Ok, so I'm trying to install Vector Linux 6.0 Standard Gold onto 8 Dell Optiplex 5500 (model # may be wrong) computers in my church's computer lab. As far as I know, all have a 2.0ghz P4 processor and 256 megs of ram. They're mainly going to be used for light office applications with (as of right now anyway) no internet access whatsoever. My main concern is whether or not these machines are powerful enough to use xfce. Right now, I've got Vector installed on 3 of them (5 are still without power, of which 3 still need keyboards) and LXDE is working properly on one of them (one of them has no xorg file (strange, but fixable) and the other one seems to have a faulty cd-rom drive). So far, LXDE works well on the computer that will boot to it, but I can't figure out how to change backgrounds.
So, to repeat. LXDE or XFCE on these machines? and Can you change the background on a default LXDE install?
