@dino99 Happy to open a new bug report on this, as it still appears to be an issue in latest Ubuntu 17.10. Usually when reporting bugs, I opt to prefer adding information to an existing bug report that I have high confidence describes the problem I am seeing. I believe this helps to reduce creating many duplicates and to focus community effort on resolving the main underlying problem rather than bug report management overhead from many duplicates or "me too" comments with no helpful debug info. If this is not preferred on this project, or for some reason doesn't fit the developer bug triage process here, that's fine. I'm happy to add information upstream or in another LaunchPad bug.
Back to this problem: As it is a segfault reported in upstream gnome-shell which has something to do with OpenGL + resize behavior, I don't believe borked settings are the issue, nothing I've seen yet points towards that, although it'd be nice if the problem could be resolved by a config change instead of code change. This system never had any gnome-shell installed because Unity was there instead. Therefore, no pre-existing gnome-shell configuration can be hanging around. I've posted to upstream bug, but some info was here. To clarify: I do not have an Nvidia optimus nor do I use noveau, but use older nvidia-340 binary drivers. This is the nvidia recommended set of drivers for my card. Another comment in the upstream report mentions the issue may not have as much to do with Nvidia as it does with Xrandr fast video mode changes. I have confirmed this behavior in my own testing, and have a reproduction test case that works pretty reliably for me: Reproduction Command: # Use output and modes that are valid for you... xrandr --output HDMI-0 --mode 1920x1080 ; xrandr --output HDMI-0 --mode 1920x1080 ; xrandr --output HDMI-0 --mode 800x600 ; xrandr --output HDMI-0 --mode 1920x1080 I've tested this a couple times and it looks like I am able to trigger the crash just with fast xrandr commands. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/911591 Title: gnome-shell crashes when resizing OpenGL window To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/911591/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
