OK, i made this work by removing kdesktop_lock executable (does this have
any hidden consequences?). Trinity is clearly multi-screens aware, it
maintains a separate panels/desktop configuration for a second screen, and
programs started from a menu invoked from second screen panel start on
a second screen. 

So far i like this way more than multiple monitors on a single screen.
Separate virtual desktops on each monitor are GREAT. Of course no problems
with 0:0 not on a main monitor. The only real drawback (apart from
inability to move windows between monitors) is that you cant have different
chrome or firefox windows on a different monitors without going different
profiles.
