Unplugging USB tablet crashes xserver

[Alexey Spiridonov]

Binary package hint: xserver-xorg-input-aiptek

This is exactly the same as
  https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-aiptek/+bug/355021

For some reason, it was decided that the old bug was fixed.

I have 10.04 LTS / X 1.7.6 / aiptek 1.3.0, so everything is up-to-date.

Repro steps:

0. Set up as at https://help.ubuntu.com/community/AiptekTablet
1. Stop X.
2. Plug in tablet.
3. Verify that tablet works via "cat /dev/input/aiptektablet" and observing characters on the screen.
4. sudo service gdm start
5. Observe that tablet moves mouse cursor
6. Unplug tablet.
7. Observe that X just crashed, and restarted with a brand-new GDM login screen.

I'll be attaching the X log, which includes a backtrace from the driver.

please run 'apport-collect 793338' after the crash.

[Timo Aaltonen (tjaalton)]

also wondering if it would just work with the wacom driver on 11.04, like aiptek 10000U et al. (though you'd need to edit /usr/share/X11/xorg.conf.d/50-wacom.conf to load it for Aiptek)

There you go!

I'm not keen on updating releases any sooner than I have to. It's nice not to have to adjust my workflow in random ways every 6 months. I use Lucid both at home and at work, which makes it a second reason not to upgrade.

Do you have a link with instructions for 11.04? I can try it off a LiveCD if it looks easy. I see no mention of 11.04 here: https://help.ubuntu.com/community/AiptekTablet

[Timo Aaltonen (tjaalton)]

There is a new upstream release (1.4.1) that should fix this bug, it'll get in oneiric soon. It requires xserver 1.10 though, so a direct backport to anything older than natty is not possible.

[Timo Aaltonen (tjaalton)]

the new driver is now in oneiric.
