What happens after you go back to normal (no) rotation? That is broken for me per http://lists.x.org/archives/xorg-driver-geode/2010-August/000995.html Though we are looking into that already right now, maybe you'd like to come to our IRC again ;) Regards, Mart ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Hope you can report anything you think incorrect or abnormal after using that new driver. For NoAccel segfault, I am not sure if you have tried Mart's patch in the below link: https://bugs.freedesktop.org/attachment.cgi?id=35326 I have given a try and it can nicely solve this bug. It is caused by the zero pointer use. Could you give a try? I think Mart know more about that. Mart, Can you make this issue more clear for Bernie? I can't reproduce the issue with no display until VT switch anymore, so clearly I was mistaken or it's been solved by a different commit meanwhile, or it just doesn't happen all that often and the idea of crash being better than confusing picture for most people doesn't hold anymore. So I've pushed this trivial segfault fix to GIT now, to be part of 2.11.9. I don't suggest using NoAccel though, as it loses XVideo and many other non-acceleration (read non-deceleration) related things too.

The most outstanding rendering bug has been fixed. And some performance patch has been applied. I tested the driver on the XO-1 and couldn't spot any rendering bug neither in Sugar nor in Gnome, with full acceleration enabled and no quirks needed in xorg.conf. However, a long-standing bug is still there: setting Option NoAccel 1 makes the driver segfault during startup. Thank you very much for taking the time to do this neat work, Frank!
