This week, I tried to install xubuntu on an old Toshiba Satellite 4200 Pro with 64M of RAM :(
Xubuntu, pronounced as Zooboontoo, is a complete GNU/Linux based operating system with an Ubuntu base. It is lighter on system requirements and tends to be more efficient than Ubuntu with GNOME or KDE, since it uses the Xfce Desktop environment, which makes it ideal for old or low-end machines, thin-client networks, or for those who would like to get more performance out of their hardware.
The documentation clearly state that it needs 128M for install and should run with 64M
Unfortunately the install process freeze after a few minutes, removing the splash screen showed:
Out of memory killed process gzip
Running with Low Graphics start up seems better but freeze again after 5 to 10 min of CRRom/Disk access, but I didn't manage to remove the splash screen when starting this way so I have no clue what so ever :(
So for the moment XUbuntu 0 - Toshiba 1
