I had a similar situation, this old desktop has an Intel Celeron (1Ghz), and 512Mb RAM. Ubuntu 8 did not have the wifi-card support i needed, Ubuntu 11-12 did not have the old video card support i needed (actually i think Xorg didn't). Any ubuntu installation would hang right at the end with a "dconf" error. After 9 different flavors of linux, and 12 or so attempts, I finally got a Ubuntu 10.04 Alternative Install to work. The Ubuntu desktop ran very slowly, so I tryed xfce, lxde, and a few others. Again, I finally found what I needed in not just the lxde desktop, but the "lubuntu-desktop" package. The performance was much better, and going against what everyone says about these old machines ("Don't bother trying to upgrade an old machine, just buy a new one..") <-I've read this on ALOT of boards. I spent about $40 with shipping and handling, ordering a new "old" video card (Radeon 7000) to get the graphics processing OFF of the CPU, and onto a GPU of its own, plus 2 sticks of 512Mb RAM (giving me the 1Gb i was looking for). I am very happy with my setup now, I never wanted this computer to run a newer OS, I just wanted it to run. And Ubuntu 10.04 with Lubuntu's Desktop, plus the 2 cheap upgrades I did on my hardware, gave this old PC new life. It was donated to me by someone who thought it had died for good, on the first boot it barely ran the Windows XP that came with it (probably because of the abuse it received from the previous owner), but now I can do everything I want to do with it.
