xorg.conf.d is replacing xorg.conf. Instead of one monolithic file with hundreds of settings, you now have a separate file for each section of the settings. The effect is exactly the same, but it is simpler to manage.

I've tried to tweak my xorg.conf, but it appears that my system is using /usr/share/X11/xorg.conf.d and contains 20-wacom.conf as below:

Code:

Section "InputClass"
Identifier "Wacom class"
# WALTOP needs a patched kernel driver, that isn't in mainline lk yet,
# so for now just let it fall through and be picked up by evdev instead.
# MatchProduct "Wacom|WALTOP|WACOM"
MatchProduct "Wacom|WACOM"
MatchDevicePath "/dev/input/event*"
Driver "wacom"
EndSection

Section "InputClass"
Identifier "Wacom serial class"
MatchProduct "Serial Wacom Tablet"
Driver "wacom"
Option "ForceDevice" "ISDV4"
EndSection

Section "InputClass"
Identifier "Wacom serial class identifiers"
MatchProduct "WACf|FUJ02e5|FUJ02e7"
Driver "wacom"
EndSection

# N-Trig Duosense Electromagnetic Digitizer
Section "InputClass"
Identifier "Wacom N-Trig class"
MatchProduct "HID 1b96:0001|N-Trig Pen"
MatchDevicePath "/dev/input/event*"
Driver "wacom"
Option "Button2" "3"
EndSection

trying:
xsetwacom set "touch" Gesture "on"

doesn't work, because my device appears as 'Finger' though referring to it with that also doesn't work, but I have tried with the ID number.
I can only assume that something like the following needs to go in somewhere, but not sure whether I should be creating an xorg.conf in /etc/X11 or what:

Code:

# This section is for the TabletPC that supports touch
Section "InputDevice"
Driver "wacom"
Identifier "touch"
Option "Device" "/dev/ttyS0" # SERIAL ONLY
Option "Type" "touch"
#Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "stylus" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
InputDevice "touch" "SendCoreEvents"
EndSection

The results of xinput list:

Code:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Wacom ISDv4 E3 Finger    id=11 [slave pointer (2)]
⎜ ↳ Wacom ISDv4 E3 Pen eraser    id=12 [slave pointer (2)]
⎜ ↳ Wacom ISDv4 E3 Pen id=13 [slave pointer (2)]
⎜ ↳ Wireless Keyboard/Mouse    id=15 [slave pointer (2)]
⎜ ↳ PIXART USB OPTICAL MOUSE id=16 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=19 [slave pointer (2)]
⎣ Virtual core keyboard    id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard    id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus    id=7 [slave keyboard (3)]
↳ Video Bus    id=8 [slave keyboard (3)]
↳ Power Button id=9 [slave keyboard (3)]
↳ Sleep Button id=10 [slave keyboard (3)]
↳ Wireless Keyboard/Mouse    id=14 [slave keyboard (3)]
↳ HP Webcam    id=17 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=18 [slave keyboard (3)]
↳ HP WMI hotkeys id=20 [slave keyboard (3)]
↳ ACPI Virtual Keyboard Device id=21 [slave keyboard (3)]

Attempting to set gesture:

Code:

xsetwacom set 11 Gesture "on"
Property 'Wacom Enable Touch Gesture' does not exist on device.

So not really sure what to do now...

I wasn't aware that X couldn't do multitouch, but the X config file settings look promising.

You are aware that X doesn't support multi-touch events, are you?

As for the "touch = click" issue, did you try and change the repeat-delay settings? (how much time between to touch-events to be seen as separate taps)

I quite like my HP tm2 laptop - I had problems for ages with it getting hot, but after finally working out how to get the vgaswitcheroo to work in debian (mainly it was a case of putting the kernel modesetting variables in different places for both sets of drivers and then actually *loading* the damned drivers!) it runs rather cool now - cooler than windows 7, in fact.

Now I can almost abandon windows for regular use, except when using it as a touchscreen laptop.

Yes, the touchscreen works fine, but it lacks the finesse that the windows setup has. Touching it immediately classes as a tap, so there's no drag-scrolling. It's also not possible to right click by pressing and holding or pressing and right tapping.

I'm assuming there must be a set of variables somewhere in a config file for the X side of the wacom drivers, and possibly some add-on software the make the experience a little more polished?

Oh, and don't suggest going to Ubuntu - I've tried numerous recent versions and just prefer Debian.
