The xrandr command, which allows you to rotate the screen, doesn't seem to have any command line options which automatically rotate 90 degrees at a time.  So I wrote a script to check the current status of the screen rotation and rotate 90 degrees from there, so that I could bind the "rotate screen" button to do the same thing it does under sugar.  While I was at it, I set up a script to rotate in the opposite direction, so that you don't have to push the rotate button three times to rotate 270 degrees clockwise if you just want to rotate 90 degrees counter-clockwise.

Script to rotate clockwise, which I put in /usr/bin/xrandr_rotate.sh

current=`xrandr | grep connected | awk '{print $4}'`
if [ $current == "(normal" ]; then val=1
  elif [ $current == "left" ]; then val=2
  elif [ $current == "inverted" ]; then val=3
  elif [ $current == "right" ]; then val=0
fi

xrandr -o $val


Script to rotate counter-clockwise, which I put in /usr/bin/xrandr_reverse.sh

current=`xrandr | grep connected | awk '{print $4}'`
if [ $current == "(normal" ]; then val=3
  elif [ $current == "left" ]; then val=0
  elif [ $current == "inverted" ]; then val=1
  elif [ $current == "right" ]; then val=2
fi

xrandr -o $val

Make sure you make both those files executable:

su - root
chmod 755 /usr/bin/xrandr_rotate.sh
chmod 755 /usr/bin/xrandr_reverse.sh



For fluxbox, I added these key bindings in my /home/olpc/.fluxbox/keys file, to press the rotate button for clockwise rotations, or shift plus rotate button for counter clockwise rotations:

235 :ExecCommand xrandr_rotate.sh
Shift 235 :ExecCommand xrandr_reverse.sh


Under xfce or other window managers, you'll have to figure out the appropriate way to bind keys, and figure out what value the rotate button has.  But the idea will be the same.

I hope some of you find that useful; I've found this forum and the other OLPC info-spots around the web very very helpful as I've customized this thing for myself!

Hey, Scrub!

the best "achieve-my-goals-as-soon-as-possible" solution that i've found
