Hi Hunk,

Thanks for the patch.  I have tried it out with Xorg server 1.7.5, but
it doesn't work.

$ xrandr -q | grep connected
default connected 1024x768+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm

So I will use "default".

$ xrandr --output default --rotate left
xrandr: Configure crtc 0 failed

The screen goes black for a moment, then comes back just as before,
i.e., not inverted.  This happens for "left", "right", and "inverted".
 There is no flash for "normal", and it returns immediately.

This is the same with the add/subtract lx_crtc->rotate_mem->size, and
with the add/subtract 1.

This message appears in the X log:

(EE) GEODE(0): Couldn't allocate the shadow memory for rotation
(EE) GEODE(0):  You need 0x300000 bytes, but only 0x0 bytes are available

Is this because I am using Xorg server 1.7.5?  Do you think it would
work with 1.8?  Is there something I'm doing wrong?

I will try 1.8 now.

Thank you for your help!
