GDM errors about ICEauthority

After upgrading my opensolaris installation i had troubles with GDM on start with these messages:

Could not update ICEauthority file /.ICEauthority

There is a problem with the configuration server. (/usr/lib/gconf-sanity-check-2 exited with status 256)

To fix them i did this using an xterm session login:

pfexec usermod -d /var/lib/gdm gdm
pfexec rm /usr/lib/xorg/modules/extensions/GL
pfexec ln -s ../../../../../var/run/opengl/server/ /usr/lib/xorg/modules/extensions/GL
pfexec svcadm restart gdm

It should work! Anyway here is the link to the topic on the Opensolaris forum: http://opensolaris.org/jive/thread.jspa?threadID=120672&tstart=0
