Screen goes blank

[ubuntu user]

Screen goes blank after the desktop environment gets loaded. I use the cinnamon desktop. After I type in the user password at the display-manager to login, the desktop shows for 1 second and then the screen goes blank. I solved the problem through switching the desktop to cinnamon (software rendering) at the display-manager and then installed 6.2.0-34-generic instead of 5.15.0-86 to be able to use the normal cinnamon desktop again.

Am experiencing a similar issue which may be the same bug.

OS: Ubuntu 20.04
Kernel: 5.15.0-86-generic
Desktop: GNOME
Graphics: AMD

Just before/after logging in, the screen flickers and/or goes blank. Attempting to switch to a terminal using Ctrl+Alt+F-keys doesn't help. Attempting to restart using Ctrl+Alt+Del doesn't work.

Choosing the previous kernel (5.15.0-84-generic) from the GRUB menu instead, when booting, avoids the issue.

Sorry for being late I just ran the command and sent the report. forgot to mention that I had problem with the keyboard too after the login. in order to send the report I went back to the kernel with the bug 5.15.0-86-generic (hopefully send valuable report) and choose cinnamon software rendering.

I have similar problems with a lenovo m625q with Stoney graphics:
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Stoney [Radeon R2/R3/R4/R5 Graphics] (rev d4)
Since 5.15.0-86 (Ubuntu 20.04 HWE):
After entering the password in the dm and mate startup, the machine crashes.
A twin system without graphic login works with out issues.

...are reporting that kernel 6.2 solves the problem for them. I haven't tested this for myself yet.
