Stop logging into Xwindows as root. instead, login as yourself, open a terminal, and run this:
su - It will ask for root password. if you give it correctly, you now have a shell open as root. in that shell, run this: chown chris. /dev/sg0 (this assumes that 'chris' is your login.) Note the '.' after chris. This changes the owner and group. Now exit the root shell: exit and exit the 'chris' shell if you don't need it any more. exit However, all of this is a stop-gap for actually fixing the problem. Your system should be capable of managing these permissions automatically.
