I have two displays that I need to use with the machine: an always-on 4:3 monitor connected via DVI and an "off-when-not-actively watching a movie" 16:9 projector connected via HDMI.
Currently I run this as a Startup Application whenever the media account logs into its desktop:
Code: Select all
xrandr --output DVI-I-1 --same-as HDMI-0 xrandr --output DVI-I-1 --auto --scale-from 1280x720 --output HDMI-0
My problem is that turning off the projector causes the current solution I have to break. The projector ceases to be the primary display and stops being detected, which causes the mirroring to end and the monitor to stop being scaled. Simply running the above commands when I've turned the projector back on does *not* fix the displays.
How can I get this working?
