i'm relatively new to Linux, i used it a lot in the past but i have been dumbed down with my recent use of windows. when i run fedora it seems to lock up every time i try to change a system setting. i have read that it might be my graphics card or some hardware issue, but i don't believe this to be true because it is the same on all of my computers. i just re-burned my live CD and will try a full re-install. is there anyone that can maybe point me in the right direction? any help is much appreciated. -update- re-install worked perfectly...so far.
