Fedora 31
When installing, I had a Dell monitor attached to an nvidia graphics card via HDMI and that was working fine. I
installed the nvidia drivers for this.
I now want to use an old ViewSonic monitor as a second monitor so I plugged it into the on-board VGA port and booted.
The ViewSonic monitor is now the only monitor working. I adjusted the settings to make the display useable (Settings ->
Devices -> Displays) but only the ViewSonic monitor is listed here.
Google has led me to try this:
simon@hedgehog ~]$ lspci | grep -i VGA
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Desktop 9 Series) (rev 02)
01:00.0 VGA compatible controller: NVIDIA Corporation GP108 [GeForce GT 1030] (rev a1)
[simon@hedgehog ~]$ xrandr -q
Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 16384 x 16384
HDMI-1 disconnected (normal left inverted right x axis y axis)
DP-1 connected primary 1600x1200+0+0 (normal left inverted right x axis y axis) 432mm x 324mm
1600x1200 60.00*+

1280x1024 75.02 60.02
1280x960 60.00
1152x864 75.00
1024x768 75.03 70.07 60.00
832x624 74.55
800x600 72.19 75.00 60.32 56.25
640x480 75.00 72.81 66.67 59.94
720x400 70.08
** Note that there is an HDMI connector on the motherboard as well so I am not sure if HDMI-1 here refers to that.
I tried this:
[simon@hedgehog ~]$ xrandr --output HDMI-1 --auto --right-of DP-1
[simon@hedgehog ~]$
... but there was no output and nothing changed.
I would like to end up with a separate desktop on each monitor.
Any help gratefully received.
Simon
