Well,

besides pixels and colors you still have to consider the refresh rate. It might be too high under Linux.

To answer Michael-the Xconfigurator utility did exist in redhat untill redhat 7.3 version.Starting from redhat 8.0 it was removed...

Jazz,
you can try the following to fix your display problem:
run:
X -configure
at the promt.It should give the following output:

Your XF86Config file is /root/XF86Config.new

To test the server, run
'XFree86 -xf86config /root/XF86Config.new'

if it'll work ,just copy the file /root/XF86Config.new to /etc/X11/XF86config

[Mark Grant]

edit /etc/X11/XF86Config

IN there you should find a section for "Monitor". Apart from the "identifier" comment out everything and put in an Option "DPMS"

If your Monitor doesn't support dpms, comment it out again and look for your "Screen" section. There will be a "DefaultDepth" entry (put one in if there isn't) and make it 24. Then in your Subsection "Display" for 24 bits have a "Modes" line of the resolution you used to have. Once this is OK, try for 32 bits instead.

thanks for your continued help on this one guys!

I'll let you know how I get on...

how do i edit the XF86config file?

[Mark Grant]

Hey jazz,

Well, use your favourite text editor, "vi", "emacs" or even "kedit", "gedit" (I am sure that last one must exist) and edit "/etc/X11/XF86Config". You will have to be root and make a copy of the existing XF86Config first.

Hi,

You perhaps vill have to install a management rpm to have a tool to recover your configuration. I recommend the folloging:
redhat-config-xfre86:
redhat-config-xfre86 --reconfig

This command will ignore the existing cfg and will recreate the XF86Config configuration file.

You can also use:
/usr/bin/X11/Xconfigurator --kickstart to reconfigure your display.

Best regards,

Celso

Woho ! Time to get in. Sad not to have seen your thread before ! It's indeed a hard problem but the solution is easy !
You have to force your system to re-autodetect your video configuration.
As everybody stated, go to another console thru ctrl alt F1 or F2... Then, here is the key solution :
redhat-config-xfree86 â reconfig
Your systme will be re-configured. If your system file seems correct for the configurator and still doesn't work, you can try :
mv /etc/X11/XF86Config /etc/X11/XF86badconfig
It'll change config file name. Then run :
redhat-config-xfree86
Having no config file to rely on, the system will build a new one, as during install time.
You'll get your X back !
