A friend of mine just installed FC3.
Then, she wanted to install xine. Not finding it in yum, she went out to build it from soure. The configure script suggested installing Xfree86, which she did.
Of course, this blew away xorg, and X stopped working.
I got xorg working again by running rpm -i --force xorg-* in the RPMs directory of each of the install CDs.
In particular, X works, up until you log in. Then, no matter which session you've chosen, you get TWM.
How do I get the usual desktop environment back?
