I tried to get a backtrace according to "Already running programs" for X from https://wiki.ubuntu.com/Backtrace
I started gdb on the first virtual console (Ctrl+Alt+F1). After executing "continue" in gdb, I can still switch between the different consoles, but after typing Ctrl+Alt+F7 to get back to the X session, the system is completely frozen (the virtual console is still visible). Am I doing something wrong? ** Attachment added: "gdb-X.log" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1510998/+attachment/4509199/+files/gdb-X.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1510998 Title: Xorg crashes with segfault on 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1510998/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
