The computer is a Dell Inspiron 9100 laptop with a 3.2GHz Intel P4, 1.5Gb of memory and a Radeon Mobility 9800 videocard on a 1680x1050 LCD panel.

X is xorg 6.8.99.5 radeon or ati driver.

	
>Description:
	
  With an xorg.conf using ati or radeon driver, when using gtk based apps, the
system freeze from the user point of view: only a power switch off can be done.
The speed of the internal fans increase (forever loop?).

I have encounter the problem with many gtk based apps: firefox, nautilus, gnumeric... and the gtk buttonbox demo.

I have been able once to freeze the laptop while exporting the display on another computer.

I can provide much more details on request.
>How-To-Repeat:
	Browse the web with firefox or try to open a file.
	Resize the buttonbox gtk demo window.
>Fix:
	Replace "radeon" or "ati" by "vesa" in the xorg.conf file.
