Update: Here is my video adapter info... ``` $ lspci | grep NVIDIA 0a:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] (rev a1) 0a:00.1 Audio device: NVIDIA Corporation GP106 High Definition Audio Controller (rev a1) ```
It's interesting that I also have the problem with mu audio inputs / outputs switching around and my audio controller is also NVIDIA. Probably just a coincidence? ----- This has been a problem with multiple monitors in Linux since forever. I have a shell script that I run which will fix things about 80% of the time. The rest of the time I have to reboot. If I could simply disable the system's display auto-detect and force a configuration, that'd go a long way toward fixing this permanently. It happens about 90% of the time when waking up from sleep. About ten percent of the time the computer will wake up with everything in the right place and that is always a delightful surprise. FYI, the audio outputs switch around too. My microphone input and audio outputs will switch around sometime between when the PC sleeps and wakes back up. I'd also like to be able to fix that too, but right now am only focused on the monitors. I have a desktop with three monitors. One 55" Samsung 4k and two 1920x1080 Sceptre curved, widescreen displays. The two Sceptres are stacked and to the left of the 55" Samsung. When the computer wakes from sleep, the monitors will have been reconfigured from "Join" to "Mirror". When I reconfigure them to "Join" then the displays will have been reconfigured with the Display Port (DP-3) monitor no longer being listed and one of the Samsung monitors showing a 4k resolution and the other one showing the proper resolution. When I run this shell script (xrandr command), the DP-3 monitor will re- appear, but I will have to use the displays ui to drag them back into the proper orientation. ``` xrandr \ --fb 5760x2160 \ --output HDMI-1 --mode 1920x1080 --pos 0x0 --rotate normal \ --output HDMI-0 --mode 1920x1080 --below HDMI-1 --rotate normal \ --output DP-3 --mode 3840x2160 --right-of HDMI-1 --scale 1x1 --rotate normal; ``` Here is my current (correctly configured) `xrandr -q`... ``` Screen 0: minimum 8 x 8, current 5760 x 2160, maximum 32767 x 32767 DVI-D-0 disconnected (normal left inverted right x axis y axis) HDMI-0 connected 1920x1080+0+1080 (normal left inverted right x axis y axis) 480mm x 260mm 1920x1080 60.00*+ 59.94 50.00 60.05 60.00 50.04 1600x900 60.00 1280x1024 60.02 1280x960 60.00 1280x800 59.81 1280x720 60.00 60.00 59.94 50.00 50.00 1152x864 60.00 1024x768 60.00 800x600 60.32 56.25 720x576 50.00 720x480 59.94 640x480 75.00 72.81 59.94 59.93 HDMI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 480mm x 260mm 1920x1080 60.00*+ 59.94 50.00 60.05 60.00 50.04 1600x900 60.00 1280x1024 60.02 1280x960 60.00 1280x800 59.81 1280x720 60.00 60.00 59.94 50.00 50.00 1152x864 60.00 1024x768 60.00 800x600 60.32 56.25 720x576 50.00 720x480 59.94 640x480 75.00 72.81 59.94 59.93 DP-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DP-3 connected primary 3840x2160+1920+0 (normal left inverted right x axis y axis) 1872mm x 1053mm 3840x2160 30.00*+ 59.94 50.00 29.97 25.00 23.98 4096x2160 59.94 50.00 29.97 25.00 24.00 23.98 1920x1080 60.00 59.94 50.00 29.97 25.00 23.98 60.00 50.04 1680x1050 59.95 1600x900 60.00 1440x900 59.89 1366x768 59.79 1280x1024 75.02 60.02 1280x800 59.81 1280x720 60.00 59.94 50.00 1152x864 75.00 1024x768 75.03 70.07 60.00 800x600 75.00 72.19 60.32 720x576 50.00 720x480 59.94 640x480 75.00 72.81 59.94 ``` -- 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/1927948 Title: Windows switch monitor after resuming from sleep Status in GNOME Shell: New Status in Mutter: New Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: What I expect: Window layout/positioning is identical after resume from sleep.
