SDL 256x224 Fullscreen not stretched

[crazylady000]

I am using an old version of Linux (Mandrake 7.1) and have had the following problem for a long time and just found the answer.

Pasting from SDL FAQ at:
http://www.libsdl.org/faq.php?action=li ... egory=3#34



Q: When I specify SDL_FULLSCREEN in X11, the screen goes black and my window is centered in the middle, instead of covering the whole screen!
A: X needs to be able to switch to the desired resolution. For this to work, your monitor must support the resolution, and you need to have the resolution listed in your X server configuration.

The following example is taken from my config for XFree86 4.0.1, but 3.3.x is similiar. Note that if your monitor isn't capable of using these video modes, the X server will drop these modes from the list of available video modes.
Example:

Section "Screen"
Identifier "Screen 1"
Device "3dfx"
Monitor "Samsung LCD"
DefaultDepth 16

Subsection "Display"
Depth 8
Modes "1280x1024" "1024x768" "800x600" "640x480" "320x240"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
EndSection

Note the different entries for 8 & 16 bit screendepth. I.e. the 320x240 resolution is *not* available when X is started with 16bit depth (the default).

To test these entries, restart X after you modified XF86Config and press ctrl-alt-plus and ctrl-alt-minus to cycle through the resolutions.
