I have a working system RH8. Want to replace my CRT monitor with a new LCD. How do I start to change setting to the new one. Log in change setting and log out , then change monitors, re log in? Or use original RH8 CD's at start up? I assume that I have to have the setting correct before logging in, otherwise LCD with be using CRT setting.

New LCD Cornea TFT 17 MP704. Plan on using VESA standards 1280 x 1024 64khx (h) and 60hz (v).

Side Note: Also checked RH package manager and was surprise to see that it shows " X Windows System" as not being installed. I was thinking this was necessary for Grome/RH8 to run. Everything seems to work fine on my system now, except Log Out (get a black screen), so I always use Shut Down.

You might have to change your refresh settings in /etc/X11/XF86Config file, if you have it going to X right away you will want to edit you /etc/inittab file to 3 from 5 till you get X working properly, you might also have to change your screen resolutions to the new size you want. If you are changing your video card in order to use the new monitor that will also have to be changed.

Or if you are not comfortable editing the XF86Config file by hand try running
xf86config or redhat-config-xfree86 which is graphical

Hope this Helps

BTW you might want to backup your current XF86Config file incase you want to use your old screen.

I do not plan on changing the video card. I have installed one other rpm okay using the package manager. So I assume I can install the "X Windows System" packages if it is necessary.

If I make these changes when do they take affect? On the next boot up?

If I hook up the new monitor will if know that I changes monitors and stop and ask me to set it up?

These X packages are installed on my RH8 plus others.

First I would make sure to change my /etc/inittab file to 3, if you don't boot into a console.

Then backup your current XF86Config file cp /etc/X11/XF86Config /etc/X11/XF86Config.old

Then edit your XF86Config file by hand or using the other options I mentioned above. Once this is done then type startx and see if X starts.

If it doesn't work go back and edit the XF86Config file or run one of the two programs above.

If worse comes to worse you can always restore your backuped XF86Config file setup for the old monitor and use the old monitor.

I can't see any problems as long as you have your refresh rates for your new LCD, since I am using LCD on my laptop.

If your extra lucky when you boot into RH and kudzu detects the monitor change it will configure everything for you.

Good Luck, let me know how it goes.

BTW if one setting didn't work and X is screwed up hit CTRL-ALT-Backspace, re-do the settings and try startx again, in Linux no reboot is necessary.

Well, I'm up and running on my new LCD. All that worry over nothing. It was so easy. Done in 5 minutes.

Using old monitor did the following:
RH8:
Main Menu
System Setting
Display
Advanced
Configure
Generic
Laptop Display Panel 1280 x 1024
64.0 khz
60 hz
OK
Note: Setting take affect on next boot up.
Shut down
Shift to new LCD monitor
Boot up again
Success!
Beautiful

THANKS! JayCnrs

I did the back up like you said, luckily didn't have to use it. Learned about the level 3 and 5, didn't use it yet. From everything I've read my "X Window System" has to be working, because the GUI GNOME, KDE is working. Not sure why the RH package manager shows it as not installed. Will re-review that later.
