https://bugzilla.kernel.org/show_bug.cgi?id=206021 Bug ID: 206021 Summary: AMDGPU/DC: freesync disabled on the monitor side after the monitor sleeps and resumes Product: Drivers Version: 2.5 Kernel Version: 5.4 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: libcg@xxxxxxxxxxxxxx Regression: No Created attachment 286525 --> https://bugzilla.kernel.org/attachment.cgi?id=286525&action=edit Freesync ON linux 5.4.6 xorg-server 1.20.6 xf86-video-amdgpu 19.1.0 mesa 19.3.1 gnome-shell 3.34.2 R9 Fury Samsung C27HG70 with 1023.0 firmware Steps to reproduce: - Hit Super+L to lock screen - Wait for the monitor to turn off (blinking status LED) - Wake up screen by hitting any key Before going to sleep, the monitor will show that Freesync is active in the OSD (see freesync_on.jpg attachment). After sleep, Freesync will be disabled in the OSD (see freesync_off.jpg). However the driver still thinks Freesync is active: in games, the screen will turn blank when the framerate goes below 144Hz. It's possible to recover by replugging the displayport cable or by manually powering the monitor off and back on. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
