[intrepid] graphire bluetooth works until pressure reaches "64"

[tommy]

Binary package hint: wacom-tools

Ubuntu 8.10 RC (updated) AMD64
wacom-tools 1:0.8.1.4-0ubuntu3

Using the same modified hidp kernel module as I used successfully in hardy, I have my graphire bluetooth sending the correct data (as indicated by xidump), and working correctly until the pen pressure exceeds "+00063". The maximum value is correctly reported by xidump as +00511.

When the pressure value exceeds 63, input from the tablet locks up until the pen is moved out of range of the tablet. When moved back in range it works as before. Other input sources are not affected.

I don't really know where to begin tracking down the cause of this :/.

When I run wacdump outside of X, the pressure value is reported up until the maximum value of 511, so the tablet and the modified hidp module seem to be working.

I tried editing my xorg.conf as indicated in https://help.ubuntu.com/community/WacomTroubleshooting and removing the 10-wacom.fdi file from /usr/share/hal/fdi/policy/20thirdparty. The result was similar, except when pressure exceeded 63 the cursor became enormously sensitive to movement, and completely lost pressure sensitivity (until the pen was moved out of range, as before).

I've just installed the latest version of the linux wacom drivers (linuxwacom 0.8.1-6) and this problem seems to be fixed. The tablet is working fine now.

Hi yobbobandana,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

Tommy, thanks for letting us know the issue is fixed now.

Sorry, I should have clarified:

The issue is fixed upstream with version 0.8.1-6 of the linux wacom drivers. It is not yet fixed in intrepid, which still uses version 0.8.1-4.

It seems to be the same as the "cursor freezes when clicking the tablet" bug that some people are experiencing, and I've read of people on the forums experiencing this bug when clicking too.

I think these bugs might stem from the same problem:
