Wacom Graphire acts strangely on Edgy PowerPC, no /dev/wacom

Same problem on an out-of-the-box Ubuntu 6.06 64-bit. Wacom tablet is CTF-420.

Occasionally the cursor can be moved around the whole screen. But often it cannot reach the top and/or left side of the screen. The movement ends at about 90% of the whole screen (but this is not always the location). Rarely it cannot reach the right side either, but just by a few millimeter.

please test again with the wacom-tools 0.7.7.7. make sure to change the device in xorg.conf to /dev/input/wacom

Sorry for the late reply, I had no time for Linux fiddling in a while.

Installing 0.7.7-11 under Ubuntu 6.06 worked fine. Since the "Ubuntu
success story" does not describe this well, I add a little How To below.

The driver works very much better, thanks for the good work. It is now
in state where I can use it.

Unfortunately, the bug with the "invisible wall" (where the cursor does
not move beyond a certain vertical or horizontal line) is NOT 100%
fixed. So far I never had it at the top or bottom of the screen. But it
happened once on the right hand (just a few millimeter away from the
edge - but enough to make a scroll-bar unreachable). And it happens
quite frequently on the left side usually between 2 and 5 cm into the
screen.

My setup includes a relatively large screen (1920x1200). A bit special
about my setup is also, that I run a trackball together with the tablet
(and even two more pointing devices: a touchpad and the little red stick
on an IBM keyboard). All on an AMD 64 bit Ubuntu 6.06 Linux.

Howto install 0.7.7-11 under Ubuntu 6.06 (a 2.6.15 kernel):

Download from
http://prdownloads.sourceforge.net/linuxwacom/linuxwacom-0.7.7-11.tar.bz2
and unpack.

Besides the correct kernel sources, one needs to download several more
"Something-dev" packages. To find out which ones I simply ran

./configure --enable-wacom

where I unpacked the driver. The error messages about missing files are
fairly clear. I think I missed (from memory):

ncurses-XX-dev
xorg-XX-dev
tcl-XX-dev
tk-XX-dev

(where XX is the latest version). After all were downloaded (and lots of
dependent packages), configure ran through without error. Then simply do

make

For Ubuntu 6.06 one only needs the file wacom.ko, the "hid" file seems
unnecessary (at least for me).

Move the old version of wacom.ko

/lib/modules/2.6.XXX/kernel/drivers/usb/input/wacom.ko

to a safe place (XXX is the kernel version, in my case a 64 bit
2.6.15.something) and move the new one in its place. Reboot and enjoy.

I understand this has been fixed a long ago. Closing the bug.
