@Oibaf (oibaf) - I experienced the same issue on Xubuntu 22.04 too. The very last available xubuntu 21.10 kernel was fine. I upgraded from fully updated 21.10 to 22.40 and then the problem started. Not sure what is the latest 21.10 available kernel. Perhaps 5.13.0.1022.23 ? Not sure how to do a full research on that. -- 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/1958191 Title: [i915] Screen flickering in Ubuntu 22.04 (until i915.enable_dc=0 intel_idle.max_cstate=2 are added) Status in linux package in Ubuntu: Triaged Bug description: Ubuntu 22.04 development branch on kernel 5.15.0-17-generic @ 18/1/2022 Booting into desktop gets heavy screen flickering and disforming (unusable) both booting on xorg and wayland on kernel 5.13 it did not occur so heavy (only little glitches once in a while see bug 1948778) adding the kernel paramater intel_idle.max_cstate=4 fixed this i had these same bugs on this machine before: https://bugs.launchpad.net/ubuntu/+source/linux-hwe/+bug/1838644 https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1948778 ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: linux-image-5.15.0-17-generic 5.15.0-17.17 ProcVersionSignature: Ubuntu 5.15.0-17.17-generic 5.15.12 Uname: Linux 5.15.0-17-generic x86_64 ApportVersion: 2.20.11-0ubuntu75 Architecture: amd64 AudioDevicesInUse: USERPID ACCESS COMMAND /dev/snd/controlC0: lotuspsychje 1201 F pipewire-media- lotuspsychje 1207 F pulseaudio /dev/snd/seq:lotuspsychje 1193 F pipewire CasperMD5CheckResult: unknown CurrentDesktop: ubuntu:GNOME Date: Tue Jan 18 04:22:00 2022 Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 8087:0025 Intel Corp.

Issues started after upgrade to 22.04 (kernel 5.15, last 5.13 kernel from 21.10 was fine). A similar bug to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191 but adding below line to grub options: "i915.enable_dc=0 intel_idle.max_cstate=2" and executing "sudo update-grub" doesn't help.
