I have a nvidia graphics card, and Unity 3D will not load. When I log into a 3D session, I see my wallpaper. I am able to right click. How can I fix this?
I had exactly the same problem. What I had to eventually do is to log out of my account by using Ctrl-Alt-Del, choose Unity 2D then log in again. I tried with different hardware drivers and different user interfaces, but this is the only one that works.
The support for my GeForce 6100 nForce 405 (as the system detects it) has degraded each of the last two releases. With each of the past two releases my computer was unuseable at all until I fixed the video support. WarZone 2100 worked find before 11.10, then it got slower. With 12.04 it is so slow (it takes a full minute for the title screen to come up) that it is impractical to play. At this rate, my graphics card won't be supported at all with 12.10.
Compiz seems to be crashing, causing the whole UI to fail.
- Create a folder using the right click menu.
- Double click the folder.
- Browse to Filesystem -> /usr/bin and open a terminal (I used xterm)
- sudo apt-get install unity-2d
- logout (ctrl-alt-del)
- select unity 2d to log back in
Did it work some time i.e. before upgrading to 12.04? If so, you might probably want to look at Missing launcher after 12.04 upgrade.
I am having the same problem, nothing I have tried seems to be working either. I think it is a bug in the video card driver. We will have to wait for a new driver in order to be able to use 3d. Gnome 3d also does not work. From the login screen I can select unity 2d or gnome 2d and that seems to work fine, although I really like Gnome 3d. Frustrating. I may downgrade back to 11.10 if this is not fixed soon.
I had the same problem. Back then I had solved problem by rolling back to NIVIDIA version 295.33 (current ver 295.40) It worked for me until I did a system update. I lost my graphical interface after updating. Hope this solution might help you.
