18.04 to Ubuntu 22.04. One of my external hard disks, a Western Digital Elements 3 TB hard disk, which has always mounted properly in 18.04, did mount and worked properly for a few days in 22.04. Then it stopped working because it became impossible to mount it. When using it with another computer under Windows 11, it mounts and works properly. The error message in Ubuntu 22.04:

Unable to access "Elements". 
Error mounting /dev/sdi1 at /media/lubomir/Elements1: Unknown error when mounting /dev/sdi1

Please help me to resolve this.

This is my second attempt to migrate to Ubuntu 22.04. Everything is fine, but I am missing a tool for downloading videos from the internet.

I am looking for an app with a graphical user interface that allows me to download videos from websites.

I tried on ubuntu 16.04 and 20.04, however I cannot install dnsmasq.

The error I get is:

Package dnsmasq is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  dnsmasq-base

E: Package 'dnsmasq' has no installation candidate

Is this no longer a package available on ubuntu repos?

According to the link. https://www.howtoinstall.me/ubuntu/18-04/avahi-daemon/

The method it provides for installing mDNS consists of just two lines of command:

sudo apt update
sudo apt install avahi-daemon

According to the link: What is mDNS? Is it possible to make mDNS query without mdns service running?

One friend replied:

Ubuntu systems just need avahi-daemon and libnss-mdns installed.

So the first question is :

What is the standard method for installing mDNS on ubuntu 18.04?

The second question is:

After installing mDNS, how should I configure mDNS?

The third question is:

How can I verify the functionality of mDNS?

I want help to

• make Ubuntu 'update && upgrade' itself automatically,
• select the settings for this automatic system.

How can I do it? Please advice about

• where to find the menu (GUI) or file (command line) to do it,
• what settings that can be recommended (if different from the default).

As a bonus, please describe how different types of program packages are treated,

• program packages from Ubuntu repositories and PPAs
• snap packages
• flatpak packages
• other kinds of programs/packages.

I have a Brother MFC-J470DW printer that I have connected to a Linux desktop (running Ubuntu 14.04) using a wireless router network. The printer works fine for printing and copying, but now I want to add the scan function.

To set up the scan function, I went to the Brother web page Downloads for this printer:

and under Scanner Drivers selected "Scanner driver 64bit (deb package)", "Scan-key-tool 64bit (deb package)", and "Scanner Setting file (deb package)". For each package, I accepted the EULA, and selected "open with Ubuntu Software Center". Then after the USC window pops up, I click on Install and the red line goes from left to right. In each case, the USC window then had a green check mark and the Install box changes to Reinstall (that's how you know it worked).

So now I try it out. Hitting the Scan button on the printer, selecting "Scan to file", and hitting OK produces the message "Check Connection".

I checked the Brother Linux Information FAQ (scanner) page and the 14th question seems the same as mine:

    When I try to use the scan key on my network connected
    machine, I receive the error "Check connection" or I can not
    select anything except "scan to FTP".

I explored the solution given for this FAQ, but found from ifconfig that I am already using eth0, the default setting, so presumably that is not the problem.

I also found brscan-skey installed in /usr/bin and did

drrm@drrmlinux2:~$ brscan-skey -t
drrm@drrmlinux2:~$ brscan-skey

but that didn't help - I still get the "Check connection" message.

What can you suggest to fix this problem?

Brother released an upgrade for scan driver dated 05/06/2014. I installed, but still get the "Check Connection" message. On the downloads page (deb version), they also still state the release date as 12/03/2014 for the scan-key-tool 64-bit and scanner settings file packages, which has not changed. So maybe I just have to wait some months to see if the release date of these other packages changes.

I am trying to install dssp on ubuntu 12.04. I am new to ubuntu. I tried this

sudo apt-get install dssp

Please give suggestions.
