I blew up my Linux install today.
I wanted to test out a Livejournal client; I figured "Hey, what damage can I do? It's only a Livejournal client!"
Yeah. After attempting to install GTK to get this sucker up and running, I managed to mess up the displays so that it doesn't even boot up anymore with the graphical interface. Looks like I'll have to reinstall again sometime, though that means I'll have to go through getting the wireless working again...
At least I am learning more about Linux, and I'm hoping next time I can get even further before messing up my system.
