Hi,
I wanted to report this bug in the liquorix kernel that I'm seeing on the current version 6.16.5-1-liquorix-amd64. I don't know if previous versions are affected (the latest release of the previous 6.15 series works correctly).
When it shows up, the desktop freezes. However, I can log in via SSH from another PC, so it's only the graphics section that's having problems.
Thanks,
Antonio

I also tested previous versions, with the following results:

- 6.15.4 behaves the same as 6.15.5, freeze after a while in the graphical environment

- 6.16.3 freeze a few seconds after starting the graphical environment, after logging in with sddm

- 6.16.2 freeze after about 30 minutes

- 6.15.9 seems to work correctly

From experience, it might take some time for this issue to be resolved, if anyone is interested. In the meantime, is there a way to keep the liquorix kernel up to date without having to recompile it every time and without encountering this bug?

Can you provide the output of inxi -b? Also, can you reproduce this on a different 6.16 kernel?
