Changing Monitor


Hi,

I'm have three servers with Redhat 7.2. One is running X and the other two are not. I want to change out my monitor to a new 21 inch job. Can someone take me through a brief tutorial on what files I need to change in order to switch out the monitor?

Thanks!

The actual file that you will change is going to be the /etc/X11/XF86Config (or XF86Config-4). Instead of manually changing all the frequency values and such, I recommend you run `xf86config` or `Xconfigurator`. Xconfigurator is a little more better than xf86config, but tends to auto-detect wrong settings sometimes.

So go ahead and change out the monitor, run Xconfigurator, and then you can boot into X with your new settings.

Good luck

Is there anything that needs to be done to the non-x machines?

Thanks!

Not really, they most likely work with no problem.

Okay, I ran Xconfigurator and though it does autodetect the right graphics and monitor, the choices it gives me for 8, 16, and 24 bit (namely 640x480 and upward) all look like hell and only show half of the horizontal size of the screen. As for fine tuning, is there any suggestions. Again, thanks for answers so far!

Other than the fine-tuning knobs on the monitor itself, I cannot give any other advice. Since you are working with a 21in monitor, the aspect ratio is a little different and I'm not sure if you have to do some advanced tweaking. I suggest seeing if you are running the latest version of X and check out www.xfree86.org and see if they have any advice or documentation on it.

Good luck!!

you can also run /etc/rc.d/init.d/kudzu
or you can run:" setup" from the command line.

You can always adjust your horizontal size later in /etc/X11/XF86Config-4

Also check your monitor manual for the horizontal and vertical frequencies and check them against those stored in your XF86Config file

If they are differren enter the ones supplied in the manual

Hi,
After using Xconfigurator and ending up with a half screen,
check if the line; Virtual "numberxnumber" is in your
XF86Config-4 file. If it's there comment it out, or delete it.
As far as i remember you can force Xconfigurator with
--expert for not using autoprobe. (i am not sure tho, cause
at the moment using XFdrake and that can be forced with
--expert --noauto in mandrake)
And take a look at xvidtune to tweak several settings, be care-
full not to overdo things. (man xvidtune)
Good luck
