Sorting out input devices 2.

I didn't experience the cursor jumping jet today.
What I did today was

~$ sudo gedit /usr/lib/X11/xorg.conf.d/10-wacom.conf

now it looks like:

Section "InputClass"
Identifier "Wacom serial class"
MatchProduct "Serial Wacom Tablet"
MatchDevicePath "/dev/ttyS0"
Driver "wacom"
# Option "Device""/dev/ttyS0"
# Option "Type" "stylus"
Option "ForceDevice" "ISDV4"
Option "Button2" "3"
# Option "Button3" "4"
Option "TPCButton" "on"
EndSection

Section "InputClass"
Identifier "Wacom serial class"
MatchProduct "Serial Wacom Tablet eraser"
MatchDevicePath "/dev/ttyS0"
Driver "wacom"
# Option "Device""/dev/ttyS0"
# Option "Type" "eraser"
Option "ForceDevice" "ISDV4"
Option "TPCButton" "on"
EndSection

And works just right. We'll see what's gonna happen with the jumping.
What I basically did here was to add eraser and add proper device path, and remove unnecessary entries, like the one for supporting touch, and another one, which I don't know what it was for.

I didn't try removing the #-s jet. I jus put them in in case I want to adjust the file further to match what xorg.conf used to be before Lucid.
