fedora11 freezes at login screen

[arn_ml]

hello everybody,
yesterday i was trying to configure my apache web server 2.x.x.In the process i changed the permissions of the var folder as..
chown -R arun var
chgrp -R apache var

and i also set the respective execution permission to the subfolders www,cgi-bin etc

Till here no problem faced.Web server configured.

Now when i restarted my system and booted into fedora 11 it gave me the error "Could not update file /var/lib/gdm/.ICEauthority" (after booting).

Then i went to the rescue mode and changed the owner of var and all of its subfolders to root..

chown -R root var

I also found that /var/lib/gdm/.ICEauthority file had no execute permission set for the owner root and group "gdm" .So, i gave the execute permission as well.

Then i booted into fedora 11 again and there was no error this time.But my keyboard and mouse stopped working at the login screen....
In short fedora just freezed at my login screen.

I searched google for similar problems but all were associated with installation problem.As of my case i have been using fedora 11 smoothly for the past 3-4 months.

Also keyboard working properly in single user mode.

Thanks in advance...
