Xrandr in Xinitrc stopped working with new monitor

Hi all,

I have a weird problem I don't know how to solve.

I have external monitor connected to my laptop and for a long time had in my xinitrc line like that:

xrandr --output eDP1 --off --output DP2-1 --primary --mode 2560x1440

Now I'v changed monitor to ultrawide and:

xrandr --output eDP1 --off --output DP2-1 --primary --mode 3440x1440

has no effect. Not only DP2-1 has 2560x1440 resolution but also eDP1 is turned ON.

If I copy xrandr command and run in terminal it works just fine.

It looks like my .xinitrc can't propery run modified xrandr command.

.xinitrc

Re: Xrandr in Xinitrc stopped working with new monitor

Try to replace the call w/ two calls

xrandr --output DP2-1 --primary --auto
xrandr --output eDP1 --off 

(skip the entire configuration trying to turn off non existent outputs)

Semi-related: you might want to utilize some /etc/X11/xorg.conf.d/11-monitor.conf

Section "Monitor"
	Identifier "DP2-1"
#	Option	"Enable"	"False"
	Option	"Primary"	"True"
EndSection

Section "Monitor"
	Identifier "eDP1"
#	Option	"Primary"	"True"
	Option	"Enable"	"False"
EndSection

instead.

Unrelated but relevant: click the 4th link in my signature ;-)
