It is reproducible. No idea why the intel driver symbols don't show up, but addr2line shows me: 0x380cc = xf86-video-intel-2.17.0/uxa/uxa-unaccel.c:24 = uxa_check_poly_segment() 0x2f1ec = xf86-video-intel-2.17.0/uxa/uxa-accel.c:624 = uxa_poly_segment() -- 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
