I have a laptop running Ubuntu 13.10. It was running fine till yesterday when I installed OpenCV 2.4 using Synaptic (if that is of any relevance since there is no other change in configuration). This morning, I powered it on and it comes to the screen asking for login, even showing my background correctly. However, after I login, the screen goes blank. I can see the mouse cursor and it moves when I use the trackpad, but I am unable to do anything else. I am not able to start terminal window or anything else because I do not have any icon. From the login screen, I tried to change to Gnome (instead of Ubuntu default) but still, had no luck. Can someone please help?
There should be a command to go into non-GUI mode but I cannot recall that either.
The output from
lspci | grep VGA is
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primart) (rev 0c)
Looks like it is unable to load
Plugin opengl which must be because of my install of OpenCV.

If it is of any help, I typed the command
glxinfo and got the error:
Xlib: extension "GLX" missing on display ":0". Error: couldn't find RGB GLX visual or fbconfig
