https://bugzilla.kernel.org/show_bug.cgi?id=201139 --- Comment #6 from Aleksandr Mezin (mezin.alexander@xxxxxxxxx) --- On both monitors there are no "Auto" input option. DisplayPort is selected on both of them. Also, I've never seen similar problem on RX 580 with the same monitors, either on Linux or Windows. On Windows I frequently see notifications about "link failure" or something like that, but on Windows the driver/card always recovers successfully (so no other problems except the annoying notification). Also, more details, maybe it wasn't clear: 1. After dpms suspend, both monitors woke up, but one of them was showing black screen (but no "no signal" osd or anything like that). No mouse pointer too. But I was able to move the cursor away from the working monitor. xrandr and Gnome settings were showing both monitors too. 2. I turned that "non-working" monitor off. Now the previously working monitor only shows the black screen too. 3. I turned on the second monitor. Black screen moved to it, first monitor started working completely fine. 4. I thought that it's maybe a bug in compositor, so I tried switching VTs, logging out, restarting GDM. It didn't help. 5. Logged in back to Gnome. By changing settings/turning displays on and off I somehow managed to "move" the black screen to the first monitor, and the second one started working. But exactly one monitor (either first or second one) was always showing the black screen. 6. Rebooted, both monitors started working fine -- 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
