I upgraded to 12.04 and had problems with unity.

So this is what I did >>

1) Ctrl+Alt+F1

sudo apt-get install compizconfig-settings-manager

Export DISPLAY=:0


2) Ctrl+Alt+F7

3) Enabled unityplugin

4) Ctrl+Alt+F1

unity --replace

it worked with a couple of error messages

now I have to put in start up application

export DISPLAY=:0
unity --replace

NVIDIA software recognizes my monitor but Ubuntu sees it as laptop. Something isn't right. Can someone point out what info I need to put here for people to help. I have been upgrading this from 8 ish so have altered lots especially when compiz fusion first came out.

Also if I run recovery session and type unity --replace it starts and runs fine.

Try this in terminal:

sudo apt-get install mesa-utils

makes no change to the unity --replace still brings up errors and for some reason on startup applications it works but if I do it in session it crashes unity with errors. – sh2515 May 7 '12 at 19:14
