Description of problem: When trying to narrow a different problem, I commented the `Load "dri"' statement from xorg.conf. With that, X would not start. A white band appears on the LCD, gradually growing in brightness. Version-Release number of selected component (if applicable): xorg-x11-drivers-7.0-2 xorg-x11-drv-ati-6.5.7.3-4 xorg-x11-server-Xorg-1.0.99.1-2 kernel-2.6.17-1.2157_FC5 How reproducible: Always, on the given hardware Steps to Reproduce: 1. Comment `Load "dri"' from xorg.conf 2. Start X Actual results: Video is not initialized, system lockup. Expected results: Normal operation (only slower) Additional info: This is Dell Latitude D600, which I got from Havoc. His former desktop group ought to have more of these. 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R250 Lf [FireGL 9000] (rev 02) The driver is "radeon", without the "ati" multiplexor. The problem happens with any kernel which I tried. I encountered the problem with xorg-x11-drv-ati-6.5.8.0-1, which is current for FC-5 at present time. I down-stepped the package. It may have been there for a long time.
Please attach the Xorg.0.log from the failed startup. I suspect X is actually starting and just doing violently bad things to the display.

When I collected the above log, all the symptoms were the same as I described, except that the system DID NOT lock up. So, I logged in over the network, run ps and found that the X process was not present. Then, I collected the log. However, there's nothing in the log telling anything about the crash, it just ends abrubtly. There was no oops or other misbehaviour in the system either. So it looks that kernel is unable to restore the text mode once X had control and crashed. That part may be a kernel problem. But my objective is to have X which does not exit...

Seems working now. xorg-x11-drivers-7.2-4.fc7 kernel-2.6.20-1.2990.fc7
