Monitor flickering and going black after install of Redhat 9

Greetings to all,

Recently I decided to install the linux OS on my system, alongside winXP. Purchased a second HDD for it, downloaded Redhat 9 and today I installed Redhat. First thing I came across was that the anaconda GUI would not properly start, all I could see was some flickering. Rebooted and started the installation with the parameter "linux resolution=1024x768" as was suggested in boot options. After this, the installation GUI would come up nicely and I completed the installation without problems. Restarted the system, and selected Redhat in GRUB. The text mode part of the boot went fine, but as soon as the GUI kicked in, the monitor flickered again. I tried installing Redhat all over again, since at the end of the installation I was asked to pick my videocard and monitor from a list. The videocard was in the list, my monitor was not. The first time I selected the monitor whick was found during probing (CPQ TFT5015), because my monitor model was not in the list. Since this caused problems, the second time I selected a model which came close to my own model, but same result. Tried to find a linux driver for my monitor, but no dough. I hope someone here can help me out.

System specs:
Pentium IV
512 MB RAM
Asus PB4
Geforce 2 MX400

Compaq TFT5015 (flatpanel)

Sounds good, but where do I setup the default monitor and resolution? redhat-config-xfree86 does not works, since it wants to start xserver, and xserver isn't working.

Did you look at the XF86Config file? Section "Monitor"

as db077, edit XF86Config file and under Monitor section, put the refreshrates appropiates to you monitor and under Screen section put the resolutions. an example would like as:

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Samsung SyncMaster 950in(T)"
DisplaySize 360 270
HorizSync 30.0 - 96.0
VertRefresh 50.0 - 160.0
Option "dpms"

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1920x1440" "1600x1200" "1400x1050" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"

This is only an example, modify it to fit your monitor.
