Hi all.....Im a programmer and I use mysql & php at work so I built a PC and put Fedora core 4 on it. My monitor is a Samsung 173v. When I installed Fedora I was using a different monitor and everything seemed ok, but when I brought it in my office and set it up, and started it, everything looks ok until it tried to display the screen after the initial boot up and then my screen goes blank, and I get a floating message, "Video mode not supported". This is at the point where it goes from the screen that says "press i to enter interactive and the last message i see is "STORAGE NETWORK AUDIO DONE"....So I hooked it back up to yet a different (old) monitor and it booted up fine. I know enough to get around in linux a little, but am primarily a programmer......Id appreciate any help. Thank you...

You'll need to edit your X config file and change the default resolution. If the Samsung monitor is connected, boot up as normal and when the screen goes blank, hit "ctrl+alt+keypad plus key". That should cycle you through the configured resolutions. Find one that works. If this doesn't work or none of them work, then hit "ctrl+alt+F1". This will give you a console to login from. Login and type:

The first makes a backup of your X config file. The second opens the config file in the vi editor.

Scroll down to your screen section and locate the modes. First, look at your DefaultDepth. This is the color depth that is being used. Then, locate the Display SubSection that uses that same depth. Look at the modes and determine which is the bad one and which you think is the good one. If only one is bad, the it'll be the one with the highest setting. You can either remove it (useing the delete key) or move it by editing the line and reordering the modes.

To use editing mode in the vi editor, press the Insert key. Do your editing, then press the Esc key. To save the file, type ":w" without the quotes. To exit, type ":q" without the quotes. Reboot and see if this helps.
