I recently upgraded to 11.10 on my Lenovo ThinkPad T520, and I'm not able to load Unity 3D (I'm not selecting 2D at login menu either).

me@mycomp:~$ echo $DESKTOP_SESSION

I ran the unity support test below as well.

me@mycomp:~$ /usr/lib/nux/unity_support_test -p
Xlib:  extension "GLX" missing on display ":0.0".
Xlib:  extension "GLX" missing on display ":0.0".
Xlib:  extension "GLX" missing on display ":0.0".
Error: unable to create the OpenGL context

And it looks like I only have one graphics card:

me@mycomp:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

Also, Ubuntu lists nothing under the "Additional Drivers" window.

Any help would be extremely appreciated as I'm somewhat of a noob. Thanks!

Edit 1:

Here is the output of lshw -C display

me@mycomp:~$ sudo lshw -C display

If it has an eg. Intel HD 3000 chipset or an integrated graphics chipset, maybe this PPA can be of help: (to be used with care).

Take a look on the xorg-edgers PPA, add it sudo add-apt-repository ppa:xorg-edgers/drivers-only (this is the relatively safe one) and do an sudo apt-get update && sudo apt-get upgrade, maybe it can already update your Intel xorg driver.

Else you can try the unsafe one (you'll find it on the PPA Launchpad link i mentioned above).

Remember using the edgers PPA can break your graphics.

If you have any issues - you should use ppa-purge to remove the PPA.
