CentOS Desktop not working on Dell 2950

Hi..

I am installing Centos 5.8 for a required project.

I downloaded two DVDs and installed the software on a Dell PowerEdge 2950.
The install appears to have worked.

The system reboots and starts the OS, but then I see the following message in the screen:

The current input timing is not supported by the monitor display. Please change your input timing to 168x1050x60Hz or any other monitor setting.

How do I reset the timing so the CentOS desktop is displayed.

I tried the monitor setting buttons on the display but there are no options.

thanks

Either boot up in runlevel 3 until you resolve your X configuration issues or try adding the 'nomodeset' boot option. You might also remove the 'rhgb' boot option.

ok,

thanks,

I am not well-versed in linux,,

but,,

On the terminal, I entered:
Cntrl + Alt + F1

The screen shows..

Enabling /etc/fstab swaps
INIT: version 2.86 reloading

How would I add "nomodeset'?

thanks

Read http://wiki.centos.org/TipsAndTricks/ResetRootPassword
Now, instead of adding '1' add 'nomodeset'.

To make it permanent you need to edit /boot/grub/grub.conf.

Appending 'nomodeset' to the kernel line worked.

The OS booted and now I am continuing the config.

Strange issue as to why this happened.

Is it corrected in a later version?

thanks
