With what OS and desktop this is? Have you installed all the updates to that OS version? The warnings in your gnome session output don't indicate an issue with graphics stack, but issue in your system setup: ** (unity-settings-daemon:5087): WARNING **: Name taken or bus went away - shutting down ...

Exiting. gnome-session[5057]: WARNING: Application 'gnome-settings-daemon.desktop' killed by signal 2 Based on above output: - bluetooth doesn't work - pulseaudio setup is broken - cairo version is incompatible with your desktop - upstart environment variable is missing so something doesn't get started - things are run as root although they shouldn't - problem with gnome-settings First two probably aren't critical, Cairo issue could. You need a version of Cairo which ABI matches what rest of your desktop expects.
Using command "apt-get autoremove gnome-shell" to uninstall gnome-shell,after it,install gnome-shell,then it can works well.
