[Openchrome-users] CLE266 screen rotation

[mscdex]

I recently compiled and installed the latest openchrome release (.903 as of this writing). I have an old epia ml6000ea board that has the CLE266 integrated video chipset. Everything seems to work just fine, however I have only had partial success in rotating the display.

If I try to use xrandr with X running, nothing I try does anything or I get an error "invalid parameter attributes." However, if I specify the device option "Rotate" and set it to "CCW" for example in my xorg.conf, the display is in fact rotated but the resolution is not correct. There is a black section at the bottom of the screen with the rotated display above that. If I move my mouse up towards the top of the display (to the right if you're looking at it rotated) then the display slides up (or to the right) as if it is a virtual size/display of some kind. No mixture of settings I've come across has remedied this problem yet.

Is there something I'm doing wrong or is rotation not completely supported for the CLE266 chipset? I have even tried explicitly setting the option "NoAccel" to "True" when setting the rotation open in xorg.conf with the same results as noted above.
