I recently got a Zenbook Prime and installed ubuntu. Following The tips at https://help.ubuntu.com/community/AsusZenbook worked out pretty well.
Only one problem remains: I can not set the DPI.
I tried to do
xrandr --dpi 138/eDP1 but that doesn't seem to have the desired effect.
It changes the output of
xdpyinfo |grep resolution but no change is visible.
Also, xrandr still reports the same screen size.
I tried adding
Xft.dpi: 138 to
.Xresources, which didn't change anything.
I also tried to generate a xorg.conf, where I set
Option "DPI" "138 x 138"
in the monitor section. The Xorg.0.log then tells me
(==) intel(0): DPI set to (96, 96) ... (WW) intel(0): Option "DPI" is not used
I have no idea what else to try and it doesn't seem any one else has the same problem :(
Any help would be much appreciated.
PS: I know that it is possible to zoom fonts, but I'd rather actually set the DPI of the screen.
