https://bugzilla.kernel.org/show_bug.cgi?id=192921 Bug ID: 192921 Summary: Low frame rates and unrecognized monitor after kernel upgrade Product: Drivers Version: 2.5 Kernel Version: 4.10.0 Hardware: x86-64 OS: Linux Tree: Fedora Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: stevengruspier@xxxxxxxxx Regression: No Before upgrading my kernel (4.8.16), there was always a problem where at boot the refresh rate was too high, so my screen would flicker. I could only set the refresh rate to 120Hz max without any flickering. This was due to a bug or feature that had yet to be added to the kernel (was fixed in the DAL patched unofficial kernel). After upgrading the kernel to 4.9.3 I noticed that on boot there was no flickering at 144Hz anymore, but when trying to play games and videos there are issues with low frame rates. I then went to the display menu to check settings and noticed that the monitor now says "unknown". I installed 4.10.0 rc 3 from the rawhide repo with the same results. Distro: Fedora 25 GPU: ASUS Strix AMD R9 380 4GB Monitor: MG278Q (2560 x 1440 @ 144Hz) -- 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
