=> do as Chris Picton suggested

Chris Picton said (nearly one year ago :-/) :


I have found the need for many low res screen resolutions for such
thingas as movie playing, xmame, etc.

The method XFdrake uses to enable modes is to enumerate each mode in the
XF86Config file. For example (a newly created file):

Subsection "Display"
    Depth 24
    Modes "1280x960" "1152x864" "1024x768" "800x600" "640x480"
EndSubsection

It would be better (at least under XFree 4, which automatically provides
resoltions from the monitor, if it is capable), to not limit the modes
provided to the user

If I use instead, the following:

Subsection "Display"
    Depth 24
    Virtual 1280 960
EndSubsection

My maximum mode is exactly the same as before, but I have many more low
resolution modes.
