After updating the Firefox snap to 149, it seems to hang on startup. It'll just open a blank window and then stop. The only way I've managed to fix it is starting it in safe mode and disabling hardware acceleration. After that, it'll start fine, albeit with degraded performance.

Since it's probably relevant, my GPU is a Nvidia 1080Ti with driver 580.126.09.

How can I set fractional scaling of 125% on SDDM and also have the cursor scaled as well?

Im also looking for a way to hide the clock from both lockscreen and sddm. Im using the Breeze theme

Deja Dup failed to connect a remote FTP server where it sends my backups. Last backup was 7 days ago. The error message is as below: "Error: Cannot open data connection. Maybe your firewall prevents this?".

I have never made any changes to the firewall settings, so the issue is somewhere else. I have checked the username/password in Seahorse and they are correct. I can connect to the remote server and browse around with Filezilla. I can also connect with the command line but I cannot browse around. The error message is "Passive mode address mismatch".

I suspect the ftp command line is having the same issue as Deja Dup. Any idea how I can resolve this ?

Only noticeable change last week is I've set up 2 VPN connections in Network Manager (OpenVPN and WireGuard). Not sure if they are to blame, but everything else works whether the VPN is on/off (regardless if I use OpenVPN or WireGuard). Deja dup and the ftp command fail as above with/without VPN.

I have also noticed that the IP mentioned on the PASV command (see image above -> XXX.XXX.18.28) differs from the one I get if I ping the server (XXX.XXX.18.68). Could be wrong but I suspect I need to force the ftp client to resolve the correct address before sending the command, but I have no idea how to do so for either ftp command line or Deja Dup.

I have tried forcing active mode (ftp -A) passive mode (ftp -p) and IPv4 only (ftp -4), with no luck. According to Murphy's law, I am due an HDD failure v soon, so I really hope someone can help fixing this before it happens.

I am relative new to Linux and have install Ubuntu 24.04.4 LTS on my HP Victus 15 fb3022no laptop.

The problem is that the computer freezes i random intervals - at least I have not found a pattern. It is often under low workload, eg browsing with the Vivaldi browser.

As I understand the problem from other posts it is relatet to the onbord CPU/GPU AMD Ryzen AI 7.

Solutions that I have tried without it working: Hardware acceleration disabled in Vivaldi.

PSR (Panel Self Refresh) disabled by adding the following parameter to my kernel command line: amdgpu.dcdebugmask=0x12

• from Awnser no 2 in this thred: Ubuntu 24.04 freezing with AI 9 HX 370

cat /proc/cmdline

Gives this result: " BOOT_IMAGE=/boot/vmlinuz-6.17.0-19-generic root=UUID=35bedf7b-bdb8-4c6f-83b7-44dc3d7467cb ro quiet splash amdgpu.dcdebugmask=0x12 vt.handoff=7 "

Have I done disabled the PSR right?

Weary briefly under boot I see this message:

RDSEED32 is broken. Disabling the corresponding CPUID bit.

Seeing other post I get the impression that it is not important - but is that also the case for me?

I appreciate any help to solve the problem, and pleace let me know if there is any information that you need to understand the problem.

I have set up Ubuntu on ZFS under LUKS as described here. However, I have used Ubuntu 24.04 instead of 22.10. This seems to work just fine, except for one thing: Directly after installation, on the first login, I get a "Ubuntu 24.04 has experienced an internal error" dialog box:

Ubuntu 24.04 has experienced an internal error

Excetutable Path: /usr/share/ibus-table/engine/main.py

There may be typos in the traceback because I had to copy it from a screenshot. Note that username is the literal string username and not something I substituted for my actual username. If this is python, I would expect it to contain the actual path. Of course, there is no user named "username" on my PC. (Maybe there is some substituion of the exception message going on, but I think that's unlikely. perhaps for anonymization purposes?)

This error keeps appearing and does not disappear after a reboot. The error persistently appears and after clicking the window away, it just re-appears, often several times. I have checked the permissions on my home directory and it is 755, owned by me and my group. Strangely, after some time and some reboots this error seems to disappear. I am not sure if this actually solves it.

I think on a previous installation I created a fake home directory for "username" with 777 permissions, but I do not think this solved the issue.

What is the actual way to fix this?

I'm trying to work out why my wifi network has all of a sudden disappeared from the network list, the wifi is fully functional and appears on all of my other devices. Using Ubuntu 24.04.4 LTS, Broadcom b43

any ideas?

[SOLVED]: See comment from @DanielT.

I was playing around with KolourPaint and I managed to undock the Colors panel. Never found how to dock it back.

I have Kubuntu 24.04 with KDE Plasma 5.27.12.

I have an ASUS TUF F15 FX506LH laptop, and I’ve disconnected the battery because I’m running Linux—Ubuntu 24.04.4 LTS. On Windows 11, I used MyASUS to set the battery to 60% to extend its life. The problem is when I enter my user password to log into Linux: I can’t type anything at all on the keyboard when I first open it. I have to restart the laptop to be able to type on the keyboard and log in. What can I do to fix this problem?

I'm using Ubuntu 22.04 and I usually use OpenVPN for gaming, but it's stopped working. It just keeps loading for a few minutes and then says "connection failed." I tried to fix it for a few hours with solutions I found in some posts, but none of them worked. Image showing NetworkManager notification error.

i installed Ubuntu 24.04.4 LTS on a laptop and when i install steam games for some reason it adds like 40ish shortcuts so when i look in the apps all my games have 40ish. I would like to be able to just have 1 of each or none would even work as i can launch though steam.

I'm using Ubuntu 24.04. I am trying to pipe a stream to VLC. When it was rtmp I could do it, but I'm having trouble with hls/m3u8. An example link (https://ppv.to/live/247-family-guy). I have tried searching the network console in Firefox, but I couldn't find the master URL. video downloadhelper extension is able to download the stream, so I should be able to pipe it to VLC, right?

I have found the master URL, though I'm receiving a 403 Forbidden error. Why can the extension download the stream, but ffmpeg and yt-dlp can't?

I believe the answer is missing http headers. I have tried adding some that I know (user-agent, origin, referrer), but I'm still having no luck. Does anyone know how to find which headers are missing?

I'm using a script I modified from here to change my wallpaper(and in-terminal colors to match). It works when I run it from the command line, but not when I use crontab trying to make it run automatically.

crontab that's not working:

SHELL=/bin/bash
* * * * * /home/drift/custom-scripts/dynamicWallpaper -p /home/drift/Pictures/Wallpapers --wal
* * * * * /home/drift/custom-scripts/testing-feh
@reboot sleep 30 && /home/drift/custom-scripts/dynamicWallpaper --wal
#Back In Time system entry, this will be edited by the gui:

(note the newline at the end)

After a lot of troubleshooting, I think this is failing because of one of 3 issues:

• feh isn't working correctly, which would be a big problem, because ubuntu 25.10 is lacking support to replace it(not supporting X11 anymore). I could switch over to another desktop environment, but not without losing all of the setup I've put into this one (correct me if I'm wrong)

• cron isn't working correctly, which would also be a big problem. I'm aware I can run it as a systemd service(in theory--more on that later) but the backup app I use, Back in Time, uses cron as well, and I need that to work.

• I somehow haven't given correct permissions to some file or other?

It might be something else as well, because there's another script that I can't run automatically no matter how hard I try. I'm trying to focus on one problem at a time so I haven't looked into it nearly as much, but it's worth mentioning that this second script also didn't run automatically as a systemd service.

Things I've tried:

• the entire damn list under Why crontab scripts are not working?, not joking or exaggerating

• rebuilding the script line by line and seeing where it fails, which is pretty much instantly, and it gives the error:

  (process:65604): dconf-WARNING **: 02:26:01.922: failed to commit changes=
  to dconf: Cannot autolaunch D-Bus without X11 $DISPLAY
  feh ERROR: Can't open X display. It *is* running, yeah?
  

  Then when I provide the display either at the top of the script or in cron itself, it gives me this error instead:

  xrdb: Resource temporarily unavailable
  xrdb: Can't open display ':0'
  

  which is what made me think it's a wayland issue. I messed around with environmental variables a lot before I found the post about X11 not being supported.

• editing my bashrc with paths (every time something failed to work I removed it again, so it should be back to default state now)

• went through my entire journalctl from reboot to see if cron runs. Yes it does, and it runs the commands seemingly fine. Notable code:

  Mar 19 02:13:11 DriftPC (cron)[2105]: cron.service: Referenced but unset environment variable evaluates to an empty string: EXTRA_OPTS
  Mar 19 02:13:11 DriftPC cron[2105]: (CRON) INFO (pidfile fd = 3)
  Mar 19 02:13:11 DriftPC cron[2105]: (CRON) INFO (Running @reboot jobs)
  Mar 19 02:13:11 DriftPC CRON[2110]: pam_unix(cron:session): session opened for user drift(uid=1000) by drift(uid=0)
  Mar 19 02:13:11 DriftPC CRON[2111]: pam_unix(cron:session): session opened for user drift(uid=1000) by drift(uid=0)
  Mar 19 02:13:11 DriftPC CRON[2128]: (drift) CMD (dynamicWallpaper --wal)
  Mar 19 02:13:11 DriftPC CRON[2129]: (drift) CMD (/home/drift/custom-scripts/audio-hallelujah.sh)
  Mar 19 02:13:11 DriftPC CRON[2110]: pam_unix(cron:session): session closed for user drift
  

  Note that the cron commands were later edited to include the full path and no periods and a sleep command beforehand, and testing that achieved the same result. Later removed the script audio-hallelujah from crontab to try it as a systemd service instead, which as mentioned also didn't work.

Notably, the full script's --wal does work. Whenever the full script runs through cron, it changes my terminal font colors. _{(25.10 has Ptyxis as a terminal and I can not find a way to get the background to change too, so I've just accepted it)}

Again, it's working fine when I run it as dynamicWallpaper from the terminal. The issue is to make it run automatically at specified intervals.

For some days or weeks my chrome changed behavior to the worse.

When I click on a link in my Thunderbird (or in a PDF file or just opening a HTML file), chrome opens this in the worst possible window (a window which is even on another workspace).

Earlier chrome always chose the last active window, which is my wanted behavior. Now it seems that it always opens it in "window no. 1"

Since I always have several windows open scattered over different workspaces, this is really annoying.

Is there any workaround to restore the old behavior?

Chrome: Version 146.0.7680.80 OS: Ubuntu 22.04.5 LTS, MATE 1.26.0

Recently, I noticed this very strange issue with sound and video playback in Ubuntu 24.04 with kernel Linux 6.8.0-57-lowlatency #59.1-Ubuntu SMP PREEMPT_DYNAMIC on a Dell XPS Laptop: When HDMI and earphones are not connected, it cannot output sound. I still can set the sound level in the top right corner, but it does not make any sound. In the system settings, Ubuntu lists "no output devices" in the playback category. Cable-bound earphones and HDMI do not show this issue.

Another, possibly related issue: Video playback on YouTube hangs after just a second indefinitely. It looks like it has to load the video, but the timeline already indicates that a good chunk of the video has been loaded. I can solve this problem temporarily by restarting the Pipewire service with systemctl --user restart pipewire, but it will re-appear later - either when starting another video or after waking up from standby. Strange: playback of mp4 files with mpv and vlc work fine.

Yet another, possibly related issue: When connecting my Bluetooth earphones, it shows them as "connected" for about a second, then immediately disconnects them again. The earphones don't notice a connection. Of course, no sound output. I already have had an issue with Bluetooth earphones and tried its solution, but to no avail.

These problems all have something to do with sound/media playback and I noticed them at around the same time, so I believe, they may be related. Except for regular updates, I haven't changed my audio stack on my system and I believe this problem started after having installed the video conferencing software WebEx.

Of course, I already applied the newest updates, tried to restart the computer, and uninstalled WebEx. Restarting Pipewire does not work, nor restarting pulseaudio, nor does reinstalling and reloading the bluetooth module of pulseaudio.

pactl load-module module-detect, as suggested here printed 23 and it gave me two sound devices: Built-in sound output device and Speakers, of which the first one is selected. When I select "Speakers", it re-activates the sound. However,

all sound works fine until I reboot again. I have to run the pactl command every time after a reboot.

is not very ideal. Something is still broken. It also does only solve the sound problem temporarily, not the video playback and bluetooth phones problem.

How to solve this issue?

Update: I found that pulseaudio and pipewire are installed and running on my computer and pipewire-pulseaudio was listed in apt as 'configuration required'. After uninstalling pulseaudio and re-installing pipewire-pulseaudio together with other packages, such as pipewire-audio and now, video playback works, but no sound output whatsoever - neither via cable earphones, speakers or HDMI. Also the bluetooth headphones continue to be automatically disconnected after a second.

Update 2: Since I couldn't find a better solution and limited available time, I decided to reset my system to an older state with TimeShift. Everything is working now.

When I reinstalled the OS, I had only one, Ubuntu 22.04 Gnome desktop, option. I got used to MATE desktop. Therefore I installed MATE desktop too. Having two desktop environments, MATE & Gnome, how to switch between them? I cannot just remove Gnome as it affects LibreOffice. Do you have any suggestions?

I want to install Python 3.9 on my Ubuntu 20.04, and all tutorials I can find include a step as follows:

sudo add-apt-repository ppa:deadsnakes/ppa

I am concerned about security. I've looked into this question: Are PPAs safe to add to my system and what are some "red flags" to watch out for?

According to the answers, some of the main points to consider are:

• Who made the PPA
  • Someone named deadsnakes, apparently, but what can I conclude from this?
• How many users have used the PPA
  • Where to get this information? Someone asked this in a comment 9 years ago but it wasn't responded.

Attempts to search the internet for deadsnakes only brought me into tutorials on how to install Python, which is where I started...

• System: Ubuntu 18.04
• Webcam: Logitech C920 / C922

I use mostly the Microsoft Teams Ubuntu app (v1.4) to join work video calls. I also make Zoom and Meet work video calls on occasion.

The webcam resolution during Microsoft Teams (and also Zoom and Meet) work video calls seems to be something like 16:9, which shows a lot more of my (messy working from home) background than I want.

I would like to set the aspect ratio as 4:3 and zoom in a bit so that my profile is centred on the screen. How can I do this in Ubuntu?

I installed V4L2 Test Bench from Ubuntu software and this allows me to set the aspect ratio for video within that app, but these settings do not apply to the video conferencing apps.

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 couldn't install my VMware on Ubuntu. Whenever I execute sudo vmware, I receive a popup asking me to choose the version of gcc. However, unlike other errors similar to this, I am faced to choose a gcc version(null). Can you please help me out?

Tried but failed:

■ I tried mentioning the path as,

• /usr/bin/gcc 
• /usr/bin/gcc-9
• /usr/bin/gcc-10

■ tried updating linux-headers

Note: I currently have gcc version 10 and 9 installed.

Here is the popup message showing error

I am having these "psmouse" errors

$ dmesg | grep -i psmouse

[   13.463294] psmouse serio1: Failed to deactivate mouse on isa0060/serio1: -5

[   18.454190] psmouse serio1: Failed to enable mouse on isa0060/serio1

I do not know how to disable/blacklist this psmouse and how to fix this error because when I power off my laptop this error gets a lot of time to vanish (or the error itself or a blinking dash).

I am on a Dell XPS 15 7590 runnnig Ubuntu 20.04 on 5.4 kernel.

After a day of restarting my computer i finally given up. I had Ubuntu 18.10 installed and worked perfectly and then i got the upgrade prompt and upgraded to 19.04. The upgrade crashed and after that the system was still booting except 80% of the time. Most of the boots resulted in a purple screen and that is all. I tried everything on the web and nothing seams to work. It is very very random. Couldn't find a way to see where it hangs. The frozen boots fo not appear in the journal. If i try to boot the recovery both messages appear so loads the kernel and the other thing and then it hangs. I reinstalled Ubuntu 18.10 (with updates) and had the same problem. I did the upgrade (which this time worked) to 19.04 and same problem. Now I installed Ubuntu 18.04.2 without any updates and i got it working 4/4 boots. I did the updates 400ish mb of updates and then started doing the same thing with the purple screen. I reinstalled the 18.04.2 and didn't do the updates.

I have no other options than to hope.. I have a Zenbook UX433FA and dualboot with Windows. I guess it is one of the packages that gets updated on 18.04.2 but i don't know which one.

Thank you.

edit: before the 18.10 reinstall i did a fresh reinstall of 19.04

I use Thunar instead of Nautilus on Ubuntu 18.04. This works fine, but any application still uses Nautilus instead of Thunar when saving/opening etc or when opening directories/mounted drives from the desktop.

I have already tried running:

xdg-mime default nemo.desktop inode/directory

This had no effect

That possible solution was from this thread:

https://askubuntu.com/a/1043504/953041

Can someone explain what this error means and how i can resolve it please?

So for some reason I haven't been able to open the terminal in ubuntu anymore, I already tried the solutions from these threads

Terminal does not start on Remote Desktop; how to fix it?

Can't open terminal in Ubuntu 18.04 after upgrade from 17.10

and none of them have worked for me.

With the solution where I need to run locale.gen,I kept getting an error that I did not have an application to open it properly, I then got prompted to downloaded the Games app but it couldn't open it either (wasn't surprised)

With the solutions where I'm being told to run some commands with the terminal, it's not possible as I can't even open the terminal (and I'm not to sure what the gnome terminal is, I tried searching for it on my system but it just led me back to the regular terminal)all I can do is press on the terminal icon and then nothing happens. I'm pretty new to using ubuntu so I was hoping I could find some help here. I am running ubuntu 18.04

thanks

I have a 1TB of harddrive on which windows 10 is installed. I previously had Ubuntu installed on the system but deleted it as I wanted to install the 14.04. I deleted the partition from Windows 10.

When I am trying to install using the live CD, I can only see the disk as a single drive and not seeing all the partitions. I am not sure what is wrong. Is it something related to my partitioning?

I need to use the J drive to install ubuntu 14.04 and I drive for 16.04.

I am new to linux and I have kubuntu 15.10. I connect to a internet network at my university which has proxy settings. So wanted to know how to make changes at the Kubuntu system level for this proxy.

I went to System Settings > Network > Proxy and in the available options, I chose the manual options (Use Manually Specified Proxy Configuration) and entered the appropriate values. [At the firefox side, I have set "Use System Proxy".] But this setting is not working. If I enter the appropriate values in the firefox network settings, I am able to connect to the internet.

Can someone please tell how to make system level proxy changes? And also, why the configuration I set at Network>Proxy>Manual Proxy does not work?

Thanks for your time!

After upgrade to 13.10 my bluetooth stoped to work: - I don't see bluetooth indicator at all - I am not able to turn it on and serch for devices

When I hover on tabs in chrome and scroll the mouse wheel, the tabs are changing focus. This feature is really annoying for me and i want to turn it off. Any ideas?

P.S. The way I usually close an opened tab is to hover the pointer over that tab and click the wheel (also known as middle button). This feature is kind of a convention and is available in many applications.

I'm looking to mirror my Ubuntu destop onto my TV by using my PS3. All done via wifi. Similar to the 'AirPlay Mirroring' in Mac OS X Mountain Lion. http://www.apple.com/macosx/mountain-lion/features.html#airplay

Is this possible? How would I go about it. To be clear, I don't want to share movies in particular, rather to send my screen exactly as I see it.

Is there a way to print the comments that are associated with a pdf on the linux version of Adobe Acrobat 9? Both acroread and evince display the comments just fine, however the linux version of the reader lacks the button in the print dialogue to enable printing comments.

Specifically I'm looking to recreate this feature (image taken from adobe.com) where the comments are printed on a seperate page with lines to the main document indicating where the comment was inserted.

Please Note: I am not asking to modify or write comments and annotations (typically a feature associated with Acrobat Pro), but to merely print them in a conveniently readable way.
