During my experiments with kernel 3.2.0, the xorg also crashed. I had to disable X11 acceleration for 3.2.0 kernel to work. Same story with kernel 3.5.0. This means that I erred on comment #2 where I claimed that simple reversal to 3.2.0 fixed the problem. Apparently I forgot to mention that somewhere inbetween I disabled X11 acceleration.
For what it worth, I tested the 3.7.0-030700rc2-generic kernel and found that it behaves the same way as the 3.2.0 and 3.5.0 kernels - e.g. there is no difference between them (from the bug's perspective). Before upgrade to ubuntu 12.10, both kernel (3.0.0 I guess) and X11+acceleration worked properly. I will update the bug's title to represent the fact. ** Package changed: linux (Ubuntu) => xserver-xorg-video-sis (Ubuntu) ** Summary changed: - Segfault on SiS 65x/M650/740 card + Segfault on SiS 65x/M650/740 card when acceleration is on -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1072148 Title: Segfault on SiS 65x/M650/740 card when acceleration is on To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-sis/+bug/1072148/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
