problems with GDM after upgrade from fc4 to fc5
Yesterday I upgraded to fc5 from fc4. Yes, I really like it and it's greater than before in most sides. However a strange problem occurred. I started one game with wine , the system tried to change resolution ( I think ) and it hang up. There was only black screen. I tried to log out back to GDM with ctrl+alt+backspace and again nothing happened. I also tried to open a new terminal with ctrl+alt+F'N' ... the system was down. After reboot all services were starting OK, it again hanged up when it comes to load GDM (only reboot works, by hand). What is interesting to me is that if I enter "Single user mode" first and after that "#init 5" GDM loads and I can load my KDE. If I try go log out, the system again freezes.
I really think that this problem is related to X and GDM. Moreover I think that if default my GDM installation it will be OK. Any ideas what can be done or where exactly the problem could be.
