on the Toshiba, I've installed a backported kernel so that the Wifi card
works, and I couldn't install the nVidia driver "the Debian way"
(http://wiki.debian.org/NvidiaGraphicsDrivers#Why_use_a_Debian-specific_method.3F)
with this kernel, so I've installed the proprietary nVidia driver.

Prior to installing the proprietary driver I tried the Debian "nvidia" 
driver
and the contrast buttons didn't work either.

I haven't tried "nouveau" yet, though. Have to give it a go.
