Same problem here, using Kubuntu 24.04 on a fresh install (with Xorg). Intermittent flickering of the whole screen; I could not determine a specific pattern that caused it. Happened several times per day, usually briefly but sometimes for several seconds.
Adding "i915.enable_dc=0 intel_idle.max_cstate=2" to the grub defaults fixes the issue completely; no further flickering observed in about a week of usage. System: Thinkpad T470 lspci -s 00:02.0 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02) Let me know if any information or testing I could provide would help fix this for others. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2062951 Title: Random flickering with Intel i915 on Linux 6.8 (Ubuntu 24.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2062951/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
