How to make your pen tablet work
Wacom and Aiptek pen tablets in Linux

introductionThe pen and tablet or stylus is an important tool for graphics artists, and once you've used one, you never want to go back to a mouse. The pen is simply far superior. So one would have thought that the Linux development teams would have paid ample attention to this kind of input device, particularly since few brands exist.
Both the Wacom (American) and Aiptek (Taiwan) wands satisfy the requirements of a mouse, and should work immediately as such, which both do, without any drivers. But a mouse gives relative co-ordinates, whereas wands give absolute co-ordinates. One would thus have expected that the Xorg committee, who specified the behaviour of the Xterminal (KVM= keyboard/video/mouse), would have defined basic behaviour of a pen. With that in hand, programmers could have implemented standard drivers. But this was omitted.
So we are now stuck with ad-hoc initiatives, of which the Wacom driver came first. Already since 2001 the first drivers became available, yet six years later, they have not been turned into a standardised package with standardised documentation - a clear example that an organisation like Debian is needed to get finished products out of the door with stringent quality assurance and milestones.
With the Wacom driver in the lead, one would have expected that the Aiptek driver would simply mimic the Wacom behaviour as a de-facto standard, so that at least we would have ended up with one driver, but instead a top-heavy design was started which again, did not produce installable packages.
I have a few gripes with Linux developers in general, and my main frustration is that these gurus serve themselves with the latest versions of module libraries, while also specifying that their work depends on these. In doing so, they force whoever installs their package, to upgrade a host of interdependent libraries, even when this is not strictly required.
So both the Wacom and Aiptek tablet drivers have become a sorry story, a blot on Linux, particularly since there is no doubt that recent versions should work fine. But who compiles the sources into working packages? The good news is that the situation may suddenly change for the better - just have patience. Remember though, that the manufacturers can't and won't help because of Microsoft's bullying.
Note! much ado has been made of tweaking the /etc/X11/xorg.conf file, but after trying all the advice that is scattered over the Net, nothing really worked. In Xandros this file has already been prepared for the Wacom pen, and it may need to be adapted for Aiptek perhaps.
the Wacom tabletThe Wacom tablet is loosely (unenthusiastically) supported by Xandros, and Xandros Networks will tell you that version 0.6.6-7 is available, complete with kernel modules and toolbox. This loads and installs fine, but documentation and driver are out of step, and the xsetwacom tool gives error messages. All the same, it works - sort of.
xsetwacom set stylus clickforce 15 xsetwacom set stylus button3 1 xsetwacom set stylus button2 3Adjusting clickforce is the most important one.
These settings must be done automatically once the Xterminal starts
up, and this is done by including these commands in /etc/X11/xinit/xinitrc
but perhaps because of the error messages, this won't work satisfactorily.

Driver package: xserver-xorg-input-hyperpen_1.1.0-1_i386.deb causes serious dependency problems.
