@Davron - downgrading the kernel to 6.7 should work for now, but I just went back to 22.04 as I also had issues with laptop shutdown state etc Also worth clicking the "this bug affects me" thing at the top as I don't think devs will bother unless the issue gets some visibility. Seen quite a few others on Reddit with same or similar issues so it definitely affects more than is showing here. -- 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 i915 on Linux 6.8 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
[Bug 2062951] Re: Random flickering with i915 on Linux 6.8
This has happened since the very first day of a clean installation on a pc. Thought since it might not have downloaded all drivers yet, maybe it would get fixed over time, but it still persists.

This seems to be related to the newer Intel Xe driver included with kernel 6.8.x as it only occurs when the driver is enabled. When using nomodeset in grub, there are no issues (besides losing brightness controls etc from no driver being loaded). -- 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 i915 on Linux 6.8 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

I've tried adding "intel_idle.max_cstate=4" too but it didn't fix anything for me. Both KDE Plasma and Xfce have the same behavior. I'm also on a Skylake GT2 [HD Graphics 520] - no issues on 23.10 as I didn't change kernel, but 24.04 with kernel 6.8 is where I'm experiencing this. -- 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 i915 on Linux 6.8 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

[Bug 2062951] Re: Random flickering with i915 on Linux 6.8
Update: I did some preliminary testing and it seems like adding "intel_idle.max_cstate=4" to cmdline resolves the issue but probably at the power efficiency cost. I also tried "i915.enable_psr=0" but it didn't help just made the flickering a slightly different. -- 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 i915 on Linux 6.8 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
