GNOME shell crash on multiple monitor setup

I freshly installed Fedora 23 today. My setup is:

  • A laptop with a 1080p screen
  • A external monitor 1080p (hdmi)
  • A external monitor 1024x768 (vga)
  • Intel integrated graphics i5-4210M CPU

The GNOME shell crashes on the following circumstances:

  • Opening settings
  • Opening the videoplayer
  • Opening Steam

What happens exactly is that all screens begin to flicker black and random fractions of my open programs. When I open the terminal (via a shortcut) it stops and all my resolutions are mixed up or a crash occurs. If I do nothing, a crash occurs.

When I have no extra monitors connected to my laptop, the bug does not occur but the GNOME shell hangs for about 3 seconds.

What can I do to stop this from happening?

This is probably driver related, and hard thing to answer because it could be totally hardware dependent. If you tried multiple monitor setup with different hardware then you would know if it is a general issue with GNOME or more specific issue with some of drivers your hardware uses.

Also good move would be to install Fedora 24 which was just released to see if that changes things, or prior to installing it just run it via live USB to see if your hardware works better with Fedora 24 which has newer drivers so maybe these issues have been resolved in the mean time between Fedora 23 and 24 releases.

If you still see same issues then only course of action is to report this issue/bug to Fedora Bugzilla and ask developers what kind of debug logs then need from you to "see" this issue in a way that they understand and can make this issue actionable for them.

Completely other way of handling this issue could be not to use GNOME, you can try out multiple other desktops to see if they work better for you and your multiple monitor setup. Try out KDE, Cinnamon and Mate for start.

Thank you for answering! I think I will consider switching to another DE.
