My computer, golubo, is now back online. Special thanks to my friends XXX & XXX for lending me a motherboard for testing, and to SuperGoodDeal for providing me with a new power supply.
Apparently, I'm now a GNOME user… this seems to have snuck while the computer was offline. Presumably, the default window manager changed during an update; right before the power supply blew. I was planning on switching from WindowMaker to GNOME anyway… this is just an incentive.
