Firefox doesn't play embed mp4 https://askubuntu.com/questions/1568751/firefox-doesnt-play-embed-mp4

Recently installed Firefox (v. 153) doesn't play embed videos mp4. It shows this error:

no video with supported format and mime type found

ffmpeg is up to date, settings at firefox untouched. What should I do ?

Constant freezing with Ubuntu 26.04 install with AMD integrated graphics https://askubuntu.com/questions/1568749/constant-freezing-with-ubuntu-26-04-install-with-amd-integrated-graphics

I am trying to install Ubuntu 26.06 on a new PC with an AMD Ryzen 7 7700X. There is no dedicated GPU so I am using the integrated graphics.

At the login screen the screen goes black every few seconds. If it is enough time to log in, the screen goes black after a few seconds and I am back at the login screen.

The recurring error is:

amdgpu 0000:11:00.0: ring gfx_0.1.0 timeout, signaled seq=15, emitted seq=16 
amdgpu 0000:11:00.0: Process gnome-shell pid 10912 thread gnome-shel:cs0 pid 10209 amdgpu 0000:11:00.0: Starting gfx_0.1.0 ring reset 
amdgpu 0000:11:00.0: Ring gfx_0.1.0 reset failed 
amdgpu 0000:11:00.0: [drm] *ERROR* Failed to initialize parser -125!

Reading some related errors, I have tried a couple of things so far:

  1. Update the BIOS

  2. Run memtest -> 25 passes overnight all clear

  3. Change UMA Frame Buffer size to 2GB in the BIOS

  4. Tried regressing the kernel, but wasn't able to (only 7.x.x versions are listed by mainline:

    sudo mainline --install 6.12.0

    Kernel "6.12.0" not found

  5. Several grub settings

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.gfxoff=0 amdgpu.runpm=0 pcie_aspm=off"

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.dcdebugmask=0x10" GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.dcfeaturemask=0x2 amdgpu.ppfeaturemask=0xfffd7fff"

  6. And finally use a live USB to try Ubuntu 24.04, which also freezes immediately (no black screen but blurry display)

  7. Tried DP and HDMI cables.

The only think that works is to boot into save graphics or apply GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset", but it's not a long-term solution.

Any ideas for further troubleshooting? To me the issue seems to be the integrated graphics on the CPU, but could it be anything else?

Would greatly appreicate any suggestions!

Ubuntu 26.04 Stuck at full brightness https://askubuntu.com/questions/1568744/ubuntu-26-04-stuck-at-full-brightness

I have a Dell e7470 with 26.04 that is stuck at full brightness. Booting a live instance of 24.04 works properly. I just tried the 26.04 live instance and it works properly. There must have been an update that killed that feature but unsure where to check to fix it.

Also noticed that the laptop will not come out of suspend. Powers back up but no screen. I think this happened at the same time as the brightness issue.

Snap can find JetBrains snaps but cannot install or retrieve metadata (snap not found) https://askubuntu.com/questions/1568743/snap-can-find-jetbrains-snaps-but-cannot-install-or-retrieve-metadata-snap-not

Environment

  • Ubuntu 24.04.4 LTS (Noble)

  • Kernel: 7.0.0-28-generic

  • Architecture: amd64

  • snapd: 2.76.1

  • snap: 2.76.1

Problem Description

I encountered an inconsistent behavior with Snap.

The snap find and snap search commands successfully list JetBrains applications such as Rider, PyCharm, IntelliJ IDEA, RustRover, DataSpell, and GoLand.

However, every command that relies on retrieving snap metadata or downloading the package fails with "snap not found".

Examples:

$ snap find rider

Name   Version  Publisher   Notes    Summary
rider  2026.2   jetbrains✓  classic  The world's most loved .NET and game dev IDE

But:

$ snap info rider
error: no snap found for "rider"

$ sudo snap install rider --classic
error: snap "rider" not found

$ snap download rider
error: cannot download snap "rider": snap not found

The same behavior occurs for:

  • rider

  • pycharm

  • intellij-idea

  • rustrover

  • dataspell

Working Snaps

Snap itself appears to function correctly.

For example:

sudo snap install hello-world

installs successfully.

Previously installed snaps continue to work normally, including:

  • code

  • firefox

  • postman

  • brave

  • telegram-desktop

  • remmina

Connectivity Checks

Connectivity appears normal.

snap debug connectivity

returns

PASS

The Snap Store is reachable:

curl -I https://api.snapcraft.io

returns HTTP 200.

Additional Observation

Direct requests to the Snap Store return:

{
  "error-list": [
    {
      "code": "resource-not-found",
      "message": "No snap named 'rider' found in series '16'."
    }
  ]
}

while snap find rider still lists Rider normally.

This suggests that the search index and the metadata/download API are returning inconsistent results.

Expected Behavior

If snap find rider returns a valid snap, then:

  • snap info rider

  • snap install rider --classic

  • snap download rider

should all succeed.

Actual Behavior

Search succeeds, but metadata retrieval and installation fail with snap not found.

This appears to be an inconsistency between the Snap Store search index and the API used by snap info / snap install.

GNU tar `--one-top-level` now gives "Invalid cross-device link" error https://askubuntu.com/questions/1568742/gnu-tar-one-top-level-now-gives-invalid-cross-device-link-error

To extract an archive at a certain location (which may not exist yet), I like to use the --one-top-level option, e.g.

tar xzf ARCHIVE.tar.gz --one-top-level=/my/folder

This has always worked fine, but recently (looking at logs of docker build actions) it just produces errors:

tar: /my/folder: Cannot mkdir: Invalid cross-device link
tar: /my/folder/somefile: Cannot open: Invalid cross-device link

I can reproduce the error on my WSL installation, so it doesn't seem to be specific to the environment where I build docker containers. It started happening on July 7th, and happens Ubuntu 22.04, 24.04 and 26.04.

Did something change to tar or the one-top-level option? Currently running version `1.35+dfsg-4ubuntu0.4` on my WSL installation which is affected.

How to build a single absent in-tree kernel module with proper kernelrelease? https://askubuntu.com/questions/1568737/how-to-build-a-single-absent-in-tree-kernel-module-with-proper-kernelrelease

I am trying to add to my machine a 'missing' kernel module, which is in-tree, but not configured in the Ubuntu kernel builds, as discussed in this question.

I am mostly following the procedure outlined in this question and answer.

Specifically, I obtain the kernel source from the Ubuntu repository, and check out the tag relevant to my running kernel (7.0.0-28-generic)

$ git clone https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/noble
$ cd noble
$ git checkout Ubuntu-hwe-7.0-7.0.0-28.28_24.04.1

I then configure the build system

$ make oldconfig #Uses config from /boot/config-7.0.0-28-generic
$ sed -i 's/# CONFIG_MODULE is not set/CONFIG_MODULE=m/' .config #Enable the module I want to build
$ make scripts
$ make prepare
$ make modules_prepare #Select relevant driver modules with 'm' when prompted
$ cp /usr/src/linux-headers-$(uname -r)/Module.symvers . #Copy the current kernel's Module.symvers, to avoid rebuilding the entire kernel for generation

and build the driver modules

$ make M=drivers/<module>

Now at this point, I could, in principle, add the modules using insmod. However, because I'm building several modules with a dependency tree, I'd like to install them to /lib/modules/7.0.0-28-generic/updates for use with modprobe. However, running make M=drivers/<module> modules_install installs my newly-built modules in /lib/modules/7.0.12+/updates instead.

This makes some degree of sense, as make kernelrelease returns 7.0.12+ rather than the expected 7.0.0-28-generic. Since this kernelrelease number is embedded into the module as well, a manual copying to the normal install location will still pose issues for the use of modprobe, as discussed here.

The main question is: what needs to change in my workflow to produce the expected kernelrelease value, and allow installation and modprobe use. The proposed solution on unix.se above doesn't seem to apply in this case, unless I am misunderstanding.

Happy to share the exact module(s) I am trying to build if that is relevant. As far as I can tell, this is not related to the issue I'm having, and I figure a generic solution will be more applicable to others.

I have a fresh install of Kubuntu 26.04 on my MSI Katana 15 HX B14WFK laptop, installed with dual booting with Windows 11. While on Windows my fans work fine, on Linux my laptop overheats frequently, the following output of sudo sensors reveals why:

It appears only fan1 is working for some reason. I tried installing fancontrol but it requires pmwconfig to work correctly, which gives me the following output:

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

I tried troubleshooting this problem and online I found that adding the line acpi_enforce_resources=lax to /etc/default/grub might solve the problem but it did not help.

I also attach the output of sensors-detect:

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): YES

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): YES
/dev/port: Operation not permitted

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): yes
/dev/port: Operation not permitted

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)yes
Successful!

Monitoring programs won't work until the needed modules are
loaded. You may want to run '/etc/init.d/kmod start'
to load them.

Unloading cpuid... OK

This changes nothing. Online I have seen that solutions are motherboard-specific, but no online solution I could find for MSI laptops helped.

Is anybody able to help? Thank you in advance!

And after that I reboot. Everything seems in order, when I go to edit my preferences for the driver in /sys/devices/platform/msi-ec the folder isn't there.

I also tried installing MControlCenter for a GUI version of the program, but it claims msi-ec is not installed.

Does anybody know if anything went wrong in the installation of the driver? Thank you!

the result is partially correct. Some correct answers are missing.

Thanks in advance for any insight you can provide.

BTW, the lazy-match capture group returns too much in several circumstances. GNU sed 4.9.

Changing auto-login user on Kubuntu 26.04 https://askubuntu.com/questions/1568691/changing-auto-login-user-on-kubuntu-26-04

I recently installed Kubuntu 26.04 on my Framework 16 laptop. When I installed Kubuntu, I created a user, foo, and set it to log in automatically on boot. Since then, I have created another user, bar. (Both foo and bar are administrative users.)

I would now like bar to be the user which is logged in automatically on boot, rather than foo. However, I can't find any way to change this. This article says to go to the "Startup and Shutdown" item in the left sidebar of System Settings. However, on my computer, there is no "Startup and Shutdown" item present in the left sidebar:

System Settings - first half

System Settings - second half

I've looked at other items that seem promising, such as "Screen Locking", "Users", "Autostart", and "Session", but none of them have a way to change the auto-login behavior.

How can I change it to log in "bar" instead of "foo"?

Why can't I adjust brightness https://askubuntu.com/questions/1568686/why-cant-i-adjust-brightness

Iam new to linux Ubuntu and it is my first day , iam not able to adjust brightness at all .. Please anyone help me out . I have acer aspire 7 laptop and the version is ubuntu 26.04. When use fn key to increase or decrease brightness then that animation thing happens but brightness doesn't increase or decrease.

I need help with support for TP-Link UB600 Bluetooth Dongle on Kubuntu 26.04 please https://askubuntu.com/questions/1568248/i-need-help-with-support-for-tp-link-ub600-bluetooth-dongle-on-kubuntu-26-04-ple

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.

Results of lsusb | grep -i 'tp-link':

Bus 001 Device 012: ID 37ad:0600  TP-Link Bluetooth USB Adapter

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.

Drawing tablet not working properly - pointer shows https://askubuntu.com/questions/1567564/drawing-tablet-not-working-properly-pointer-shows

I just installed Ubuntu 26.04. I am new to all this. I have tried two different tablets, and both had the same issue. When I tried it shows the pointer moving, but I can't click on icons or draw. This is for both Krita and Open Toonz. I hadedownloaded the driver for my Huion Kamvas pro 16. (I also tried my Wacom Intuos pro too). I searched and people blamed a new xwayland update, a few people said it broke it, they rolled back the update. I only have the newest edition. Is there something I can do? Or just wait until they do a new update to resolve the issue?

When I test the tablet and pen in the test area on Ubuntu desktop tablet area properties, it works, the pressure sensitive also works.

Install ROCm 7.2 instead of 7.1 on Ubuntu 26.04 LTS – or update coming? https://askubuntu.com/questions/1566539/install-rocm-7-2-instead-of-7-1-on-ubuntu-26-04-lts-or-update-coming

I've been eagerly waiting for Ubuntu 26.04 LTS because I knew ROCm would be installed automatically with it. Now I'm disappointed to see it's only ROCm 7.1.0 / 7.1.1 which does not work well with newer AMD Strix Halo designs like AMD RYZEN AI MAX+ 395 with Radeon 8060S (gfx1151).

To get the full potential of this GPU and NPU, I have to use ROCm 7.2 and later. First question is:

  • Should I install ROCm 7.2 myself despite there is not even an installation guide for Ubuntu 26.04 in the official documentation yet, or
  • eagerly wait for a ROCm update to come to Ubuntu 26.04 via system updates?

I would happily wait 1 or 2 months, but if this update is not to be expected in the near future then I most likely would have to do it myself. How to start?

Problem z Ubuntu 26.04 LTS https://askubuntu.com/questions/1566352/problem-z-ubuntu-26-04-lts

I'm having a problem with Ubuntu 26.04 LTS. After updating from 25.10 to 26.04 beta at first then to the 26.04 LTS and it started freezing, meaning it runs for about 10 seconds and then freezes for about 0.5 seconds. I watch YouTube and it freezes regularly. I do a speed test on the website, and it freezes for 0.5 sec after around 5-10 sec. I play on Steam and it freezes, but I can hear that the graphics card isn't working at the moment—it doesn't make the same noises it normally does. When watching YouTube or running speed tests on the website, the CPU temperature is a maximum of 70 degrees Celsius, and the GPU is 30 degrees Celsius. Everything works fine except for the freezing. My question is, how can I approach this? How can I diagnose the problem? Or what could be the cause?

Command result:

lspci -k | grep -A 3 -E 'VGA|3D|Display'
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 48 [Radeon RX 9070/9070 XT/9070 GRE] (rev c0)
    Subsystem: XFX Limited Device 8811
    Kernel driver in use: amdgpu
    Kernel modules: amdgpu

Update:

After reinstalling Ubuntu 26.04 LTS (clean install), the stutters still occur, i.e. the GPU and VRAM clock speeds drop to zero.

Best regards

Ubuntu 26.04 on Surface 7 pro https://askubuntu.com/questions/1565995/ubuntu-26-04-on-surface-7-pro

I have installed the newest Ubuntu 26.04 LTF. I have activated my PRO version. And I have followed the Surface 7 Pro instructions on Zorins forum (They were the newest I could find, and have worked for me on other Ubuntu based instalations until now.)

You can see the setup here: https://help.zorin.com/docs/getting-started/set-up-microsoft-surface-device/

But when I follow those instuctions, and reboot my computer, I just get a text based login screen. And I can't get to the Ubuntu GUI from there.

What do I do wrong.

Would it be possible, that the Ubuntu install, checks for a Surface computer, and automatically sets up the kernal on install?

I'm looking for help to get my Arvox AX900 USB wifi + BT 5.4 adapter to work on a fresh install of Ubuntu Server 25.10 (Kernel 6.17). I could not find vendor specific drivers, but I did find out that this specific hardware i.e. AIC 8800D80 has generic drivers that should work. In my case, I have tried downloading the drivers from Tenda's website as well as a git. Initially, they did not install because the OS was missing some basic packages primarily because I did not have a wired internet connection to my workstation. So, I downloaded the required packages on a different laptop and then copied them over and installed them. Post this, the driver did get installed successfully but even after a reboot, Ubuntu does not show an available Wifi adapter. I followed a blog to download the source files (which I did from the git), compile them on my Ubuntu and then installed them. However, the end result was the same. The Network Manager does not show any new Wifi adapter. Here are additional steps I have taken to check configurations:

  • lsusb - shows the adapter as soon as I connect it
  • dmesg - shows that the firmware was loaded on boot
  • sudo iw list - does not give any output

I have also referred to various posts on serverfault, askubuntu, stackoverflow etc. to identify what I may be doing incorrectly and as per their comments, the adapter should work after following those steps. However, it hasn't helped in my case. Hence, I'm posting here for help. I'm new to the Linux world and am trying to learn to find my way around it. It will be very helpful if someone can guide me here as I want to avoid purchasing another wifi dongle (available ones are quite expensive).

Enable RDP from command line https://askubuntu.com/questions/1499789/enable-rdp-from-command-line

I'm working remotely via SSH connection and need to use some GUI applications on the remote machine. I do not have an X-Server for X forwarding on my local machine, but a RDP client.

Can I somehow enable RDP via command line?

Usually one would do this in the Settings app in the "Sharing" tab.

Remmina rdp from linux to windows: win key and others not working inside session https://askubuntu.com/questions/1481482/remmina-rdp-from-linux-to-windows-win-key-and-others-not-working-inside-session

I'm connected with remmina from ubuntu to windows 10 in full screen mode. If I press WIN it does not display the windows start menu, but the ubuntu activities instead. It's like, if those keys were not mapped at all in remmina, they keep working as if I was only using linux.

Can I get a fully immersive session, where no matter what key I press, it's handled by windows and not linux?

Cannot connect to Ubuntu 22.04 through RDP https://askubuntu.com/questions/1478769/cannot-connect-to-ubuntu-22-04-through-rdp

PROBLEM: can't connect to my Ubuntu server through RDP.

MSTSC RETURNS:

[Window Title] Remote Desktop Connection

[Content] Remote Desktop can't connect to the remote computer for one of these reasons:

  1. Remote access to the server is not enabled
  2. The remote computer is turned off
  3. The remote computer is not available on the network

Make sure the remote computer is turned on and connected to the network, and that remote access is enabled.

[Expanded Information] Error code: 0x204 Extended error code: 0x0

XRDP INSTALLATION PROCESS I USED:

  1. sudo apt-get update
  2. sudo apt install xfce4 xfce4-goodies xrdp net-tools xorg dbus-x11 x11-xserver-utils #I followed different installation guides in case the problem was caused by lacking some packages + I installed net-tools to check stuff with netstat
  3. sudo systemctl status #checked that xrdp was running
  4. sudo adduser xrdp ssl-cert
  5. sudo systemctl restart xrdp
  6. sudo ufw allow from any to any port 3389
  7. sudo ufw allow 3389

SOLUTIONS I TRIED:

  1. made sure that xrdp was listening to 3389 using netstat
  2. made sure that 3389 port was opened
  3. made sure that the VM port was opened in the VM hosting service I use
  4. made sure that the xrdp.ini file didn't have incorrect setting inside
  5. made sure use_vsocket was set to =false
  6. made sure that automatic login was turned off
  7. tried logging out and connecting through mstsc, got the same result
  8. tried rebooting :)
  9. went through xrdp logs with journalctl xrdp - seems like there was no connection

INFORMATION THAT MIGHT BE VALUABLE:

  1. for connection I'm trying to use the default user "ubuntu" with sudo privileges which was created during VM set up
  2. I'm new
Mount Network Drive Permanently in Ubuntu 22.04.1 LTS https://askubuntu.com/questions/1429900/mount-network-drive-permanently-in-ubuntu-22-04-1-lts

I want to mount a LAN Network Drive that I can access from Files/Nautilus as soon as I login to my Ubuntu desktop.

I can do this manually with the following command:

sudo mount -t cifs -o user=user,password=***,vers=1.0  //192.168.XX.XX/sda1 /media/sda1/

If I reboot the system, I loose the file location of my drive and find myself running the command again. Another manual method that works is by :

Cntrl+L and then typing smb://192.168.XX.XX/sda1/

Can you recommend me a tutorial that will allow me to accomplish my goal or let me know the steps to mount this Network drive that is attache to my router BTW.

How can I mount/recover my ecryptfs-encrypted home? https://askubuntu.com/questions/1164016/how-can-i-mount-recover-my-ecryptfs-encrypted-home

I recently found an old disk with files in my ecryptfs-encrypted home folder that I want to recover. However I cannot boot into the system as it does not boots not. I need to attach the old disk to my new computer and recover the files from the CLI.

How can I get access to my old files?

How do I install drivers and configure my screen to work? (15.04, nvidia 760 gtx, QNIX QX2710) https://askubuntu.com/questions/623274/how-do-i-install-drivers-and-configure-my-screen-to-work-15-04-nvidia-760-gtx

Every time I try to install the Nvidia drivers for my graphics card, the GTX 760, I end up with a black screen on boot which stops me from using the computer.

This happens regardless of where I download it from, it seems, as I've tried both with the Nvidia website, apt-get and Ubuntu Software Center. I've tried nvidia-current (349) as well as 319, with the same result from both.

I actually sat down and read Nvidia's readme as well, which simply doesn't help.

How do I install drivers that work? Could I be missing a step?

EDIT: Apparently it's not my graphics drivers that are messing with my - it's my screen. I have one of those cheap 27" 2560x1440 monitors, a QNIX QX2710, and this monitor does not report it's EDID correctly. I tried following a couple of guides but with no progress. I'll put this on hold, it's simply not worth the time and frustration.

I have Dolby Virtual Surround Sound 5.1 speakers with Tuba CineBass Subwoofer on Acer laptop (mine is 5951G but there is also bunch of models with similar configuration of speakers with/without subwoofer). In Windows it works and sounds amazingly after installing both Realtek drivers and Dolby software from Acer support site. In Ubuntu only 2-channel sound is working.
