I use Ubuntu 12.04. My graphics card is Geforce GT540M.
I opened Synaptic Package manager and installed the following:
- nvidia-common
- nvidia-settings-update
- nvidia-common
- nvidia-current
- nvidia-current-updates
The following were installed before(when unity launcher looked normal):
- jockey-common
- psensor
- nvidia-settings
- jockey-gtk
- xserver-xorg-video-nouveau
My intention was to use the right Nvidia drivers. But apparently it didn't rightly install the drivers and now I have Unity 2D running!
sudo lshwin the terminal and post the appropriate part. – Ashu Jul 15 '12 at 15:36
