Problem w/monitor settings...
 
I can't find the answer anywhere. I have a *very old* but very good, 20" Radius Intellicolor 20 display. I use a KVM switch to move between a Windows 2K Server, an XP Pro box, and what *used* to be my RH 7.1 Server, but I've now upgraded to 9.0.

Here's my problem. Windows recognizes the monitor as a 'generic' one, and then allows me to go up to 1920xiforget display with millions of colors, at 60 Hertz. Previously I only used the 640x480 configuration for my RH 7.1 gui. The video card is not the same as the one in my W2K server (the Win VCard is nVidia w/32MB, and the Linux is a Diamond w/32MB of RAM. Both were purchased at the same time and cost about the same). I selected a 'Generic 1280x1024 display monitor at 60H, since that is what is working fine on my W2K server.

I can get the 1280x1024 on the Linux box. However, the screen blinks whenever I move the mouse or type on the keyboard on the Linux box now. And there's a nasty little horiz green line on the top left of my monitor. It obviously doesn't like the settings I gave it. Unfortunately, I wasn't willing to live with the lowly capabilities that RH 9 gives a 'Generic Monitor, which is SVGA basically...especially when I *know* this monitor can at least triple that. It identified the video card fine, but stupid me, I didn't write the specifics down for it. Does anyone have any recommendations for what to do to fix this? What file(s) are used for the monitor config? And how can I go about testing various configurations like I can in windows (which hey, I hate, but I work on what my clients ask me too... :( ).

While fairly familiar with linux programming (as far as apache, tomcat, jboss, and java), I'm not the world's best RH systems gu. Ask me to set up apache, tomcat, databases, etc, and I'm fine, but not with hardware attached...and I don't know much about monitor configuration info at all. In fact, I don't even know what file(s) is used as the monitor.config or whatever file, and where it's located.

Could someone help me out here, by pointing me in the right direction? Any help would be greatly appreciated!

Thanks

I think that Red Hat were still using XFree86 for Red Hat 9 so the config file is /etc/X11/XF86Config . Before you start fiddling make a backup copy of the original and rename it a bit XF86Configo will do. That way, if it all goes fubar and you find yourself back at the command prompt you can at least get back to where you started with
cp /etc/X11/XF86Configo /etc/X11/XF86Config
You can open the file in a text editor and alter the values of things. man XF86Config might give you some pointers as might this page http://www.xfree86.org/4.3.0/XF86Config.5.html#sect8
