Avoid if possible. Outputs to X11 (uses shared memory extension), with no
hardware acceleration at all. Supports (MMX/3DNow/SSE accelerated, but
still slow) software scaling, use the options <tt class="option">-fs -zoom</tt>.
Most cards have hardware scaling support, use the <tt class="option">-vo xv</tt>
output for them, or <tt class="option">-vo xmga</tt> for Matrox cards.
</p><p>
The problem is that most cards' driver doesn't support hardware
acceleration on the second head/TV. In those cases, you see green/blue
colored window instead of the movie. This is where this driver comes in
handy, but you need powerful CPU to use software scaling. Don't use the SDL
driver's software output+scaler, it has worse image quality!
</p><p>
Software scaling is very slow, you better try changing video modes instead.
It's very simple. See the <a class="link" href="dga.html#dga-modelines" title="RESOLUTION SWITCHING">DGA section's
modelines</a>, and insert them into your <tt class="filename">XF86Config</tt>.
</p><div class="itemizedlist"><ul type="disc" compact><li><p>
If you have XFree86 4.x.x: use the <tt class="option">-vm</tt> option. It will
change to a resolution your movie fits in. If it doesn't:
</p></li><li><p>
With XFree86 3.x.x: you have to cycle through available resolutions
with the
<span class="keycap"><b>Ctrl</b></span>+<span class="keycap"><b>Alt</b></span>+<span class="keycap"><b>Keypad +</b></span>
and
<span class="keycap"><b>Ctrl</b></span>+<span class="keycap"><b>Alt</b></span>+<span class="keycap"><b>Keypad -</b></span>
keys.
</p></li></ul></div><p>
</p><p>
If you can't find the modes you inserted, browse XFree86's output. Some
drivers can't use low pixelclocks that are needed for low resolution
video modes.
