Ubuntu: Unity 3d shows only wallpaper where as unity 2D works fine [duplicate]

Unity doesn't load, no Launcher, no Dash appears

I just upgraded from ubuntu 11.10 to 12.04. When I log in into Unity 3D and Gnome 3 I only get a wallpaper for few seconds and then the screen goes blank with mouse pointer showing. I can easily log in to Unity 2D and Gnome Classic (no effects).

I have Nvidia GeForce 7025 / nForce 630a/integrated/SSE2/3DNOW! Graphic card. I checked my card compatibility using /usr/lib/nux/unity_support_test -p and came out with following result:

jeevan@jeevan-System-Product-Name:~$ /usr/lib/nux/unity_support_test -p   OpenGL vendor string:   NVIDIA Corporation  OpenGL renderer string: GeForce 7025 / nForce 630a/integrated/SSE2/3DNOW!  OpenGL version string:  2.1.2 NVIDIA 295.40    Not software rendered:    yes  Not blacklisted:          yes  GLX fbconfig:             yes  GLX texture from pixmap:  yes  GL npot or rect textures: yes  GL vertex program:        yes  GL fragment program:      yes  GL vertex buffer object:  yes  GL framebuffer object:    yes  GL version is 1.4+:       yes    Unity 3D supported:       yes  

After lot of reading and going through several post and also trying different solutions to it I am still not able to get Unity 3D working. I think the problem is with the Nvidia Graphic Driver 295.40 which is crashing Compiz. I tried to roll back to Nvidia 295.33 but it doesn't allow me to do so as it keeps asking to install from root. I cannot find anyway to login as root. I badly need help. I somehow want to get UNITY 3D running.

Any advice would be appreciated.


I found a workaround to my problem. The problem was with the Nvidia Driver current version (295.40). I had to rollback to the previous version and find out if I can login to Unity 3D. I downloaded the older version of Nvidia Driver (295.33) to Desktop.

I restarted and logged into recovery mode. I selected the 'root' option and logged in as root. I installed the older Nvidia Driver (295.33) using following commandline

cd Desktop

I followed the onscreen instruction and installed the driver. After installing I restarted the computer and this time I able to log into Unity 3D. :)


First try to login as guest/new user ... In my case (final 12.04) Unity-3D worked then. So the reason may rather be somewhere in the profiles than in the system/graphics ...
