Compiz cube problems

[a_b_b_]

I am using Ubuntu 10.04. Initially Compiz cube used to run well. However after running the update manager Compiz has stopped running. I tried running it through terminal but this is the message i get:

Xlib: extension "GLX" missing on display ":0.0".
compiz (core) - Fatal: Root visual is not a GL visual
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

Launching fallback window manager


Any help guys?

Also running compiz-check has the following output

Distribution: Ubuntu 10.04
Desktop environment: GNOME
Graphics chip: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Driver in use: intel
Rendering method: None

Checking if it's possible to run Compiz on your system... [SKIP]

Checking for hardware/setup problems... [SKIP]

At least one check had to be skipped:
Error: No rendering method in use (AIGLX, Xgl or Nvidia)

[Forlong]

Did you manage to solve this?
If not, please post the ouput of

dpkg -l | grep "nvidia\|fglrx"

Miraculously the problem resolved itself somehow! :D
I think it was primarily related to some update because the problem started after i completed an update.
Anyway i was trying out the effects using 'Visual effects' and chose 'Extra'. Ubuntu then searched for new drivers (something that hadn't happened previously) and just like that everything was back to normal!
