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

I have Xubuntu 11.10. Today i installed ubuntu-desktop package to install Unity graphical environment. Unity 2d is working fine but 3d is not.

When i log in, I can hear the Ubuntu login sound and then the wallpaper loads for few seconds and then a black screen is shown. I could see still my mouse pointer though. Any ideas?

  • Welcome to AskUbuntu.com. Can you please give us more information about your graphics card and which drivers you are using? Add that to the question, it will be useful when trying to troubleshoot your issue. – Bruno Pereira Jan 03 '12 at 13:10

    On Ask Ubuntu, instead of writing [SOLVED] in the title of the question, it is better to leave the title so, to upvote the best answer and to mark it as the right one. That's a green check mark. – Agmenor Jan 23 '12 at 18:55

You can take a look at the Ubuntu official page about Unity and its requirements:

https://wiki.ubuntu.com/DemystifyingUnityGraphicsHardwareRequirements

You can try the following command to see if your video card and its driver support Unity 3D:

/usr/lib/nux/unity_support_test -p

  • Thanks. I've resolved it myself. I went to CCSM(while in UNity 2d) and 'enabled' Unity plugin. After that I logged out and log into Unity 3d. This time it worked! :-) – subeh.sharma Jan 03 '12 at 17:07
  • But another problem has arose, I use dual-monitors so I need to disconnect the 2nd monitor before starting Unity and then connect it back otherwise Unity will not load and i get stuck on some blank screen. :-( – subeh.sharma Jan 05 '12 at 11:39
