Comment 5 for bug 209207

I get this also. I've checked the value in that through gconf-editor against a good compiz and it's the same. I did not do a fresh install, but an update and a couple days later X crashed with a gconf error. Unfortunately I did not record what that was.

Now all my old compiz settings are gone, and everything in ccsm is greyed out and unable to be changed. However, when I run "gksu ccsm" all the old settings come back and I am able to change settings. The issue then is that the changes aren't reflected in the system.

I've tried purging and reinstalling compiz, emerald, gconf-backend, and ccsm. I've also tried renaming .gconf, .compiz, and .emerald to something like ".gconf_old" and the problem remains.

Here is the error that shows when running ccsm:

GConf backend: There is an unsupported value at path /apps/compiz/plugins/scale/allscreens/options/initiate_edge. Settings from this path won't be read. Try to remove that value so that operation can continue properly.
