Description Fxzx micah 2025-02-18 10:41:45 UTC
1. Please describe the problem:

This issue occurs when I use wayvnc in nspawn.
"wayvnc -g -r -f 60"

2. What is the Version-Release number of the kernel:

kernel-6.12.13-200.fc41.x86_64

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

The last kernel version that did not have this problem was kernel-6.12.11-200.fc41.x86_64.
Sorry I skipped kernel-6.12.12-200.fc41.x86_64 so I don't know if it works on kernel-6.12.12-200.fc41.x86_64.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

*Run wayvnc in an nspawn container with hyprland installed.*

Sorry, I don't know if wayvnc will come back to normal if I don't run it inside a container, because my host system's DE is Gnome and wayvnc doesn't support Gnome.

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

I don't know, please let me know if it is necessary for me to perform this step.

6. Are you running any modules that not shipped with directly Fedora's kernel?:

No

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

Please let me know if this step is also necessary, as I actually checked the kernel logs and found no exception related to the problem.

Reproducible: Always

Comment 1 Fxzx micah 2025-02-20 14:05:25 UTC
Sorry, but I dug deeper into the issue and found that if I install the nvidia proprietary driver, the error reported becomes as follows:

[drm:nv_kthread_q_stop [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Cannot create sg_table for NvKmsKapiMemory 0x00000000206e8d05

And this error is no longer output by wayvnc but appears in the kernel error log.

That is, this is not a single kernel bug but is related to both the kernel and the nvidia kernel module.

Yes, I'm using a common dual graphics laptop.

I'm currently experiencing this issue on my web game project hosted at https://slopeonlinegame.github.io. The game relies on GPU acceleration via WebGL, and ever since this bug started occurring, the game fails to launch properly on affected Fedora systems.

Comment 3 Adam Williamson 2025-12-02 02:24:10 UTC
This message is a reminder that Fedora Linux 41 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 41 on 2025-12-15.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '41'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 41 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 4 Samyak Jain (RedHat) 2025-12-16 18:45:51 UTC
Fedora Linux 41 entered end-of-life (EOL) status on 2025-12-15.

Fedora Linux 41 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

Thank you for reporting this bug and we are sorry it could not be fixed.
