Monitor problems

[jawsnnn]

Hi,

I installed FC6 on my computer, with Windows XP

Configuration:

Intel dual core 1.6 GHz
1 GB RAM
256MB graphics card - nVidia 7100GS
160GB HDD
Intel original motherboard D945GCNL

The problem is that the installation proceeded fine, in graphical mode (though my graphics card was not identified - it just said "video card -nvidia corporation unknown")

But during startup process, just after it says press 'I' to enter interactive startup mode, the monitor turns off and its lights start blinking. I can't figure out whats the problem. PLease help, I'm a complete greenhorn.

After the machine boots, see if you can get a console login (for example, try CTRL-ALT-F2). If you can login this way, login as root and try running the script system-config-display. If that method fails you can work on the problem from the command line. If you aren't familar with linux command line commands, you'll have to ask for futher directions.

How do you run the script system-config-display? I have a similar issue. Installed FC7 and it won't display in the GUI. I'm fairly new to Linux and would really appreciate any assistance.

I'll try that...but to repeat the poster above what to do once you run the script, and how do you run it?

Assuming you have logged into a console (as root) , you type the command and then press the enter key. So you type:
system-config-display
and then press enter.
If the machine can't run that command then the next thing to do is to examine the log file for the xserver (/var/log/Xorg.0.log) and the configuration file for the server (/etc/X11/ xorg.conf). If you search on this forum you can find many messages about xorg.conf files and how people change them. To examine a file without changing it, use the "less" command. For example, type:
less /var/log/Xorg.0.log
and press enter. Then use the up and down arrow keys to read the file and type 'q' to quit.
A typical problem you might find in the log file is a message that says something like "mode 1024x768 rejected" and it might give a reason like "hsync out of range". Then you would need advice about how to edit your xorg.conf file to fix this problem.

Hey thanks for that....I managed to get my system started in text mode by going in the bootloader and changing the runlevel to 3.

From there I ran the startx command and the system runs smoothly.

Thanks for the help, though I still don't know whats the problem. Will post again when I find out. cheers
