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 http://www.obit8.com/Errore.png Consider that for now i don't have anymore the error about the configuration.
