I get an error from the terminal when I run the operation "compiz --replace"
GConf Error: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)
(process:2192): GConf-WARNING **: Directory `/apps/compiz' was not being monitored by GConfClient 0xa1f7c20
Could someone explain how to fix this?
