This morning, I logged into Unity 3D and noticed that everything was really slow and unresponsive. I pressesd ctrl + alt+ F1 to open a terminal and diagnose the problem. It turns out that compiz is constantly using 100% CPU.
I checked the software center for recently installed updates and found out that yesterday some updates for the nvidia driver had been installed. I have installed the nvidia driver from the System Settings -> Additional Drivers menu. I'm using Ubuntu 11.10 64 bit and my videocard is a Nvidia 8800GTS.
I have tried the following to solve the problem:
- Uninstall and reinstall the current driver (I have the 'version current [recommended]' installed)
- Install another driver version. In the Additional Drivers menu some other driver are available
- Install the nvidia driver from a PPA
I was unable to solve the problem. Any ideas?
