After some updates my gnome-shell theme is broken (looks like old gnome2).

I tried many things:

  • uinstalled alls gnome-shell extensions
  • uninstalled and again installed gnome-shell as well
  • uinstalled gnome-tweak-tool
  • removed ~/.themes directory
  • removed ~/.config/dconf
  • installed lxappearance
  • removed gnome-accessibility-themes and then installed gnome-themes-standard

Nothing helped and right now I'm loosing my mind

Some info:

System Info -> Graphics shows: "Experience Fallback"

gnome-shell --replace
Xlib:  extension "GLX" missing on display ":0".

(gnome-shell:7853): Clutter-CRITICAL **: Unable to initialize Clutter: The OpenGL version could not be determined
Window manager error: Unable to initialize Clutter.

Other command

gnome-shell
Xlib:  extension "GLX" missing on display ":0".

(gnome-shell:7855): Clutter-CRITICAL **: Unable to initialize Clutter: The OpenGL version could not be determined
Window manager error: Unable to initialize Clutter.

Looks like a nasty bug. What video card are you using and which drivers ? –  bodhi.zazen Dec 19 '11 at 1:25
    
I have Intel GMA X3100 in my thinkpad t61. I have default drivers and haven't changed anything. Previously everything was ok any even /etc/lib/nux/unit_support_test -p got possitive results. Right now looks like there is some driver problem. I tried purging and reinstalling xserver-xorg as well –  user657429 Dec 19 '11 at 14:37

It looks like one package installed nvidia drivers even though I only have intel graphics. I removed it and followed the following topic and it finally worked for me

Switch from NVidia to internal Intel HD graphics - OpenGL does not work
