This may be of no value, but it might be a useful data point. I have been seeing what sounds like the same thing on my laptop. When I attempt to exit X, the screen undergoes several changes, ending up with seemingly randomly colored squares that I'd estimate at 8x8 pixels over the left third of my screen and vertical stripes which may be duplicates of one line of my background on the remainder. The display just sits there and I have no way to see any console messages, but the console keyboard is alive and well and I can enter commands (such as 'shutdown -r now') and they work, assuming no typos. If I attempt to shutdown from Gnome, I get the same result except the shutdown completes in about the normal time and the system reboots. One very significant difference from other reports is that I am not running Intel graphics. I have an ATI(AMD) Radeon X300. Seems odd (though not unbelievable) that two drivers would exhibit the same mis-behavior, at least in terms the the symptoms. -- R.
