Without this the Wacom Graphire 4 Tablet mouse runs as smooth as silk; finest mouse I've ever had.
Background: Went back and confirmed that I had not built the 2.6.11 kernel with local APIC support. Somewhere along the line - perhaps when I ran make oldmenuconfig - this got added in the 2.6.17 kernel. It sounds like a good thing to add but not if you want to use a Wacom mouse. Notes on my other posts on this subject: xsetmode will change the pointer between Absolute and Relative. In my case changing it had no effect. I never found out if xsetwacom can change the Motion_Buffer but I did inadvertantly change its value. Mike had pointed out that in the xorg.conf entry for the wacom pad I had set /dev/input/event0 while for the stylus, eraser and cursor entries I had set /dev/input/wacom. I changed the pad entry to /dev/input/wacom and this did bad things. When I put it back to /dev/input/event0 and restarted gdm all was well again but values of all the Wacom device Motion_Buffers had changed from 256 to 0. I seem to remember that when I first set up my Wacom tablet a year ago I found information on the Wacom website that told me how to modify xorg.conf and that it specifically said the entry for pad should be event0. Note that /dev/input/wacom is a soft link to /dev/input/event2. I hope all this is helpful to someone. For myself I am as happy as a clam to have my Wacom mouse and stylus working again. When they work right there is not another mouse that comes close to their smooth, precise performance.
