All of the things you tried (especially "sax -r" and deleting xorg.conf) were good ideas, and, typically, any *one* of the things you tried should probably have worked. You're definitely on the right track!
Look at your Xorg.0.log file, try to identify the "first" error, and cut/paste it here.
Thanx in advance .. PSM
You might try to create a "dummy user" and log in as that user. Perhaps the real problem is in your local user configuration, and not the global X settings.
