I wasn’t sure if anyone had asked this question yet, but here it goes…
I have a Genius G-pen F610 I’d like to use on my desktop running OpenSUSE 12.2. So far everything seems to work well, with one minor exception: the size and shape of my tablet. The Genius G-pen is a 6" x 10" tablet, so it has a 16:9 aspect ratio, but my monitor has a 4:3 aspect ratio running at 1280 x 1024 resolution, so anything I draw with it ends up getting very elongated due to the size of the screen and the tablet being so different.
My question I guess would be this: is there any way at all to limit the area of the screen the tablet can use? Is there a special driver or a .conf file that can be edited to make this possible?
I tried xinput --list in terminal and got this:
⎡ Virtual core pointer id=2 [master pointer (3)]⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ USB Optical Mouse id=8 [slave pointer (2)]
⎜ ↳ WALTOP International Corp. Slim Tablet stylus id=10 [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)]
↳ Power Button id=7 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=9 [slave keyboard (3)]
Assuming the Waltop driver is my tablet, I decided to try xinput list-props “WALTOP International Corp. Slim Tablet stylus” and got this:

Once I can somehow limit the area of the screen this tablet can use, I can start using OpenSUSE exclusively for my work without having to rely on windows anymore. 
Any help or advice I can get with this would be greatly appreciated.lol!
