>From your Xorg.0.log that looks like a GPU freeze - has apport offered to report this freeze for you, because the Intel chips generally have good freeze detection and will attach all sorts of useful information.
If it isn't collecting that, then it would be good if you could boot, adding “drm.debug=0x06” to the kernel command line and then SSH into the machine once X has crashed and run “apport-collect 613628”? If that doesn't work, SSHing in and running “apport-cli --save intel- logs.crash xorg” will produce an intel-logs.crash file which you could attach. If *that* doesn't work, grabbing dmesg and the contents of /sys/kernel/debug/dri/0/ would be good. -- crash when turning off screen with xrandr https://bugs.launchpad.net/bugs/613628 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
