Hi Xorg Team !
I'm the network administrator of a French High school and I'm face of
a new problem since the integration of XRandr in Debian Stretch.
Many of my Debian Stretch stations are teacher's desktop. Each of them
are connected to a screen and to an interactive projector. I would
like that the displays are mirrored with the best common resolution.
But the problem is that :
-> Not all station are the same model. So XRandr does not give always
the same name to the outputs.
-> The screen and the projector are not always connected to the same
display ports (VGA, HDMI, ... )
-> The screen and projector sizes varies. So Xrandr don't always
select the same resolution by default.
-> Not all graphic cards support the same display resolutions.
So actually I need to make a custom Xorg config file for all my
stations individually. For each station :
-> I need to identify the output's name of the screen and of the projector
-> I need to list the supported resolutions for each output
-> I need to choose the best match resolution
-> And finally I need to I add a config file like this :
Section "Monitor"
Identifier "HDMI-1"
Option "Primary" "true"
Option "PreferredMode" "1280x1024"
EndSection
Section "Monitor"
Identifier "VGA-1"
Option "Position" "0 0"
Option "PreferredMode" "1280x1024"
EndSection
Is there a way to make Xorg mirror screens by default and choose
itself the best resolution ? Ideally a config file that I can deploy
in all my teacher's station.
If someone can help me !
Thanks !
Baptiste.
