Just elaborating in case anyone needs easier steps for systemd like me as I didn't know xrandr really well. This post got me on the right track however. I'm happy the displaylink made the effort and released a driver for the D3x because I can't work with Windows efficiently. I tried for 2 months...
If the driver is installed (in my case using a gentoo overlay from maggu2810) you can start the displaylink service with systemctl and add the "evdi" to /etc/modules-load/evdi.conf.
By guessing that you now loaded evdi and started the displaylink service automatically, you may not be able to guess what the display device is called using xrandr. The output and steps for my 3 monitor setup, both connected via HDMI on the D3100 is here:
Code:
% xrandr --listproviders
Providers: number : 3
Provider 0: id: 0x94 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 4 associated providers: 2 name:Intel
Provider 1: id: 0x6c cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
Provider 2: id: 0x41 cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
Code:
% xrandr -q
Screen 0: minimum 8 x 8, current 5760 x 1080, maximum 32767 x 32767
eDP1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 409mm x 230mm
1920x1080 60.00*+
1400x1050 59.98
1280x1024 60.02
1280x960 60.00
1024x768 60.00
800x600 60.32 56.25
640x480 59.94
DP1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
Now after setting the provider source:
Code:
xrandr --setprovideroutputsource 1 0
xrandr --setprovideroutputsource 2 0
I can see new devices in xrandr (DVI-2-1 and DVI-1-0):
Code:
% xrandr -q

And finally use those monitors:
Code:
xrandr --output DVI-1-0 --auto --right-of eDP1
xrandr --output DVI-2-1 --auto --left-of eDP1
