https://bugzilla.kernel.org/show_bug.cgi?id=208893 Bug ID: 208893 Summary: Navi (RX 5700 XT) system appears to hang with more than one display connected Product: Drivers Version: 2.5 Kernel Version: 5.8.1, 5.7.15 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: gordon@xxxxxxxxxxxxxx Regression: No I am using Fedora 32, and have tried the latest fixes with 5.8.1 mainline, and stable Fedora 32. If i connect a single monitor to my system it works fine. However, when I connect a freesync monitor (144Hz and another 24 inch monitor, the system during boot shows much larger startup times, and also general hanging, the screen flickers too but ONLY when the second monitor is connected.) When I boot the system, even the 'booting' is delayed considerably by comparison when the second display port monitor is connected. It seems to be one of two problems: - with multiple displays the card is not behaving properly - the difference in refresh rates is causing a problem / conflict. I do not know for certain where the problem lies, but even booting is slowing down so I do not believe this is purely a Mesa issue. Using wayland or xorg seems to make little difference the problem is on both, and even on terminal sessions (slowing down terminal output to the display and general unresponsiveness) however as stated above, rebooting with a single display resolves these problems. -- 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
