Comment 3 for bug 295292

Oh, this is frustrating. I installed the latest wacom-tools (0.8.1.6, as described in the link you posted--BTW, that page should also include the --prefix=/usr option to configure, otherwise the updated driver is installed in /usr/local and isn't used). The xserver now crashes every time I rotate the display with compiz enabled (with or without the wacom pointers), as described in another bug report (https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/294309). With compiz disabled, the xserver doesn't crash, but the calibration problem remains.

Thanks for the work-around--unfortunately, this won't really work to unlock the screen (with cellwriter) after resuming from a suspend. As far as posting to the linuxwacom-discuss list--I'm afraid to subscribe to that list with the slew of spam messages that are posted. :)
