Hello I have been trying to setup a second monitor for my laptop under Ubuntu 18.04 and I can't seem to be able to scale the second monitor properly.
My monitors are :
- XPS 15 4k built-in display (3840x2160)
- Dell 24" (2560x1440)
As most people using 4K resolution on a 15" display, I scaled the display to 200% using GNOME. The issue comes from the fact that gnome cannot scale different displays in different ways. So when I hook up my other monitor I get a zoom to important on my 24" monitor.
Aster looking online for a while I tried using arandr to no avail and I then stumbled upon this post.
It explains very well how to set up 2 displays using XrandR. Unfortunately It seems not to work for my problem.
Given that I want my second monitor on the left of my laptop screen and that my xrandr -q returns :
Screen 0: minimum 320 x 200, current 6400 x 2160, maximum 8192 x 8192

Here is what I tried :
xrandr --output DP-1-1 --scale 2x2 --fb 6400x2160 --pos 0x0
xrandr --output eDP-1 --scale 1x1 --pos 2560x0
Unfortunatly here is what it gives:
xrandr: specified screen 6400x2160 not large enough for output DP-1-1 (5120x2880+0+0)
And I get my 2 displays overlapping.
It's really been messing with me lately so if any of you have any idea how to fix this it would be greatly appreciated.
Thank you.
