I cannot get my second monitor to turn on, which uses Displaylink “Pluggable USB 2.0 Display Adapter”.
I have gone through the steps here: wiki.archlinux. org / index.php / DisplayLink (it won’t let me include a proper link??!?)
$ xrandr --setprovideroutputsource 1 0
$ xrandr --listproviders
Providers: number : 2 Provider 0: id: 0x63 cap: 0x7, Source Output, Sink Output, Source Offload crtcs: 2 outputs: 2 associated providers: 1 name:nouveau Provider 1: id: 0xa8 cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
Great, 2 providers are shown.
$xrandr --output DVI-I-1-2 --auto --output DVI-I-1-2
returns this error:
xrandr: Configure crtc 2 failed
If I use GUI Display Configuration, I can see the second monitor, but it will not activate.
One odd thing I just noticed, the screenshot tool sees an extra screen to the right (when doing “Full Screen” screenshot, it shows a black area to the right).
Finally, the second monitor does light up when I’m shutting down. It does not render any clear image, rather it is just a bunch of purple lines and stuff. But shutdown process is the only time it lights up.
I found this in
