Good news. We have a linux wacom developer willing to help us. I posted Connor's annotated Xorg.0.log and Chris Bagwell said:
"For first bug report, it does sound same issue as I looked into a while back. The kernel driver is mistakenly telling userland that the PAD device has gone out of proximity when you use pen. From that point, buttons don't work.
Something has changed in xf86-input-wacom that we must l trust kernel information more then we used to. My personal reference is to fix the kernel to give us good info instead of reverting back to old xf86-input-wacom behavior.
...
Or hopefully we can find a user that doesn't mind hacking kernel drivers. I can give tons of guidance on patch to implement (its like 3 lines for simple solution) but ultimately I can't push forward much more since I don't have the device."
Chris is saying likely minimal changes are needed to wacom_wac.c in the kernel in order to fix this issue. And getting the Ubuntu kernel source code to patch is easy, as is compiling it. If you don't know how look in Appendix 1 at this HOW TO: http://
So if you're interested in helping with this issue and have a Graphire4 or other tablet with this issue (presumably because it also uses the Graphire logic) please join the discussion on linuxwacom-discuss: https:/
