Unity-Compiz not working on Multi-Monitors with Nvidia cards (option composite enable)

Asked by Bohors on 2012-03-24

Have you ever managed to activate the composite option for Multi-Monitors on nvidia cards ?
Unity 2D run without problem on my 3 screens. if I'm not mistaken, there was a bug with the composite option and Xinerama on nvidia cards. Is it solved ?

sudo lshw -C display; lsb_release -a; uname -a; dpkg -l | grep nvidia

Thanks

i can confirm this issue on a 4 monitor setup, nvidia, ubuntu 12.04_64bit.
DE starts up without compositing enabled.
No accellerated graphics available somehow.. even though the drivers installed properly.

xinerama enabled and seperate x-screens.

we'd like to use ubuntu on our multi-monitor workspaces, but this bug makes it a quite lacking experience.

Can you help with this problem?
