Ah. I believe this is the problem, or at least very closely related: <http://cgit.freedesktop.org/xorg/xserver/tree/fb/fbseg.c#n693>: if (clip2 != 0 || drawLast) len++;
in combination with these variables: new_x1 = 36 new_x2 = 0 new_y1 = 16 new_y2 = 0 clip2 = 10 len = 37 This incremented len to 37, extending (in reverse) the line below (0, 0), which leads to a segmentation fault. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/416421 Title: [gm45] X crash on X200s with dual monitors (using DisplayPort) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/416421/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
