[Bug 1970426] Re: [i915] screen suddenly starts flickering after update
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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970426 Title: [i915] screen suddenly starts flickering after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1970426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1368402]
Xubuntu 20.04 Managed to fix it. ``` sudo apt remove xserver-xorg-input-synaptics reboot ``` The package `xserver-xorg-input-synaptics` is not included in Ubuntu 20.04 . Not sure why it is included in Xubuntu 20.04 release. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1368402 Title: GTK3 apps don't understand natural scrolling in Xubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/xfce4-settings/+bug/1368402/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
