I am a new user...

[Cassandra]

Hi!   I am a new user to this group and I am a new user to Linux since yesterday. I have Redhat 7.3 and did install it yesterday. I chose to select to install everything and did wait to cinfigure the videocard until after the installation.   I typ: Xconfiguration at the prompt and tries to configure the card but it doesn't work. I have Cirrus Logic GD5422. The monitor is Fujitsu ICL ErgoPro 151p. Before I tried to configure it I tried to type: startx but it says no screens found so I guess it is the videocard?? I do find the card in the configurationprogram though. What I don't know is what to choose when I configure it manually. I don't know how much videomemory...resolution...hz...etc...   Can somebody help me?   Thanks Cassandra
