[Kernel-packages] [Bug 1970426] Re: [i915] screen suddenly starts flickering after update

[Johannes Stöckelmaier]

I did the following changes and am now flicker-free for two days:

In file /etc/default/grub I added to parameter GRUB_CMDLINE_LINUX_DEFAULT:
i915.enable_dc=0
intel_idle.max_cstate=2

then:
sudo update-grub
reboot

My laptop is now usable but it cant be a permanent solution to disable
energy saving features on a low-energy laptop. I will report in a week
if this indeed fixes the flickering or if it just happens less often.
