Description of problem: Today I upgraded the kernel from kernel-2.6.16-1.2133_FC5 to kernel-2.6.17-1.2139_FC5. When I did so, the direction of travel associated with my mouse wheel reversed itself. Now, when I move the mouse wheel in a downward direction, the scrollbars move up! I am using a Wacom USB graphics tablet. This uses the "wacom" kernel driver. The tablet comes with both a pen and a mouse. The pen works as normal, and the mouse works apart from the oddity with the wheel. Version-Release number of selected component (if applicable): I am using linuxwacom-0.7.2-1.2 but as the problem was brought on by the kernel upgrade, I assume it is kernel related. Reverting to the old kernel cures the problem. How reproducible: Always. Steps to Reproduce: 1. Attach a Wacom tablet to your computer and configure it in xorg.conf. 2. Install kernel-2.6.17-1.2139_FC5. 3. Start X. 4. Observe that the mouse wheel moves scrollbars the wrong way. 5. Revert to kernel-2.6.16-1.2133_FC5. 6. Observe that the mouse wheel works correctly. Actual results: Moving the mouse wheel down moves scrollbars up. Expected results: Moving the mouse wheel should move scrollbars in the same direction. Additional info:
My tablet (a Wacom Volito USB) completly stopped working after the latest upgrade. In dmesg I found only one line mentioning the loading of the Graphire/Intuos driver, but the Wacom tablet does not respond at all.
I just remembered something I forgot to say in my original report. I tried reversing the order of the numbers in the ZAxisMapping. I expected that to reverse the direction and get things back to normal, but in fact it made no difference at all.
Johan, that's very interesting, but it seems not very relevant. Also, please refrain from using words "latest" and "current" when referring to release numbers.
(In reply to comment #3) > Johan, that's very interesting, but it seems not very relevant. > Also, please refrain from using words "latest" and "current" when > referring to release numbers. Sorry about that. I will try to collect more information about that issue and file it in more relevant place.
FYI, this is still a problem with kernel-2.6.17-1.2145_FC5. (I'm not sure if there are actually any changes to the Wacom driver in this release, but I thought I'd let you know just in case.)
I didn't do anything, sorry. It's on my list.
I've managed to get my own system working now. What you have to do is download the latest linuxwacom (0.7.4-3) from http://linuxwacom.sourceforge.net/. The tar file contains a directory called prebuilt, and in there is a file called wacom_drv.so. wacom_drv.so is a module which is meant to be loaded into the X server. Replacing the Fedora-supplied wacom_drv.so with the one from the tar file fixes the problem. (Building the driver from source, rather than using the prebuilt driver, works as well.) Presumably, after the kernel update, there was a mismatch between the kernel Wacom driver, and the X server one.
I contacted Dmitry and he thinks it may be a regression. I can plainly see where Ping got it wrong in the patch. Currently, we're waiting on Ping to make the determination. So, I'm not going to throw this bug over to Kristian. I'll just add him on cc:, so he knows that the issue exists.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.
Unfortunately the problem seems to have got worse. The workaround in comment 7 no longer works (and it doesn't work if I return to the Fedora-supplied Wacom driver, either). As well as the mouse wheel, there now seem to be problems setting the tablet options, like absolute versus relative positioning.
I just upgraded to FC6 and the Wacom tablet is now working perfectly. I think it may have worked with the new FC5 kernel after all, actually. I had been testing by booting up as normal, switching to a text console and making changes to xorg.conf, and then running "xinit -- :1". When setting the tablet up with FC6, I discovered that this doesn't work. Only the first X server seems to be able to make configuration changes to the tablet.
