Thread:Beagleboard talk:BeagleBoneBlack HDMI/How to force a resolution

I followed the instructions on this page but noticed that it didn't really mention how to make the changes permanent.

This works for my Samsung LED Monitor S24D300HL.

root@beaglebone:~# tail -n6 /etc/gdm/Init/Default export XAUTHORITY=`ls /var/run/gdm/auth-for-root-*/database` export DISPLAY=:0 xrandr --output HDMI-0 --mode 1680x1050
 * 1) Use xrandr!

exit 0
