Well, I am glad that someone is examining the problem! When I attempted to purchase some technical support today, I was told that Red Hat did not support SiS 630 video. I noticed in my /var/log/XFree86.0.log there is only one warning: (WW) SIS(0): Option "<Option Name>" is not used There were no errors. Lots of references to Glcore and libGLcore; nothing with a (WW) nor an (EE). Running 'fc-cache -f -v' does not solve the problem.
