I broke my GUI :-(.

The problem started when I accidentally moved my entire /usr/share folder to a different directory. I moved it back to /usr/, but now when I try and startx, it times out.

Xauth can't find a file. It was something like severauth.4905. After it times out looking for that, it starts timing out looking for some other file. It is looking in the /home/myusername/ directory. I don't understand how moving the /usr/share folder would have done that though.

I tried a whereis on both the files it was looking for with no results.

Any advice?

Listen for other suggestions first, but if you have /home on a separate partition, could you reinstall without much harm?

I don't use slackware, but might it also be possible to fire up some live-CD version of slackware (slax maybe), could you copy its /home/share contents to your hard drive?

Again, maybe others will offer better suggestions

I had a similar problem but never solved it. Ended up installing Ubuntu (which I was planning to do anyway). Have you tried reinstalling x-windows with apt-get?

Maybe its just a typo, but maybe /usr/share is now in /usr/usr/share!

Also, have you tried running the Reconfiguration script for X server?
I believe it is something like xorgcfg or xorgconfig.
This also is a nice command: xorgcfg -textmode
