It should be possible but I can't think of an elegant way atm. You could periodically check if a certain string is still

1440x900       59.9*+   59.9*

, if not then ...
Happy parsing.

k! that string it is from ???????? xrandr?

Yeah, it's the output of 'xrandr'.

I did something else

I use inotifywait from inotify-tools to watch the Xorg log if something modifies the log.

#!/bin/sh

path="/var/log/Xorg.0.log"
OldRes=$( xrandr | grep '*' | awk '{print $1}' )

while [ 1 ]
   do
      EVENT=$(inotifywait -e modify $path)
      NewRes=$(cat $path | tail -n 1 | grep -i "Allocate new frame buffer" | awk '{printf $7}') 
      if [ -n "$NewRes" -a "$NewRes"="$OldRes" ] ; then
         echo "The Screen Resolution has changed " "$NewRes"
         OldRes=$NewRes
      fi
   done

So now I can resize some stuff when I change the resolution xd ....
someone knows another way?
