Flashing screen, from boot, with Linux 5.19.12 on ThinkBook 13s G2 ITL

strongestpenguin · 2022-10-02 10:46:19

Hello,

I've recently updated my kernel and found out that my computer was unusable upon reboot.

RIght from the boot, me screen would continuously display a black screen with a white horizontal line for a split second, then turn completely black again for a full second, and continue doing this indefinitely.

Switching from linux to linux-lts (5.15.17) fixed the problem.

BIOS self-test of the complete hardware returns no errors.

Reading journalctl doesn't show any error as well.

I suspect that this has something to do with the GPU driver?

Some specifications:

In case anyone run into the same problem, try using an older kernel, or switching to linux-lts.
