Hi! I'm using a Surface Laptop 3 (Intel version, i7-1065G7) which is running the i915 driver. I have a screen flicker issue in 5.5rc that I wasn't able to track down initially because of the sheer volume of commits to bisect. Luckily, I can reproduce the same issue on 5.4.6 now as well after the latest round of Arch Linux specific patches (upgrading arch1 -> arch3 will produce the bug). https://git.archlinux.org/linux.git/log/?h=v5.4.6-arch3 - During boot, the screen will flash to black for a second, then back on, two or three times. - After that, when starting a wayland session the same thing happens (also twice). - If I plug in a power cable, the same thing happens (again twice). It doesn't happen on unplug though. After the initial flicker, it's completely fine unless I plug a power cable in. I managed to bisect the issue down to 2-3 patches Kai Vehmanen made regarding intel_audio: It works on commit "x86/intel: Disable HPET on Intel Ice Lake platforms". But it doesn't work on "drm/i915: extend audio CDCLK>=2*BCLK constraint to more platforms" So one of these three patches cause it: - https://patchwork.freedesktop.org/patch/331957/ - https://patchwork.freedesktop.org/patch/334110/ - https://patchwork.freedesktop.org/patch/334111/ (I think it's not 334110, because I initially tested a build with just that commit reverted). Let me know if you need any specific debug information to diagnose further. -- Blaž _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
