help configuring new monitor

A newbie question. I just replaced a monitor on my RH9 box from a Dell CRT
to a Samsung LCD (model 193v). When the system boots up the monitor goes
blank, as if not getting a signal. I understand that the x-windows is not
configured properly for the new display. How do I change it?

Thanks for any help. Please, keep in mind I am very new to this, so if at
all possible, be specific.

Do you see the text display before X starts?

if you do:

ctrl-alt-F1
Log in as root
telinit 3
run redhat-config-display
telinit 5

if not:

fubar

Ok, I see the text display before X. It starts with the Grub menu with Red
Hat being the only option. Once I select that the system proceeds to load
modules. Tried pressing ctrl-alt-F1 with no effect. Once X starts to load
the screen goes blank.

Is there any way to fix this? Is there a way to reinstall and have it
redetect the hardware without loosing all the current settings and files I
already have in the HD?

TIA.

When the Grub splash screen is displayed press the 'e' key. Highlight the
line that begins with something like 'kernel /vmlinuz' and press the 'e'
key again. At the end of the line add a space followed by the number three
(3), press the 'Enter' key then the 'b' key.

Log on as root and type; redhat-config-xfree86

When done test it by typing; startx

If you have your GUI interface then your done, log out of the GUI session
and type 'init 5' when the log on screen is displayed press the three key
combo of Ctrl+Alt+F1 and log off. Press the three key combo of Ctrl+Alt+F7
and log on as you normally do, your done.

Still no joy. Can't get the GUI.

First as root make a copy of the existing /etc/X11/XF86Config file;

cp /etc/X11/XF86Config /etc/Xll/XF86Config.hold

Then try manually edit the /etc/X11/XF86Config file;

http://www.redhat.com/docs/manuals/...figuration.html

And/or try using the available switches; redhat-config-xfree86 --help

Thanks Lenard,

I kind of figured out the switches on my own (with your tip). Still no luck
though. Went through every resolution in the 24 & 16 bit modes. X still
does not show up. Will have to try it with 8 bit.

Perhaps you or some one else can answer a question for me:

With my old Dell monitor X would only work with 1024x768 mode. No other
resolution would show up.
With the new Samsung it is yet to work.
Both monitors were detected by the system for what they are.

Why is it that Linux does not support resolution switching? I have never
had a problem like that under Windows. If it is me and I am doing something
wrong, I'd be grateful for a lesson.

Sorry, but I can't answer this, you didn't specify the Dell monitor model
and you did not supply the video card make and model information. It might
be the Dell monitor/video card combination could only support the one
resolution with the version Linux and Xfree86 you used or are using.

It's also hard to help with the Samsung LCD (model 193v) monitor without
knowing the video card information. You could try using the Generic LCD
Display (LCD Panel 1280 X 1024) resolution choice. According to Samsung's
web site the 193v has a 1280 x 1024 active native resolution with a
scanning frequency range of 30-81 kHz horizontal and 56-75 Hz vertical.

Or you could try editing your original /etc/X11/XF86Config file Monitor
and Screen sections to something like;

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "LCD Panel 1280x1024"
HorizSync 31.5 - 78.5
VertRefresh 40.0 - 70.0
Option "dpms"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection

Linux does support resolution switching well, both my laptop and desktop
systems change resolutions when I want them to(very rarely). I have had
more problems under Windows with hardware (expect for video mostly) then
Linux. Windows chooses address's and IRQ's that sometimes causes conflicts
and problems that can't be easily resolved.

One thing I forgot to mention earlier is once you made the copy of your
original /etc/X11/XF86Config file you should have deleted it. That way
redhat-config-xfree86 would not attempt to use the file as a base even
when using the --reconfig switch.

Well, tried everything you suggested. No luck. However; did get it to work
at 640x480x8bit. No other combination worked. Must be the S3 ProSavage
KM133 16mb video card that came with the computer (onboard video. That's
what you get for $100. LOL). Too bad I don't have a spare card to test out
this theory. Not a big deal though, as this is strictly a serve box.

Thanks again for all your help.

I didn't notice you mention which version of Linux you're trying this with,
but that's the only thing that Fedora Core 1 would run my S3 Savage 4
chipset video card at. Most of the time it wouldn't display options for
other modes, and they were always ignored if I picked them when they were
available.

Fedora Core 2 managed to run my video card fine, though. But I see too
many problems with Fedora to want to keep it. There's a few quirks that
are annoying (like a broken chrooted bind, broken add applications GUI),
but the thing that puts me off the most is the deliberate short life span.
I don't want to be re-installing that often. I've had other systems that
have had a particular OS installation on them for several years, and not
*needed* anything done to them. I wish they'd leave an OS alone and
concentrate their ill-conceived twiddling to non-essential applications.

Not one that I've used, so I'll have to bow out of helping with it. I've
only used Red Hat 7.1 - 9.0 and Fedora.

Going off-topic in a wild way, where's this recent trend of using "my bad"
as a comment come from? The correct way to say something like that in
English was "my mistake". The "my bad" thing that's recently come to play
sounds like someone who don't understand the language, either due to young
age or being foreign. This isn't meant to be a personal attack, I see it
being said in lots of places, but only recently.

LOL! I picked it up during my years in the Army. Which proves what you've
said: "Young age or being foreign". (not speaking of myself) One tries to
communicate to the lowest common denominator. And we did not get a whole
bunch of rocket scientist. Mostly young kids off the street, practicing the
Ebonics to the outmost of their ability...
