So I have been using linux mint for a while now. A few months ago my Gnome shell crashed and I was unable to use the full 3d features and loaded into fallback mode only. From that day (around 2 months ago) I still have only fallback mode (both Gnome and cinnamon). I installed Linux mint maya, and Ubuntu 12.04 both as windows file and complete installation in an external hard drive. and for many times I sitll cannot fix this problem. ps I made sure to download all the drivers for my graphics card. what could the problem be?
I've got crash when using Rhythmbox, switched to amarok and everything is ok now. It may be application (not drivers) problem then.
