Shoot. I would really like a snippet for v3. I guess the last thing to try is:
i tried the above snippet (again) and couldn't get it run.
because I can't imagine MatchVendor would work. What I'm thinking is MatchDevicePath only works on the input subsystem. In other words the path has to be /dev/input/something which is why /dev/ttyS0 isn't working. The documentation (what little there is) doesn't say that, but it is the only thing that makes sense.
Identifier "Wacom legacy serial class"
Option "ForceDevice" "Serial"
For a lark you could try MatchDevice "/dev/ttyS0" as the only match. I thought I read that one somewhere but I can't find it now. The only new match I'm sure they added was MatchDriver for Xserver 1.10. If you try MatchDevice be sure to back up your current working 50-wacom.conf so you can restore it if MatchDevice breaks X. I guess I'll have to try and find the .fdi we were using in HAL. But I don't think there is a direct translation from that match to a xorg.conf.d Match.
What Mode is your tablet in, Relative or Absolute? The pressure fix for 0.10.7 was:
Unfortunately we maybe introduced a bug: In Gimp when I draw with the tablet the pressure curve works like intended till you force the pen quite hard on the tablet (I would say it's max pressure). If I do that the stroke stops drawing until I loosen it a bit again than it continuous. So Max pressure = 0 ClickForce.
Sure you can adjust ClickForce. The default is 27. At some point they normalized all pressure levels to 0 - 2047 regardless of what the hardware reports. So I think you could increase ClickForce all the way to 2047 if you wanted.
In relative mode, subtract the old pressure value from the new one.
Otherwise the pressure builds up to the maximum and stays there, even when the pen is lifted off the tablet. Same goes for tilt, wheel and rotation/throttle
The bug could be from the serial code but it is at least as likely to be in the driver code. The 0.10.x series was not suppose to be for general user use. That is the code cleanup and feature subtract and add series tree. 0.11.0, which just came out, was suppose to be the first version for general user testing. Because it is suppose to be nearly feature complete and more bug free. In other words more stable code.
xsetwacom set "stylus" ClickForce "54"
Maybe timonoko or someone else could tell us if they are seeing it with 0.10.6? Or in Lucid in case it is a Maverick thing.
Probably it would be good to test 10.6 and 10.7 v1 if the bug is here, too.
Edit: Oh, and did I guess correctly? Your Digitizer II is a UD-0608-A?
