Title:
Black screen flickering on resume [22.04] [i915]
Status in linux package in Ubuntu:
Confirmed
Bug description:
When waking the system from suspension, the screen turns black and
flickers repeatedly for a minute, until it gets back to normal.
This issue is closely related to this other bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191
Indeed, the black-screen flickering affected also booting, but adding
the kernel parameters suggested in the link (`i915.enable_dc=0
intel_idle.max_cstate=2`) solved that at least for boot.
I'm on Linux Mint 21.3 (Ubuntu 22.04) with 6.5 kernel. I tried other
kernels (5.4, 5.15) and drivers (545, 470, 390, Nouveau), but nothing
changed. This issue didn't happen on Focal 20.04.
