Default working wacom hotplug available for testing


During the intrepid timecycle we got input-hotplug, but it only handled
mice, touchpads and keyboards properly. Wacom tablets were problematic,
since the normal method of hooking up a driver to a specific device with
the help of hal only worked with a single logical device. Wacom tablets
usually have several "devices" with different roles that used to open the
driver separately, and that was not possible at that time.

Now for jaunty, there's a new wacom-tools in my PPA which should do proper
input hotplugging by using a hal callout program to set up the extra
devices that the fdi file lists the hardware should support. It should
also work on builtin serial devices like on tablet laptops. The patches,
including some bugfixes, are borrowed from Fedora.

So, please test and feel free to file bugs on launchpad against
wacom-tools. Just make sure to mention that it's the PPA version of the


No promises that it'll get in jaunty, but if the testing proves positive
the X-SWAT team will likely file a FFe bug for it.

ps. one upstream commit from has been reverted from the package,
because it broke my cheap Waltop tablet. If you lucky b......s with a
proper wacom see something like

usbParse: Exceeded channel count; ignoring the events

in the xorg log, let me know (via launchpad, of course)
