Adding the Stellarium project to this bug. I'll try to add more details here to enable the develops to debug this issue, although I understand as I see nothing in any error logs.
I'm using the latest Stellarium from the release PPA on Ubuntu 15.10 x64 (0.14.2-1ubuntu1~ppa3~ubuntu15.10.1). The system is a Intel Core i3-3240 CPU and I'm using the integrated graphics (HD Graphics 2500 with i915 driver). Similar to the other bug reporters, I get a full X hang. I can return to a terminal to kill X (using Ctrl+Alt+F1) and restore access to my system. There are no error messages in the X.org log file, syslog or dmesg. I have attached the stellarium log after launching stellarium with the -d option. I see no error messages in this either. ** Attachment added: "Stellarium log file" https://bugs.launchpad.net/stellarium/+bug/1437931/+attachment/4575489/+files/log.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1437931 Title: starting stellarium causes system crash To manage notifications about this bug go to: https://bugs.launchpad.net/stellarium/+bug/1437931/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
