Public bug reported: If I have a thunderbolt monitor, it works fine-ish, most of the time, and I can connect, disconnect, etc.
If EVER I connect to an HDMI monitor, it connects and will disconnect, but then displayport NEVER WORKS AGAIN until I reboot the laptop. After using and disconnecting HDMI: shevek@starling:~$ xrandr -q Screen 0: minimum 8 x 8, current 3840 x 2160, maximum 32767 x 32767 DP-0 connected (normal left inverted right x axis y axis) 2560x2880 60.00 + DP-1 connected (normal left inverted right x axis y axis) 4096x2304 60.00 + 3840x2160 60.00 3200x1800 60.00 2560x2880 60.00 2560x1440 60.00 640x480 59.94 HDMI-0 disconnected (normal left inverted right x axis y axis) eDP-1-1 connected 3840x2160+0+0 (normal left inverted right x axis y axis) 344mm x 193mm 3840x2160 60.00*+ 59.98 59.97 3200x1800 59.96 59.94 2880x1620 59.96 59.97 2560x1600 59.99 59.97 2560x1440 59.99 59.99 59.96 59.95 (etc) BUT: + xrandr --output DP-1 --mode 3840x2160 --above eDP-1-1 xrandr: Configure crtc 0 failed X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 21 (RRSetCrtcConfig) Value in failed request: 0x0 Serial number of failed request: 55 Current serial number in output stream: 55 and then the screen goes blank. And now I have to reboot again, which is kind of meh because of #1852797 the laptop crashes every day or two anyway on 19.10 where it didn't crash on 19.04 but ... still a pain. This bug existed on 19.04 with nvidia-driver-418 and exists in nvidia- driver-430.
