Created attachment 332098 [details] Xorg.0.log (startx without xorg.conf) Description of problem: Fatal server error if runlevel 3 startx without xorg.conf. Gfxcard is Matrox G400 (rev 04). CRT display has dysfunctional DDC. Version-Release number of selected component (if applicable): xorg-x11-drv-mga-1.4.9-1.fc11.i386 How reproducible: Easy Steps to Reproduce: 1.ensure /etc/X11/xorg.conf does not exist 2.runlevel 3 3.startx Actual results: Signal 11 server abort Expected results: X just works Additional info: I don't use Fedora much since bug 430836, but I tried to follow up to bug 448945 on another machine and found this. With the xorg.conf file I created by editing the result of system-config-display last October, X always runs without a startup crash. If I try to create a new xorg.conf with system-config-display, I get a crash similar to that starting with no xorg.conf.
