liminal, I believe this should be fixed as soon as possible purely due to the severity of the bug. If I'm using the EXA acceleration architecture and try to run compiz, the machine hard-locks, and I have to force a power- down, potentially damaging the hard-drive and hardware (happens on my laptop and desktop system with Intel graphics). Frankly it seems crazy to keep a patch that causes such a regression.
As for performance, EXA is overall slower with some operations, but faster with others, especially RENDER acceleration. When a certain class of patches is included in mesa/xserver-xorg-core/xserver-xorg-video-* (called aiglx-zero-copy-tfp), compiz & EXA will be much smoother than XAA & compiz. However, these patches may not make it to gutsy in time. The offending patch is to prevent the need for "XaaNoOffscreenPixmaps" in your xorg.conf with XAA, so it's a necessary patch - but it needs to be *debugged* and fixed so that it doesn't conflict with EXA. -- [Fixed] Intel driver (using EXA) crashes system when starting compiz https://bugs.launchpad.net/bugs/126425 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
