Public bug reported:
Upgraded from feisty to Gutsy
I have an nvidia based twinview system, just got a nice new samsung 24"
monitor (syncmaster 245b, recommended) 1900x1200.
Previously had 2 Neovo F419 1280 x 1024, which works just fine and as I
expect. Thought I would replace the left hand one with the samsung as an
experiment. Started compiz and that works fine, I have windows and a
rotating cube working just fine. Just no window decorations. Does not
matter whether I am using gtk-window-decorator or emerald.
Running either decorator manually --replace has no effect, nor does it
send any errors out.
Note that the config is unusual, 1900x1200, 1280x1024
