xrandr --scale on DisplayLink

Hi,

xrandr's --scale option doesn't work for me on my DisplayLink display. The screen flickers off and back on, but the scale does not change. Can anyone else confirm/deny this issue with their own hardware? Presumably this would be a bug with the DisplayLink driver? I have a Kensington SD3000v.

$ uname -r
4.7.0-1-ARCH

$ xrandr --version
xrandr program version       1.5.0
Server reports RandR version 1.5

$ yaourt -Q xorg-server

$ yaourt -Q displaylink

I have the same issue here 7 years later. Seems nobody cares

Re: xrandr --scale on DisplayLink

If you want for people to care, make a new post detailing your issues and how they present themselves 7 years later with a 7 year newer software stack instead of necrobumping
