To determine your video card:

Open "System → Administration → Display", then the "Hardware" tab. This 
shows your video card. Additionally, the "Configure" button shows your video 
driver. The video card may be occasionally listed as "unknown video card", 
even though you obviously have a working video driver. And even if the video 
card is listed, it is likely to be a generic name. Run the "lspci -v" 
command in your terminal window. The resulting output will include your 
detailed video card hardware info.

Your ability to use dual monitors depends on the combination of your video 
card and your video driver. In the best possible case, you can get it 
working directly through "System → Administration → Display"'s "Dual Head" 
tab, then finish the set up in "System → Preferences → Display". In the 
worst possible case, you will need to manually install non-free video card 
drivers in order to get dual-head support.
