Yellow Dog Linux 4.0, a Linux distribution for PowerPC-based computers, has been released. I tried Yellow Dog a while back and it installed and ran nicely on my Pismo G3 Powerbook. One of the things that would have gotten me to consider moving to it would have been dual-head support, which means in the Linux world support for multiple monitors, something I am pretty much addicted to when it is available. This new version offers dual-head support for ATI PowerBooks and Power Macs along with a whole bunch of other cool stuff for running Linux on Apple hardware.
