My second monitor has suddenly stopped working after a reboot.
I'm on Ubuntu 18.04 with an OpenBox desktop and an nVidia 1060, using the nVidia 396 driver. I've been fiddling with my display settings a bit because of a different problem and after a reboot, the second monitor says "no signal", and my double-wide desktop has shrunk to a single monitor. I have no idea what I've done!
xrandr reports only one monitor (HDMI-0) despite HDMI-1 also being plugged in:
$ xrandr Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 DVI-D-0 disconnected primary (normal left inverted right x axis y axis) HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 59.93*+ 60.00 59.94 50.00 60.05 60.00 50.04 1680x1050 59.95 1600x1200 60.00 1440x900 59.89 1440x576 50.00 1400x1050 59.98 1280x1024 75.02 60.02 1280x960 60.00 1280x720 59.94 50.00 1152x864 75.00 1024x768 75.03 70.07 60.00 800x600 75.00 72.19 60.32 56.25 720x576 50.00 720x480 59.94 640x480 75.00 72.81 59.94 59.93 HDMI-1 disconnected (normal left inverted right x axis y axis) 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 disconnected (normal left inverted right x axis y axis) Things I've tried:
lxrandr, arandr, and nvidia-settings all fail to detect it.
I was told xrandr --output HDMI-1 --auto might reactivate it, but it didn't.
Unplugging and replugging the cables made no difference.
Any help appeciated!
Reset to default
