Re: setting X11 screen resolution on boot

Crystal, thanks for the suggestion, but that didn't work either.

However, I found a simpler way of doing it: Add the line

${exec_prefix}/bin/xrandr --size 1600x900

with whatever screen resolution you desire, to the file

/etc/X11/xenodm/Xsetup_0

and restart xenodm.  (Get acceptable resolutions using

xrandr or lxrandr.)

You probably want something like:

Section "Monitor"
Identifier "HDMI-2"
Modeline "1600x1200_60.00"  161.00  1600 1712 1880 2160  1200 1203 1207 1245 -hsync +vsync
Option "PreferredMode" "1600x1200_60.00"
EndSection

The Identifier should be the port that the display is actually connected to,
which you can find out with xrandr.

And obviously don't use those specific line timings, but use
/usr/X11R6/bin/gtf or /usr/X11R6/bin/cvt to generate suitable timings for your
hardware.
