Re: Rotation and calibration

[Rodrigo Vivi]

Hi,

Actually don't apply that patch directly because it is for xomap.

The only part that may be useful for you is this: (against kinput.c)

diff -ruN xorg-server-1.3.99.0~git20070321/hw/kdrive/src/kinput.c

However, take a look to kinput.c from xorg main stream to see if there
is something better there...
This patch is a little bit old...

[Ryan Gallagher]

Thanks Rodrigo, which file am I supposed to apply this patch against?

Kindest Regards,
Ryan Gallagher.

Maybe there is a bug in your xserver which should be handling it 
transparently using a tranformCordinates matrix.


Please take a look to this patch:

mainly considering the hw/kdrive/src/kinput.c changes...

I did it some time ago to fix the rotation on Mamona/Maemo. I hope it 
helps.

You shouldn't experience this.

Maybe there is a bug in your xserver which should be handling it
transparently using a tranformCordinates matrix.

Please take a look to this patch:
