The screen rotating behavior has changed for me now. It is different at least as of 2:2.6.1-1ubuntu4, but may have changed earlier.
Currently, with UXA on, attempting to rotate gives a very garbled partial rotate screen which takes about 10 seconds to paint. With UXA off, attempting to rotate gives a completely black screen from which one needs to kill the X server to recover. On the other hand, unrotated, non-UXA performance has improved. -- rotating screen degrades performance with intel driver https://bugs.launchpad.net/bugs/214668 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
