rehat-config-xfree86 -- reconfig i getting followig output
"*ddcprobe returned bogus values:
ID: None
Name: None
HorizSync: None
Vertsync: None

Couldn't start X server, trying with a fresh configutation"

I will appreciate if any body can help me in sorting out this problem

Thanks in Advance

Re: Redhat 9 could not start X server

If the graphics card is not supported, this could be very tough.

In this circumstance, your best bet might be RH Es 3 workstation or Fedora Core.

If you hardware is suppored it will be there.

Steven,
I think it is identifying the graphics card, because while installation it said Video card "ATI Rage 128 Mobility detected" for monitor it said unknown monitor. and also installation went fine in the graphical mode

Re: Redhat 9 could not start X server

Maybe you should try to use the good old way : xf86config... But I don't know if it's always included on a RH9.

It's a text based interface that let you choose everything (no probe)

Hope it helps,

Fred

Re: Redhat 9 could not start X server

Hilal,

If I run redhat-config-xfree86 I also see:
"*ddcprobe returned bogus values:
ID: None
Name: None
HorizSync: None
Vertsync: None

Next a graphical configuration screen is opened.

Your error message "Couldn't start X server, trying with a fresh configutation" indicates there is a problem with the configuration file (This must be /etc/X11/XF86Config.)
Check the Monitor Device and Screen section.
I would suggest removing the higher resolutions from your Screen section.

Do you see a graphical configuration screen at all when starting redhat-config-xf86?

Re: Redhat 9 could not start X server

Hi,

cycle through your alternate consoles (). One of those will show you the errors the XServer is really thowing up.

Alternatively locate your X error log and take a look in there (look in /var/log for XFree86.0.log or /var/log/gdm/:0.log).

Depending on whether or not you are using gdm or xdm, if its gdm you could try running /etc/X11/gdm/XKeepsCrashing

Re: Redhat 9 could not start X server

Hilal,

try:
startx >& /tmp/startx.out
and tell us what you find in the file /tmp/startx.out.
I assume the command will end within a minute because you don't see a graphical screen.

Also check /var/log/XFree86.0.log for error messages.

JP.

P.S. You may also want to use Google on 'Dell C800 startx RedHat'

Re: Redhat 9 could not start X server

hello linux experts...

I have the same problem with my Dell C600 laptop... tried the command "startx >& /tmp/startx.out"... things went black and then the CLI came back

I am a Linux newbie and not having the GUI is pretty frustrating for making progress...

help!!!

mike

PS card (detected by installer and able to use graphics during install) is the same: ATI Rage 128 Mobility...

Re: Redhat 9 could not start X server

Take a look at some of the examples on the two following pages:

http://tuxmobil.org/dell.html
http://www.linux-on-laptops.com/dell.html

In particular, I bet you could grab the XF86Config file from

http://www.psych.nmsu.edu/~jkroger/linux/dualboot.htm

and use it without modification.

Re: Redhat 9 could not start X server

To fix an X problem, you better switch to a different runlevel - 3 (no GUI enabled). It's hard to work on X issues while your system runs at runlevel 5 (GUI enabled). Please do the following if you can, and it fixes X problems most of the time:

# init 3 (switch to runlevel 3)
# redhat-config-xfree86 --noui (re-generate xfree86 config file with default values for a generic multi-sync monitor and video card)
