Rotation with Radeon HD 7700

[Joseph Ward]

I'm new to the list, so I apologize if this has been dealt with previously; I couldn't find anything directly through Google.

I've installed Xorg on my freebsd (10.1-RELEASE-p23) system which has dual Radeon HD 7700 cards in it and 4 monitors.  Everything works well (so far) except that I can't get the monitors to rotate.  In the logs I see the following:


[    50.431] (II) RADEON(0): Front buffer size: 5120K
[    50.431] (II) RADEON(0): VRAM usage limit set to 932043K
[    50.431] (==) RADEON(0): Backing store disabled

[    50.432] (--) RandR disabled

...

[  3110.587] (EE) RADEON(0): Rotation requires acceleration!

I believe this means that due to the hardware acceleration not functioning on the HD 7700 series yet (based on what I found at https://wiki.freebsd.org/Graphics), I'm not able to get screen rotation.  Am I correct?  Is this just something I have to wait for future development, or is there a workaround people are aware of?

Thank you in advance for any help,
