This seems to be simliar to the bug I have been following here: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/956071
Largely newer Thinkpads with Intel graphics. I have tested with the xorg "edgers" PPA and still had the issue. I can reproduce the crash by doing successive suspend / wake cycles. Usually crashes (kicks out to lightdm, that is) after 3, but sometimes the 4th wake from suspend. In this case (quick successive suspend / wake attempts by closing the lid), I can see when it crashes because the lenovo "half moon light" remains blinking after the lid is closed (should go solid after suspend achieved). I should note that in this above case when I open the lid I am already back at the lightdm login screen. Other "real life crash times", the machine wakes up fine, but after approximately 30 seconds to a minute (while using the machine) it kicks me out to the lightdm screen (as others report here). The above bug report has a few full backtrace calls after one of the reporters heled us get our machines set up to do full reporting. There may be info there that can help here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/956071 Title: Xorg crashed with SIGSEGV in XIGetDeviceProperty() To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/956071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
