Description David 2003-06-27 00:00:29 EDT
Description of problem:
 I can't use a resolution beyond 640x800 without 1-overloading my monitor (one 
of them got fried) 2-Without it my monitor turning of (my flat screen)
 I got it work under 640x800 on my Compaq 5017m Flat screen
 if i used anything beyond that the monitor says output out of range and shuts 
 I got it to work under 640x800 with my Digital PCXBV-KA but beyond 640x800 it 
squeals, this monitor ended getting overload and stopped working.
 How can I get it to work in a resuluton beyond 640x800( I cant see the enough 
of the app windows to use them, everything is to big) 
What monitor would could I use for 1024x768 or so resolution, I also need to 
know how to change the X resolution from the command promt because I cant get 
back into the linux GUI, i know how to start it, it is that the resolution it 
is at 1024x800 or so turns off or overloads the monitors i have.

Version-Release number of selected component (if applicable):
Linux 9.0

How reproducible:

Steps to Reproduce:
1. Install linux
2. Increase the resolution
Actual results:
 It varies based on the monitor and the resolution.
Expected results:
 Monitor will eather have mulitple images, ghost images, squeals may get be 

Additional info:
Computer is running a Micro-ATX MSI MainBoard. I can run Linux just fine in 
640x800 but beyond that I can't

You can try the 'lowres' option when you boot anaconda, like:

linux lowres
Comment 2 David 2003-06-27 14:15:09 EDT
I can install it under lowres but I cant run Linux above that, I "need" the 
larger screen size so I can use the software on Linux. Every program ends up 
desplaying out of bounds of the screen.
Comment 3 Michael Fulbright 2003-06-27 16:37:07 EDT
Assigning to redhat-config-xfree86 which handles post-install X configuration.
Comment 4 David 2003-06-27 20:02:04 EDT
But how, i tried accessing that program from the command prompt but it runs but 
what command lines do i used
I just tried all these monitors and none will work beyond the lowres at install 
or post install for linux 9.0

Compaq:CV735: Mod# C040554
HP:ULTRA VGA 1280: Mod# D2807A
HP:HP MX75: Mod# P1499A
These all work at the resolution 600x400 but above that they will not, i need 
to get this machine working, its very critical.
Comment 5 Brent Fox 2003-10-16 16:38:40 EDT
I'm having a hard time understanding exactly what you're trying to say.

Try this:  

1) hook up the Compaq 5017m Flat screen
2) as root, run '/usr/sbin/ddcprobe'.  What does the output say?
3) Delete /etc/X11/XF86Config file
4) Run 'redhat-config-xfree86'.  Does the program even come up?
5) If it comes up, select "Generic LCD Panel 1024x768" and then select 1024x768
and then restart XFree86.  Does that work?

Closing due to lack of information.
