penalvch, thank you for your help. I don't want to risk a BIOS update for now, so I cannot tell you if the bug is somehow BIOS-related.
Instead, I have decided to try an update of my graphics drivers using this repo: ppa:oibaf/graphics-drivers This "fixes" the crash problem. So, while it may still be true, that this bug is somehow BIOS-related, the fact that I am not experiencing any crashes since I've updated the graphics drivers suggests that there probably is something wrong with the graphics drivers that Ubuntu 15.10 uses by default. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1511704 Title: Xorg crash (probably on window resize) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1511704/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
