Fedora help on screen resolution

[dylan1234]

I have FC 4 on a Gateway PC with an 17" monitor I tried to change my
screen res from GUI and now when FC boots it turn my monitor off.
I was able to get back to root. Is there a file that I need to config
to get my monitor working again ? Thanks

hi dylan1234,

Welcome to the LinuxForums.

log in as root in command line mode and execute 'system-config-display' command. configure resolution and video driver. if your Monitor is not listed in Monitor's list, select 'Generic' Monitor.

Graphics is configured by /etc/X11/xorg,conf file, you can edit that file manually too but try 'system-config-display' command first.

Hi,

At my root i typed # system-config-display

I got the following:

audit
"
"
couldn't start X server on card 0
counldn't start X server with old config, trying with fresh configuration

audit
"
"
_ cusor stops here.

whats the output of startx command?
if startx throws error too, edit xorg.conf file manually.

nano /etc/X11/xorg.conf

set Video Driver to "vesa"

Section "Device"
	Identifier  "Videocard0"
	Driver      "vesa"
EndSection

in case, it doesn't work, post the Screen and Monitor sections here.

The ' start X ' command turned off the monitor quickly and then it stopped after :

(==) Using configfile: " /etc/X11/xorg.conf"

I used CTRL-Z and ended it.

I did run ' nano /etc/X11/xorg.conf ' and found the following:

Section "Monitor"
identifier "Monitor 0"
vendor name "Montior Vendor"
model name "GWY7658"
display size 330 240
horizSync 30.0 - 70.0
vert refresh 50.0 - 120.0
option "dpms"
end section

Section "Device"
identifier "Videocard 0"
driver "NV"
vendor name "videocard vendor"
boardname "Riva Tntz"
end section

* These are the two sections I found for the monitor. If I change the
driver would I just need to select X for exit and would the settings be saved
and then try to reboot ? When this first happened my GUI screen was half the size of my monitor screen. I went to the tool bar and selected display and choose another setting larger and it re-booted and now it turns off the monitor when booting up.

- Thanks

change "NV" driver to "vesa", save file ( press Ctrl+X, y and Enter key to save file ) and execute 'system-config-display' command. execute 'startx' to check GUI. no need to reboot.

I also have this computer setup as a dual boot for FC4 and Win2000 with Oracle10g installed on both. When I set this up I had help and we had trouble with finding a driver for FC 4 and the monitor GATEWAY2000 CrystalScan 17"
It is an older model monitor and I may be getting a new monitor for this in the future.

It was working good but my Oracle EM interface is very large compared to on the Win2000. Do I need to find the a driver for FC 4 and this monitor so my EM is the normal size ?

-Thanks

do you know correct HorizSync and VertiRefresh rates supported by that Monitor?
Refresh rates make a lot of difference. set correct rates in Monitor Section of xorg.conf file.
"vesa" is a generic driver and it works for all types of Graphics Cards and Monitors.

[dylan1234]

I got the same when running : # system-config-display

audit
"
"
couldn't start X server on card 0
counldn't start X server with old config, trying with fresh configuration

audit
"
"
_ cusor stops here.

Should this run quickly or should I wait ?

[dylan1234]

Ok - I will google for the rates. Do I set them to exacly what the monitor requires ?

-Thanks
