[Bug 911591] Re: gnome-shell crashes when resizing OpenGL window
@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 Desktop Bugs, which is subscribed to gnome-shell in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

@James Please, dont revive a deadly report, its useless and spamming the report with different data. That is not the best way to catch dev attention. As you can see, that report have not got a single dev question or answer; do you mind why ? If you still have that problem, then confirm it still exist on a fresh recent install (not on a system that got many dist-upgrades, and polluted with old borked settings. As you are using a nvidia driver, either follow the #8 link's comment about adding nvidia parameters in such a case, or confirm when using 'nouveau' instead. In both cases, install the dev packages to get a usefull report using ubuntu-bug. ** Changed in: gnome-shell (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Adding journalctl logs for gnome-shell crash. After segfault line, gnome-shell crashes and I'm returned to gdm login screen. Once I login, everything works again until next crash, usually caused by OpenGL window resizing or xrandr resolution changes. ** Attachment added: "gnome-shell-crash.log" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/911591/+attachment/5016779/+files/gnome-shell-crash.log -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Bug seems to be reported also elsewhere: - ArchLinux: https://bbs.archlinux.org/viewtopic.php?id=231158 - RedHat: https://bugzilla.redhat.com/show_bug.cgi?id=1250128 The RHEL bug report mentions that they have Xorg configured without RandR support. I do see a message in my logs that says gdm has RandR disabled for some reason: Nov 30 15:25:53 saturn /usr/lib/gdm3/gdm-x-session[3918]: (--) RandR disabled I'm not sure why gdm wants to run with it disabled. I don't seem to have a /etc/X11/xorg.conf file anymore... it's been quite some time since I've even had to edit Xorg config in recent Ubuntu versions. Seems like all this is managed by gdm-x-session now? ** Bug watch added: Red Hat Bugzilla #1250128 https://bugzilla.redhat.com/show_bug.cgi?id=1250128 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 911591] Re: gnome-shell crashes when resizing OpenGL window
As original reporter stated, it usually appears related to OpenGL window resize events. I have also noted that xrandr display resolution changes can trigger the crash. I see errors in dmesg that mention libmutter: [15040.472843] gnome-shell[32127]: segfault at 8 ip 7f327f29d5d0 sp 7ffeccf94a38 error 4 in libmutter-1.so.0.0.0[7f327f243000+142000] -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
