running 12.04 on my Thinkpad X201t. On the login screen the touch works fine, the mouse cursor appears where I touch the screen. After I logged in, it doesn't work anymore. If I touch the display, the cursor stays on the point where it was before, it doesn't jump to the touchpoint. I can move it, yes, but its chaotic. With the pen it works fine, but without the touch-function it's not enought for real tablet usage. So, would be glad if touch-function can be fixed. I'm very new to Linux/Ubuntu, so don't know where I can start. Haven't found anything in the system settings & Compiz so far, also no luck in google etc. Would be glad for help ;-). Of course I could go back to 11.04... but I would prefer to stay with the new system.

Best, Joachim
