i can't solve a problem with my screen configuration.

I tryed in anher italian forum, but i haven't find a solution.

In my configuration i have an nvidia geforce 480x. I'm trying to use 2 screen, for work, and with ubuntu 11.10 i was using already this configuration, and the only problme was ane error message at the start up, but nothing else.

Now i can't use 2 screen without error. First of all i want eliminate the upper bar from the second screen, but when i try to open the monitor configuration an error appears and sad that the RANDR extension is not present...and when i boot the system ubuntu notify me that he encountered a system error!!!

I've tryed both twinview and separeted screen, but none of them work at well... I can't believe that a thing that work so easy in windows can't work at well also in ubuntu, so please help me!!


PS: This is a link with an image of my 2 screens Consider that for now i don't have anymore the error about the configuration.

You can try to set it in the nvidia-settings program.

For me the nvidia driver is so bad that i removed the nvidia-driver and use nouvau now. Much faster and more stable.. But in your case the card is probably not supported nicely.

I set all the configuration trough the nvidia settings program, this is the problem. Where i can check if my card is supported!? – Roberto Amatista May 9 '12 at 11:18
You can start here: . But your card is very new and i think some features are not supported. In any case, you can try to use it and revert to nvidia-drivers if you do not like the result. – user61664 May 9 '12 at 11:22
I'm trying to download other drivers from nvidia support, my card is a GTX 480...i don't thinki is so new...i mean, at least 2 years! – Roberto Amatista May 9 '12 at 11:38
