GNOME can work well in VMWare but cannot work in real machine

[Lingfeng Xiong]

hi there,
I found a strange thing. As I described, my GNOME cannot work with
these error messages:
gnome-session[69785]: WARNING: Unable to determine session: Unable to lookup ses
sion information for process '69785'
** (gnome-panel:69812): WARNING **: Could not ask session manager if shut down i
s available: Did not receive a reply. Possible causes include: the remote applic
ation did not send a reply, the message bus security policy blocked the reply, t
he reply timeout expired, or the network connection was broken.


And gnome-panel has a very very slow responding. And also, the driver
cannot be mounted without any error message. The thread about this
problem with more information is here:

I has performed a test, and found that GNOME can work well in my
VMWare!! But in my real machine, no matter how many times I
reinstalled my system, it cannot work.
Could you help me? thx!!
