[Desktop-packages] [Bug 1842009] Re: [Wayland] Screen blanks for a second whenever discrete GPU is powered up
Thank you for reporting this bug to Ubuntu. Ubuntu 19.10 (eoan) reached end-of-life on July 17, 2020. See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed. ** Changed in: gnome-shell (Ubuntu) Status: New => Won't Fix ** Changed in: mutter (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1842009 Title: [Wayland] Screen blanks for a second whenever discrete GPU is powered up Status in GNOME Shell: New Status in gnome-shell package in Ubuntu: Won't Fix Status in mutter package in Ubuntu: Won't Fix Bug description: On this Kaby Lake G laptop, GNOME Shell blanks the screen for a second each time the AMD GPU is powered up.

Re: [Desktop-packages] [Bug 1842009] Re: [Wayland] Screen blanks for a second whenever discrete GPU is powered up
It looks like modesetting, or at least a destructive probe of the attached displays. There's nothing KMS related in dmesg corresponding to the blanking, so I don't think it's an invalid FB (I'd expect i915 to spit something in dmesg in that case) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1842009 Title: [Wayland] Screen blanks for a second whenever discrete GPU is powered up Status in gnome-shell package in Ubuntu: New Status in mutter package in Ubuntu: New Bug description: On this Kaby Lake G laptop, GNOME Shell blanks the screen for a second each time the AMD GPU is powered up.

Can you tell if the "blanking" is either: * The output entering sleep mode; or * A black frame being accidentally flipped.
