Steve, Sorry for not reporting before, but I changed back to Hardy and disabled Compiz in the end of January. This for general stability reasons, Hardy performs more solid on my T61, and I can't risk interruptions on my work computer. I think that vouchy's comment above is relevant to this problem as well as a number of others. My feeling is that it is the combination of the hw, the exa acceleration system, the intel driver that is in the core of the problem, just from scanning related posts. Use of Compiz seems to accelerate the problem. But I don't have any more hard facts, and since I changed back as described above I haven't had any more lockups.
So its fair for you to handle this bug as you see fit, since I can't contribute more. -- X lock-up when logging in from screensaver - crash in intelSwapBuffers()/ intelCopyBuffers() https://bugs.launchpad.net/bugs/275809 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
