[Bug 1958191] Re: [i915] Screen flickering in Ubuntu 22.04 (until i915.enable_dc=0 intel_idle.max_cstate=2 are added)
Following up on this: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191/comments/16 Booting with 5.15.0-25-generic and the i915.enable_dc=0 intel_idle.max_cstate=2 configs seems to fix the issue on my hardware. 5.15.0-27-generic won't stop shaking randomly no matter what value I test on intel_idle.max_cstate. It seems to get worse when there are many windows on the screen or something is zoomed in/out. For example, on shopping sites like aliexpress, hovering with the mouse on the product normally spawns this window with the zoomed product, I noticed that this caused a lot of shaking. Reading stuff, especially with images seems to cause it more regularly as well. However, watching videos was fine all the time. I can also confirm that the kernel 5.13.0-20-generic works without an issue with the same hardware as some of my work colleagues have the same machine running Ubuntu 21.10 with that kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm not using wayland. I stated that I was on X11. I did sudo update-grub indeed! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm having the same issue, I'd like to add that I've tested both Xubuntu 22.04 and Ubuntu 22.04 and was able to reproduce the same error. Now I'm running Kubuntu 22.04 with the following spec: OS: Kubuntu 22.04 LTS x86_64 Kernel: 5.15.0-27-generic Shell: bash 5.1.16 Resolution: 1920x1080 @ 120Hz DE: KDE Plasma 5.24.5 KDE Frameworks Version: 5.93.0 WN: Kwin 5.24.5 Qt Version: 5.15.3 Graphics Platform: X11 Host: GL62 6QF REV:1.0 CPU: Intel i5-6300HQ (4) @ 3.200GHz GPU: Mesa Intel® HD Graphics 530 GPU: NVIDIA GeForce GTX 960M Here's another video of the issue: https://streamable.com/b9792p PS: I added GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_dc=0 intel_idle.max_cstate=2" to /etc/default/grub and I still have some instances of screen shaking. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
