failed to initialize core devices

I have setup RHEL release 5.8 on my computer that I am turning into a Server. I have set up Trixbox, but i would like to also set up some other features for networking and for this I would like to get into X Windows. However every time I do I get "failed to initialise core devices".

OR

X wont start: Failed to initialize core devices.

I am getting an xorg "failed to initialize core devices" error when trying to startx 

after installing ATI drivers and configuring the card with "anti-config".

Have a look below error snap:-

Solution:-

Edit xorg.conf


[root@sujeet~]# vi /etc/X11/xorg.conf

if u have other server with same Linux OS than match both file & if any thing missing than change it.

Original xorg.conf file contained :

[root@sujeet]# cat /etc/X11/xorg.conf

# Xorg configuration created by pyxf86config

Copy full file contained and past on your error OS platform.
Save it after that restart your OS.

I hope your issue got resolved.
