Re: Generate basic xorg.conf

It fails while X is running because it has to access the video interface to determine what it is, the clock rates it supports, and the resolutions it supports - not to mention what the monitor definitions are. Doing this can cause the video board to reset some internal values or simultaneous access to the control registers will cause really strange errors to occur to the display.

Current X servers do not need, nor should they have, an xorg.conf file. In extreme situations (usually caused by monitor errors) it cannot determine supported resolutions and will choose something basic. In these situations you can override that part of the default by putting sections in /etc/X11/xorg.conf.d.
