Public bug reported: The Tongfang PH4TUX1 barebone has occasional display flickering with a 3k eDP display on 5.11 ubuntu kernel, but not on 5.8 ubuntu kernel.
Setting i915.enable_psr=0 as a boot parameter fixes the issue, so my guess is that this patch missing on 5.11 is causing the regression: https://kernel.ubuntu.com/git/ubuntu/ubuntu- focal.git/commit/?h=hwe-5.8&id=c6625a005bd1a2e02773c7633df211be95fa0d09 Will this default disabled-behaviour be carried over to 5.11? ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1938039 Title: Tongfang PH4TUX1 flickering with 3k eDP Display on 5.11 Status in linux package in Ubuntu: New Bug description: The Tongfang PH4TUX1 barebone has occasional display flickering with a 3k eDP display on 5.11 ubuntu kernel, but not on 5.8 ubuntu kernel.
