where did my 2nd screen go?

[Werner Schram]

This is more of a reply to all five of you messages, but I'm not going 
to quote all of them. Summarized: You tried to install the nvidia 190 
driver (from the nvidia site), but now your 2nd monitor isn't recognized 
anymore and it looks like the 185 driver is still loading. Am I correct 
at that?

Yes, it seems that you are still loading the 185 module.

According to this, your module is installed in for the 2.6.31-14 kernel. 
Is this the kernel you are currently running? Because the latest is 
2.6.31-15. Maybe this is related to your problem?

could you inventorize which nvidia modules are currently at your 
machine? Do this by running the following commands in a terminal:

updatedb
locate nvidia.ko

Could you also post which kernel you are running (uname -a)?
