[Bug 2069163] Re: Black screen flickering on resume [22.04] [i915]

** Description changed:

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 (i.e. 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.

- Running `ubuntu-bug linux` gives me a PermissionError(13, 'Permission
