Bug 84656

I fixed the crash with a new "InputClass" section in my X.Org X Server configuration:

Section "InputClass"
    Identifier  "Wacom device"
    MatchVendor "Wacom|WACOM"
    Driver      "wacom"
EndSection

Still a bug in synaptics, it certainly shouldn't crash. Reopening.

please run evemu-describe against the Wacom Bamboo Pen Finger device and attach the output here. Thanks.

evemu-describe for Wacom Bamboo Pen Finger device

Huh, what's going on here. ABS_MT_SLOT, but no ABS_MT_POSITION_X? That's not a homebrew kernel or something, is it?

Really looks like a wacom kernel issue, maybe jason knows more

It is a Vanilla kernel 3.17.0 with a few patches applied from Arch Linux [core] repository.

if it's 3.17 that could be the recent wacom cleanup patches. Benjamin?

Well, it look like the new wacom driver does not like your device :(

Can you attach a hid-recorder[1] trace of all of the wacom devices it finds on your setup? (when Xorg does not crash).

There is no "hidraw" module on my kernel. The kernel config you can see here: https://projects.archlinux.org/svntogit/packages.git/tree/trunk/config.x86_64?h=packages/linux

I have no device node like /dev/hidrawN.
hid-recorder only shows a USAGE message, but no trace.

I've figured out that X.org Server only crash when I use this config section:

Section "InputClass"
        Identifier "touchpad"
        Driver "synaptics"
        MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"
	Option "VertEdgeScroll" "true"
	Option "HorizEdgeScroll" "true"
	Option "CornerCoasting" "true"
        Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"
        Option "SecondarySoftButtonAreas" "58% 0 0 8% 42% 58% 0 8%"
EndSection

It looks like 'MatchIsTouchpad "on"' matches the Wacom Bamboo Pen Finger device, too.

PS: I removed the additional Section mentioned in comment #2.

don't worry about the xorg.conf, this is a kernel issue. Do you know the last kernel version that worked for you?

You don't have a /dev/hidraw0 or something? Note that the N must be replaced with the number of your device, try them all to find the right one.

I rarely use the Wacom Bamboo at my notebook. The last time I used it was fall 2013, around Kernel version 3.11 or 3.10.

There is no device node that begins with hidraw in /dev/ (or in its subfolders).

Note: It's a Wacom Bamboo without touchpad support.

Not having a hidraw node while your device is plugged is rather worrying (your kernel is compiled with HIDRAW=Y). Can we also have a look at the dmesg when the device is plugged?

Sorry for the lag.

The bug has actually been fixed in the kernel v3.19 for Bamboo Pen CTL460 (product ID 0x00d4).

Please try a v3.19 or v4.0-rc series and close the bug if your device now works properly.

Actually, if it works, the bug should be closed as a duplicate of bug #88903
