Hullo,

I've got a Wacom Graphire graphics tablet which I'm using on Gentoo
Linux under XFree 4.3.99. The kernel HID/InputCore stuff is set to
1600x1200 as is my desktop. It works but in absolute mode it isn't
actually absolute.

It pretends to be. The area of the pad corresponds to an area on the
screen but the *origin* appears to float. eg move pointer to bottom of
screen and find it hits the 'wall' before the bottom. Move pointer to
top of screen and it hits the top before hitting top of pad. Continue
mouse to to top of pad and then go to bottom again and this time it hits
the bottom. I thought that in absolute mode the position on the pad was
supposed to correspond to the position on the screen.

Also the pointer 'jiggles' by a few pixels as if the mouse was shaking
(which it obviously isn't).

This happens with mouse and stylus. There is a normal mouse attached to
the system but it isn't moving whilst the the pad is being used.

Any ideas? Any config I'm mucking up? Here's the relevant XFree86
config:

Section "InputDevice"
        Identifier "cursor"
        Driver "wacom"
        Option "Device" "/dev/input/event0"
        Option "Type" "cursor"
        Option "Mode" "absolute"
        Option "Speed" "3.5"
        Option "ZAxisMapping" "4 5"
        Option "USB" "on"
        Option "Threshold" "10"
EndSection

Section "InputDevice"
        Identifier "stylus"
        Driver "wacom"
        Option "Device" "/dev/input/event0"
        Option "Type" "stylus"
        Option "Mode" "absolute"
        Option "USB" "on"
        Option "Tilt" "on"
        Option "TiltInvert" "on"
        Option "Threshold" "10"
EndSection

Section "InputDevice"
        Identifier "eraser"
        Driver "wacom"
        Option "Device" "/dev/input/event0"
        Option "Type" "eraser"
        Option "Mode" "absolute"
        Option "USB" "on"
        Option "Tilt" "on"
        Option "TiltInvert" "on"
        Option "Threshold" "10"
EndSection

Cheers,
