You may have a corrupt xorg.conf file. Boot into runlevel 3, cd into /etc/X11. Create an xorg.conf backup by doing mv xorg.conf xorg.conf.backup. Doing this will essentially remove xorg.conf and create a backup in the process.

Now, try startx. If it still fails to work, try startx -- :0 or startx -- :1.

If that works, try to reconstitute your xorg.conf file by invoking system-config-display --reconfig from the command line.

You must use the spaces correctly if you want to specify the screen number.

startx --:0 == bad syntax
startx --:1 == bad syntax

startx -- :0 == good syntax
startx -- :1 == good syntax

Not adding the space after -- is a common mistake.

Just using "system-config-display" will not work in your case. That is why you use the option --reconfig afterwards to reconstitute your xorg.conf file.

system-config-display --reconfig

Yes

first ,Thank you replied my post

I do the command as you wish
system-config-display --reconfig

Could you try disabling the onboard card and using the other? Removing one of two cards on a power pc got me through an install for SuSE.

Here is a part of the xorg.conf manpage. Please note the part about busid:

Code:

DEVICE SECTION
The config file may have multiple Device sections. There must be at least one, for the video card being used.

Device sections have the following format:

Section "Device"
Identifier "name"
Driver "driver"
entries
...
EndSection

The Identifier and Driver entries are required in all Device sections. All other entries are optional.

The Identifier entry specifies the unique name for this graphics device. The Driver entry specifies the name of the driver to
use for this graphics device. When using the loadable server, the driver module "driver" will be loaded for each active Device
section. A Device section is considered active if it is referenced by an active Screen section.

Device sections recognise some driver-independent entries and Options, which are described here. Not all drivers make use of
these driver-independent entries, and many of those that do don't require them to be specified because the information is
auto-detected. See the individual graphics driver manual pages for further information about this, and for a description of
the device-specific options. Note that most of the Options listed here (but not the other entries) may be specified in the
Screen section instead of here in the Device section.

BusID "bus-id"
This specifies the bus location of the graphics card. For PCI/AGP cards, the bus-id string has the form
PCI:bus:device:function (e.g., “PCI:1:0:0” might be appropriate for an AGP card). This field is usually optional in
single-head configurations when using the primary graphics card. In multi-head configurations, or when using a sec‐
ondary graphics card in a single-head configuration, this entry is mandatory. Its main purpose is to make an unambigu‐
ous connection between the device section and the hardware it is representing. This information can usually be found by
running the Xorg server with the -scanpci command line option.

If you have more than one card, you need to have busid entries in the Device section for each card. They may need different video drivers as well.

If you can, disable the onboard card in bios and try to configure X using the second card. That would be a starting point. If you can get X working on one card, then save a backup of your xorg.conf file. The device section of that card will be what you want and you can work on the Device entry for the second card.
