[Bug 2137213] Re: Ryzen 5 5600U graphics driver broken in kernel 5.15.0-164

Glad to hear that! I can close this bug as Fix Released, the only reason
we might reopen is if we see the same issue on another kernel version,
there's no additional work we could do if we found out where exactly the
bug came from at this point.

** Changed in: linux (Ubuntu)
Status: Confirmed => Fix Released

Title:
Ryzen 5 5600U graphics driver broken in kernel 5.15.0-164

Status in linux package in Ubuntu:
Fix Released

Bug description:
When I updated Xubuntu 22.04.05 LTS from kernel 5.15.0-153 to
5.15.0-164, the screen would stay black after boot. Setting nomodeset
at boot time seemingly fixed the issue except that Xubuntu showed the
default desktop background instead of the one I set in preferences.
Later, it also turned out that when trying to play SuperTuxKart, it
would stop updating its screen just when a race was supposed to start.

Reverting to kernel 5.15.0-153 fixed the issue and using a live CD of
Xubuntu 24.04 with a 6.8-series kernel also worked without a hitch.

As per inxi, the CPU is:
CPU: 6-core AMD Ryzen 5 5600U with Radeon Graphics (-MT MCP-)
