[Linuxwacom-discuss] Mdk9.1, wacom 0.4.1 install problems: strangeness abounds

[Wade B. <wad...@ve...>]

Well this is a bummer. Linux-wacom installed without a hitch this spring
when I installed it on Mandrake 9.0. Now that I'm on 9.1, not so
lucky...

In a nutshell, I seem to be able to get either wacdump or xidump to read
the tablet correctly, but not both at the same time. The mechanism that
makes one work vs the other is if I have the tablet (Graphire2) plugged
in when I restart X. Unplugged, wacdump will work. Plugged in, xidump
will work, but only in the raw mode, not curses. This is with
linuxwacom-0.4.1.

Potential issues:
-/var/log/messages is slightly different than the examples given in the
HOW-TO. I've got usbmouse and evdev thrown into the mix. The lines are
listed below in case#2
-My XF86Conig-4 file does contain a Mouse1 as the CorePointer, but its
the only Mouse section and its a PS/2 mouse, not a USB.

Any suggestions would be appreciated. Three debug scenarios I've gone
through are listed below for referance.

All cases seem to read x/y ok
Pressure has a problem
1. Restart X server with Graphire2 plugged in
-wacdump doesn't read any pressure values
-xidump stylus curses doesn't read any pressure values
-xidump stylus raw reads pressure correctly

2. Unplug and reconnect Graphire2 doesn't read

3. Unplug Graphire, restart X, connect Graphire

-wacdump correctly reads pressure values
-xidump stylus curses is completely dead, no response, not even X/Y
-xidump stylus raw is also completely dead,

4. Build and install hid.o and usbmouse.o. Restart X without tablet
connected, reconnect tablet.

-wacdump correctly reads pressure values
-xidump stylus curses is completely dead, no response, not even X/Y
-xidump stylus raw is also completely dead,

5. Now restart X with the table still plugged in (new hid.o and
usbmouse.o)

-wacdump doesn't read any pressure values
-xidump stylus curses doesn't read any pressure values
-xidump stylus raw reads pressure correctly
