I have a X41 Tablet here as well and tried to apply your patch - I also had to modify some of the header files to include xorgVersion.h and xorg-server.h instead of the XF86 stuff. It compiled fine but after modifying the kernel (nasty stuff in the howto) and starting X, the machine crashed immediately after the pen hits the display for the first time. I would be happy to help out and test code - but my C knowledge is reduced to the easy modifications mentioned above... -- Oliver PETER email: oli...@peter.de.com ICQ# 113969174 "I'm just a simple man trying to make my way in the universe." -- Jango Fett
