I cannot boot after update Kernel 6.17.11.300

Ask Fedora

I use Fedora in my Gaming PC wich is in exclusive configuration :

  • Virtual diplay with custom Edid in grub.cfg (GRUB_CMDLINE_LINUX video drm.edid_firmware)
  • Sushine for moonlight
  • module Xone (for xbox gamepad) signed for secure boot

Since yesterday, i cannot boot on Fedora.

Can you help me with any step i have to repaire my installation.

The PC steel working great with the last Kernel 8.17.10.300 ! (but is anoying because i have to connect à display to use grub and chose the none default kernel)

In journalctl i found this error “Could not load the Qt platform plugin “xcb” in “” even though it was found.” and it repeat and repeat and never boot.

My mistakes :

  • I used a custom Edid in /usr/lib/firmware/edid/ but i forgot to add it to initramfs with dracut ! But it was not probleme with the last kernel, and until i saw this error i add configuration in /etc/dractu/custom/custom.cfg and apply dracut --regenerate-all --force
    is steel working with last kernel
  • i tried multiple copr to finaly make Xone work (Making sure you're not a bot! and this one Making sure you're not a bot!) but in the end it was working and steel work with last kernel to

After some test, i found the root cause.
The Kernel Option in GRUB_CMDLINE_LINUX=“video=DP-1:2560x1440@144e” its making the failure in kernel boot

You can use grubby tool to set :

List all installed kernels
--------------------------

To get the index number of all the installed kernels:

  sudo grubby --info=ALL | grep -E "^kernel|^index"

The output should be something like this:

index=0
kernel="/boot/vmlinuz-6.11.11-200.fc40.x86_64"
index=1
kernel="/boot/vmlinuz-6.11.10-200.fc40.x86_64"
index=2
kernel="/boot/vmlinuz-6.11.8-200.fc40.x86_64"
index=3
kernel="/boot/vmlinuz-0-rescue-6a0d0e8a953c43e682bd4f1a6e0143be"

Change the default kernel using index
-------------------------------------

Now we can change the default kernel by using the index number:

 sudo grubby --set-default-index=1

Verify the default kernel
-------------------------

Verify that the right kernel has been set as default:

   sudo grubby --default-title

The output will be the default kernel title:

Fedora Linux (6.11.10-200.fc40.x86_64) 40 (Workstation Edition)

Do not forget, if you install a newer kernel the index get set to 0 again and you would habe to repeat the steps above, if your system still is not boot able as you like.

Thank you, for now, i will use the 6.17.10.xxx kernel to boot.
But i continue my search to understand what is happening. It seems to be related to AMDGPU drivers.
