Turns out I can more or less reliably reproduce a crash by frantically moving my pen along the tablet for about a minute or two. That allowed me to attach gdb and get a backtrace (attached).
It seems that I get a different backtrace at different times. For simplicity, I will assume it is all related to the same bug. So I will post here. It is important to say that I downgraded to libutouch- grail1=1.0.20-0ubuntu4 because that's the version that has debugging symbols in ddebs.ubuntu.com. ** Attachment added: "backtrace xorg" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/764700/+attachment/2167694/+files/backtrace%20xorg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/764700 Title: Xorg crashed with SIGABRT in utouch_frame_sync() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/764700/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
