As for me there are 2 ways to get rid of flickering, but both are not make me happy: Either in grub add: - GRUB_CMDLINE_LINUX="intel_idle.max_cstate=4" or (that is new to me) - change screen resolution(!?!) Anything else than 1920x1080 works! If I can add custom resolutions I would play with that. But only 1600x900 matches my ration.
Maybe this 2nd workaround gives the developers a clue what is the original issue here. Hope to get some feedback. Maybe this is the reason there are not to many that complains about that issue, although nowaday this resolution is standard. Beside that I have testet a lot of other things, kernel options as GRUB_CMDLINE_LINUX="i915.enable_psr=0" or in i915.conf options i915 enable_guc=2 options i915 fastboot=1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872760 Title: i915 - after return from suspend display is flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
