If you are *not* compiling Myth up yourself, then the "separate modes for
playback and UI" mode is not available.  You need to enable xrandr in
settings.pro, when you compile myth.  Xrandr defaults to disabled, since it
is unclear which distributions include it.

Xrandr does not work well with all window managers.  For example, forget
about using it with ratpoison.  It works pretty well with KDE, WindowMaker
and Window Manger Improved.  I personally use Window Manager Improved:


It is a *very* lean window manager which can be used complete without a
mouse.  It is a little funky to learn how to use, however.

When using xrandr, make sure the *first* show you watch after starting up
X/Myth invokes the highest resolution desired.  After that everything works
quite well.  If the first show you watch invokes a lower resolution, when
you do need a higher resolution, it will sometimes mask off part of the
screen.  I occationally think I have found a solution to this problem, but
then it happens again...oh well.
