Hi,

I just installed Ubuntu 10.04 LT 64 bit on my Sandy bridge PC with dual monitors, and I have a problem with having a desktop that stretches on both monitors. Currently, the same desktop is duplicated on both monitors. When I go to System->Preference->Monitors, only 1 unknown display is shown, even after I click on the "Detect monitors" button.

Also, I believe I'm missing some drivers, as my keyboard/mouse input is severely lagging. The cursor frame rate is abysmal, and I can't type fast without losing random characters.

I'm very new to Ubuntu, never had these problems with Mandriva which I've been using.

How do I fix these problem?

Thanks!

OK I was able to get the graphics drivers installed and multi-monitor to work in native resolution. However, my keyboard and mouse are still lagging. Any idea why?
