The traditional way to hint that you want to be fullscreen is to unmap
your window, request that it become the size of the screen, and remap
it. Opera does this, but it doesn't work, for some reason. MPlayer and
Firefox also do it, but successfully. Opera also throws a curveball and
add Motif WM hints to hide the border and titlebar, which is
nonstandard, but irrelevant (wmii supports them, but only in the -test

The new way is to specify an EWMH hint, but wmii does not support them
yet. It will soon, but it needs to have fairly complete support because,
once you advertise that you're an EWMH compliant WM, apps change their

There's no kind of conflict, and there's no winner, wmii just doesn't
understand Opera's hints properly.

It should work. I'm not quite sure why it doesn't, but the code related
to fullscreen mode will be overhauled soon, and the EWMH hints, at
least, are concrete enough that such problems shouldn't occur once it's

consider themselves lucky to get any programs at all and
