Description of problem: Gnome shell, when using proprietary drivers (tested with version 367.27) crashes after few minutes on desktop with following error: org.gnome.Shell.desktop[1376]: (gnome-shell:1376): Cogl-ERROR **: Failed to create an OpenGL framebuffer object Simple workaround is to switch back to tty with X and the desktop loads again with all your windows intact. Bug is already fixed upstream and patch is available, but was merged too late to make it into 3.20.2. Version-Release number of selected component (if applicable): 3.20.2 How reproducible: Always reproducible Steps to Reproduce: 1. Install gnome 2. Install proprietary nvidia drivers 3. Reboot the system, login and wait Additional info: Patch is available upstream and was merged week after 3.20.2 was released: https://bugzilla.gnome.org/show_bug.cgi?id=764898
