* Knowns:
Laptop Compaq 6910p, graphic ATI Radeon. Dual OS: XP and CentOS5_X86_64 (based on RedHat).

** Problem:
runlevel 5 does not work! Error produced: "Failed to start the x server...".

*** Actions:
1- I checked /etc/X11/xorg.conf. Under "Device", the "Driver" is "vesa". So, one may expext that "vesa" would work normally with a wide range of graphic cards!, but you see that on mine, it DOESN'T!

2- I also tried command "sudo dpkg-reconfigure xserver-xorg". But, it cannot be understood by CentOS

**** General Help:
Plz send me whatever you think may be helpful to resolve this problem. (It is my laptop and I have root privilege)

You should be able to find the correct driver for you card at:

But when you go to "Linuxx86_64 -> Mobility Radeon", there is no item for "Mobility Radeonx2300", which is my graphic chip!

There isn't one under windows x86_64 either. What driver do you use there?

Oh!

I downloaded and installed this:
https://a248.e.akamai.net/f/674/9206...x86.x86_64.run

It worked! ‘startx’ worked and started the graphical mode; BUT when I switched to graphical mode, my laptop went to shut-down after some minutes, due to reaching to "critical temperature".
It tells.
“ACPI critical trip point critical temperature reached (127C)....”
I think there should be a mismatch between the driver and my hardware! Am I right?

No, it sounds more like your fan isn't spinning or the air is being blocked. Laptops are quick to overheat as there are a lot of components packed into a small space. It may just be that the heat caused by the graphics chip is adding a bit more heat that your laptop isn't dissipating properly. If there is any dust in the fans, this will also cause problems.
