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
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.
