I am almost certain it is, but I haven't a clue what the magic spell
would be.

I'd imagine deep in the bowels of xorg.conf, is away of telling it that
the display is bent.

Mmm. After a few minutes probing, it looks like there is a 'Displaysize'
directive in Xorg.conf that takes two parameters - the X and Y pixels
per inch.

Edit (or create) /etc/X11/xorg.conf and put in this


Section "Monitor"
     Identifier  "Touchscreen"
     VendorName  "Wombatronic Industries"
     ModelName   "Gargleblaster 8000"
     HorizSync   30 - 50
     VertRefresh 60
     DisplaySize  650 406
EndSection

and play around with the numbers if it makes a difference. Obviously you
will have top reboot the x server between changes


If that doesn't work, there is a program called xrandr that can be used
to interrogate and set parameters

But the poster there ended up having to use a startup script to invoke
it., because he never found a way to make the changes permanent.

I am now off firmly outside my sphere of competence, so I will sign off.

Good luck.
