Affects Xubuntu 22.04 too on Lenovo Ideapad 330s (Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz)
After about 11 days of using 22.04 release, it lead to major loss of productivity due to the flickering. Got headaches. This should have been a release blocker. I was curious if it affected Debian Unstable on their latest kernel (Linux 5.17.0-1-amd64 #1 SMP PREEMPT Debian 5.17.3-1 (2022-04-18) x86_64 GNU/Linux) and installed it. No flickering on Debian. Seems like it is a Ubuntu only bug. --- Below is a list of attempts I tried to fix flicker that DID NOT work during the 11 days of using Xubuntu 22.04: * GRUB Param `i915.enable_psr=0` workaround https://wiki.archlinux.org/title/intel_graphics#Screen_flickering * `intel_idle.max_cstate=4` option to grub param https://gitlab.freedesktop.org/drm/intel/-/issues/5569 * Use latest kernel from ubuntu team (linux-oem-22.04) * Use different kernel with `mainline` app - https://github.com/bkw777/mainline ``` * 5.17.5 - Did not fix. * 5.16.20 - Did not fix. * 5.15.36 - Did not fix. ``` * remove package `xserver-xorg-video-intel` https://en.itsmeit.net/how-to-fix-google-chrome-screen-flickering-on-ubuntu.html ** Bug watch added: gitlab.freedesktop.org/drm/intel/-/issues #5569 https://gitlab.freedesktop.org/drm/intel/-/issues/5569 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1970426 Title: [i915] screen suddenly starts flickering after update Status in linux package in Ubuntu: Confirmed Bug description: After I updated to 22.04 sometimes (about 3 ~ 4 times a day) the screen starts glitching and flickering like in the attached video and it doesn't stop until I move the cursor.
