I've seen a few answers around here that point to a hostname issue with the xserver.
If you changed your hostname (i.e. your prompt doesn't say john@localhost:> -- if you're a john ofcourse) then you need to add the new hostname to your 127.0.0.1 alias in the /etc/hosts file.
Say you changed your machines name to 'RedHat8Machine1' the line in the hosts file would have to be
127.0.0.1 localhost localhost.localdomain RedHat8Machine1
Hope that helps,
John
