    Haha...You've got a good point. I guess it's been a while since I messed with this. However, I could have sworn, in an earlier version, the rotation worked so controlling the mouse pointer with the keyboard button didn't make it move in the opposite direction. Right now I can't think of a situation where I'd need that to work. Problem solved.

    I just picked a TC1100 out of the trash. It's a complete one with Bluetooth and keyboard. It included all the disks, manuals, nice case. and a USB DVD drive. Didn't look like it had ever been used and there was no OS on the drive (or the drive had been wiped). I thought I'd go for the latest Maverick beta, but I kept running into snags with it. I might try it again when it comes out in release.

    Lucid works great though, except for the stylus buttons on the side of the screen. No problem. They are easy enough to duplicate on the panel. I especially think that Compiz running on a seven year old laptop is pretty amazing, and the Compiz annotation tool is especially useful on a tablet PC.

    Thanks to all of you for figuring all this hard stuff out. It made it easy and mostly fun for me to get mine up and running.

    Re: HOW TO: Install Ubuntu on a HP TC1100 tablet pc

    Very strange. The pen suddenly stopped working today. I don't know what happened. I've tried a lot of things to get it working again, but no luck. I've taken a couple of software updates in the last few days, but I'm not sure that caused it. I tried completely removing and reinstalling xserver-xorg-input-wacom. Anyone else ever experience this? Any ideas?

    I still don't have pen functioning, but I think I'm a step closer. It appears that Xorg is trying to load a "Serial Wacom Table eraser" that fails. Later it tries to add "Serial Wacom Tablet" (type: STYLUS). It can't initialize either device, so it reports an error and unloads the Wacom module.

    Problem is, I can't locate where this is configured so I can comment it out. Can anyone help me?

    Here's the relevant portion of the Xorg.0.log:

    (II) config/udev: Adding input device Serial Wacom Tablet (/dev/ttyS0)
    (**) Serial Wacom Tablet: Applying InputClass "Wacom serial class"

    Randy -- I doubt that the problem has to do with the eraser. However, since the stylus works out-of-the-box I am unable to duplicate your problem. Test to make sure your hardware is working by using a livecd.

    Mi MyR,

    I can do the BIOS pen calibration, so I know the hardware still works.

    I'm just curious about what goes on in the X11 init as detailed in the log segment above. Everything seems to go right until

    (II) XINPUT: Adding extended input device "Serial Wacom Tablet eraser" (type: ERASER)

    which causes an errror, then later

    (EE) Couldn't init device "Serial Wacom Tablet eraser"
    (II) UnloadModule: "wacom"

    That just doesn't look good to me. Do you have something similar in your Xorg.0.log? Is something in X11 configured wrong, or does X get this from HAL? Any ideas how to fix?

    Cheers,
    Randy

    I hope this helps!

    You could also try to load the module manually with
    Code:
    sudo modprobe wacom

    Thanks again, but still no luck.

    The major difference in our Xorg.0.logs is that where your's shows a warning when trying to hotplug ERASER and STYLUS, mine give an error and unloads the driver. Actually, I'm not sure that the driver quite gets unloaded. If I do a "modprobe -l" I see:

    kernel/drivers/input/tablet/wacom.ko
    kernel/drivers/input/touchscreen/wacom_w8001.ko
    kernel/drivers/hid/hid-wacom.ko

    so it looks like I have drivers loaded in the kernel. Attempting

    sudo modprobe -r wacom

    doesn't remove the modules, and running modprobe again doesn't seem to change anything either.

    I'm using your xorg.conf.d/10-wacom.conf and was using it successfully for a week before the problem started.

    I'm at a loss at this point. I'd really hate to have to reinstall the OS, as I'm happy with the way everything else is set up, and it took a lot of time to get it that way.
