Public bug reported:
Affected machine: Lenovo ThinkPad X13 Yoga Gen 2
OS: Ubuntu 22.04.2 LTS (64-bit)
I did a dist-upgrade on Feb. 16th, and every boot after that results in
screen flickering, I checked the dpkg history and assume that the kernel
upgrade(5.19.0.32.33~22.04.9) is the one to blame. Then I tried to boot
the machine with the former kernel(5.15.0.25.27), everything works fine
again which confirms my assumption.
The following line repeated to show up before entering the desktop:
