Comment 6 for bug 399451

In chatting with upstream we've found a workaround and also identified it as not an X bug but rather a metacity bug that compiz is not working around properly.

<agd5f> asac: accoridng to google others fixed that problem by disabling metacity compositer
 gconftool-2 --type bool --set /apps/metacity/general/compositing_manager false
<asac> rock & roll ;) thanks guys
<otaylor> bryce: metacity bug, actually.
<Sarvatt> watch out for this bug if you're calling something with --replace on karmic with metacity the default WM asac: https://bugs.edge.launchpad.net/ubuntu/+source/metacity/+bug/389686
<otaylor> bryce: when it's asked to unmanage the screen it sets the selection owner of the compositor selection to None with a timestamp of CurrentTime, which is newer than the timestamp that compiz is trying to use to replace the window manager and compositing manager selections
<bryce> otaylor, wild, ok thanks.
<otaylor> See section 2.3.1 of the icccm for the specific recommendation that to give up ownership of a selectio you should use the timestamp you used to acquire it
