does the tablet send the right output if you run "xinput --test <device name>"? you can get the device name with xinput --list. each value printed refers to one of the axes, IIRC it's x, y, pressure, tilt x, tilt y xinput --test "Wacom Intuos3 6x8 cursor"
or
xinput --test 12
does not produce any output in konsole
Here is full output:
xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Macintosh mouse button emulation id=7 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=8 [slave pointer (2)]
⎜ ↳ Genius Optical Mouse id=10 [slave pointer (2)]
⎜ ↳ Wacom Intuos3 6x8 eraser id=11 [slave pointer (2)]
⎜ ↳ Wacom Intuos3 6x8 cursor id=12 [slave pointer (2)]
⎜ ↳ Wacom Intuos3 6x8 pad id=13 [slave pointer (2)]
⎜ ↳ Wacom Intuos3 6x8 id=14 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]

One observation about Qt and tablets:
People claim that Qt uses xlsatoms for detecting tablet.
see qt/src/gui/kernel/qapplication_x11.cpp line 318 in Qt4.6.x
Another user used to have older version of the driver xorg-x11-drv-wacom and the cmd "xlsatoms | grep Wacom" he used to have 3-4 entries in there, but after the update, similar list to my list. Longer list, not working tablet pressure in Qt apps. - on Arch linux though.
Is there any sense to try to compile linuxwacom project to update the kernel driver? I doubt but I'm trying to suggest something so that I can fix that.
I tried the linuxwacom 0.8.4-4 but probably due to X Server 1.7.5 in Fedora it failed as it suppose to work up to 1.6.x
(In reply to comment #2) > xinput --test "Wacom Intuos3 6x8 cursor" the cursor device is the mouse device that wacom supplies as an extra to some tablets. the stylus is the "Wacom Intuos3 6x8" in your case (device 14). Please try that one too. reassigning to qt.
qt checks for hardcoded type names to see if a wacom device is present. these atom names are
"Wacom Stylus\0"
"Wacom Cursor\0"
"Wacom Eraser\0"
see qt source, qapplication_x11.cpp:316
xorg-x11-drv-wacom fixed a bug in assigning these names where the device would overwrite itself and mess up the device names. The type names used now are "STYLUS", "CURSOR", "ERASER", "PAD" and "TOUCH" for each respective device. qt hence doesn't find the devices anymore and it appears that no device is available even though the device itself is working.
qt should check for these new type names instead of the ones above.
I think openSUSE has been carrying a Qt patch for that or something similar for a while, we need to check it. @Kevin: I investigated this package http://download.opensuse.org/source/factory/repo/oss/suse/src/libqt4-4.6.2-1.3.src.rpm I copied the patches from CONTENTS.cpio and I was greping for qapplication_x11 and tablet and stylus. But I did not find anything related. Btw OpenSUSE 11.2 uses still X server 1.6.x and linuxwacom driver.So probably they don't patch yet. Qt is 4.6 there.

This worked, example output: motion a[0]=21453 a[1]=19048 a[2]=0 a[3]=42 a[4]=-7 a[5]=0 motion a[0]=21534 a[1]=19082 a[2]=0 a[3]=40 a[4]=-7 a[5]=0 motion a[0]=21628 a[1]=19111 a[2]=0 a[3]=37 a[4]=-7 a[5]=0 motion a[0]=21722 a[1]=19137 a[2]=0 a[3]=33 a[4]=-7 a[5]=0 motion a[0]=21814 a[1]=19159 a[2]=0 a[3]=30 a[4]=-7 a[5]=0 motion a[0]=21901 a[1]=19182 a[2]=0 a[3]=26 a[4]=-7 a[5]=0 motion a[0]=21986 a[1]=19204 a[2]=0 a[3]=22 a[4]=-6 a[5]=0 ... Seems like pressure and tilt work. (In reply to comment #5) > I think openSUSE has been carrying a Qt patch for that or something similar for > a while, we need to check it. No, not yet for Qt 4.x Confirming this on TabletPC hp tx2500z. Pen has no sensitivity in Qt applications. I'm on Fedora 12 - 2.6.32.8-58.fc12.x86_64, KDE 4.4.0, Qt 4.6.2, xorg-x11-drv-wacom-0.10.4-2, all 64bit. it should be fixed in qt-4_6_2-5_fc12 Confirming, pressure sensitivity works again in Krita, thanks :) qt-4.6.2-7.fc13 has been submitted as an update for Fedora 13. http://admin.fedoraproject.org/updates/qt-4.6.2-7.fc13 qt-4.6.2-7.fc12 has been submitted as an update for Fedora 12. http://admin.fedoraproject.org/updates/qt-4.6.2-7.fc12 qt-4.6.2-7.fc12 has been pushed to the Fedora 12 testing repository.
