Hey how is it going you guys?

I have a little poblem here. Just finished installing RedHat 8 on my computer here. Everything throughout the installitation worked fine exepct to the point where it asked what screen resolution I wish to use so, I selelted 1240 by 780... then the computer froze. After rebooting it just dumps me to the command prompt. I don't know what command it need to enter to get the GUI up!?

anyone knows? I hate to run the setup again which took me more than 3hrs.

Thanks for any upcomming help.
