Hi, all
To repeatedly cycle test, I have written a shell-script to test the rotate.
Now it can properly rotate in Xserver 1.8 (Need add my gamma correction patch).
Because I have some confuse on memorysize, so I need some time to research
and consider whether this approach is correct. I can not explain too specific.
But it can solve the urgent rotate issue in temporary.
Any other latest update, I will inform.
Please see below change:

Welcome everyone test the code.
I suggest you use:
Rotate left: xrandr --output OUTPUT --rotate left
Rotate right: xrandr --output OUTPUT --rotate right
Rotate inverted: xrandr --output OUTPUT --rotate inverted
Rotate normal: xrandr --output OUTPUT --rotate normal
where OUTPUT would be replaced by one of the outputs shown when you run
`xrandr' without any options. You can use "xrandr -q" to know your OUTPUT name.
BTW: The Xrandr Guide:
http://www.thinkwiki.org/wiki/Xorg_RandR_1.2#Note_for_Ubuntu_Gutsy_users
The `-o' options is a RandR 1.0/1.1 command and may exercise a
different driver code path from the RandR 1.2 `--rotate' option. RandR
1.2 introduced per-output rotation which wasn't available in earlier
versions. Consequently, `xrandr -o' is equivalent to rotating the entire
desktop (composed of all the outputs) rather than just a specific
output. Depending on the Geode driver's support for multiple outputs and
which outputs are connected, using `xrandr -o' could confuse the driver.
Thanks,
Hunk Cui
