DisplayLink displays on Ubuntu can be managed through the Ubuntu System settings. The screen settings can be found under the Displays section of the Ubuntu settings:
The display layout can be changed to match the physical layout of the displays or set to extend or mirror other displays.
xrandr use: These layouts can be be also modified using the command xrandr from a Terminal – however xrandr does not work on Wayland. On X11 xrand works as in previous Ubuntu versions, on Wayland it can only print information about displays. Note that under X11 DisplayLink displays will always show up as connected through DVI
xrandr enables the layout or screen resolution to be set. Eg:
- Set the resolution:
xrandr --output DVI-1-0 --mode 1680x1050
- Set the position:
xrandr --output DVI-1-0 --left-of DVI-2-1
