The 'quiet' workaround of the other bug does not help for my machine.

[Bug 1958248] [NEW] Screen garbled on login and freezes on unsuspend

2022-01-18 Thread Vic J
Public bug reported:

1. The login manager works but as soon as I log in, the screen is filled
with colored vertical stripes and is unusable.  I found that if I change
the screen resolution to the maximum (1920x1080), then the screen is ok.
Any other resolution that I've tried (eg (1440x900 used to be my
preference) causes the unreadable display and it does not revert back,
requiring a reboot.

2. Coming out of suspend, the password entry screen is displayed, but
there is no response to keyboard or mouse, requiring a reboot.

HP Envy x360 laptop with AMD Ryzen 7 with Radeon graphics

Last known kernel that worked is 5.11.0-46
