I am using a Lenovo Thinkpad X220T tablet with twisting monitor. I usually turn the monitor, rotate the screen and disable the finger touch to use the pen, and I did this through an script and mapping a shortkey to it. It worked all fine until yesterday that I updated my Ubuntu 13.04. After playing around with it here is what I have:
xrandr --output LVDS-0 --rotate inverted
does rotate the mouse pointer icon and its orientation, but that's it. Nothing else changes.
I also tried
xrandr -o inverted which does exactly same thing.
PS: A couple months ago I had this problem that whenever I turn on the computer the monitor would be rotated right, so I added a line to
xorg.config that simply said change the rotation of the monitors to "normal". I thought that might be causing the problems after the updates, and restored the xorg.conf to old configuration, but that also didn't help.
