FastX, Gnome 3: Oh no! Something has gone wrong.


When trying to display a gnome 3 desktop. Gnome displays the following error:

Oh no! Something has gone wrong.
A problem has occurred and the system can’t recover. All extensions have been disabled as a precaution.

This error is typically prompted when trying to bring up a gnome 3 desktop and the host has a NVIDA video card. The problem is FastX’s X display is not compatible with the proprietary NVIDA drivers.


VirtualGL installation is required in order to render gnome 3 correctly.

VirtualGL is an open source toolkit that gives any Unix or Linux remote display software the ability to run OpenGL applications with full 3D hardware acceleration.
