I upgraded to 9.10 from Xubuntu 9.04 using the Update Manager. It installed many new packages and removed some packages which is no longer officially supported.

After rebooting, I entered my username and password in the login screen (GUI). The authentication was successful. But then none of the panels, desktop and so on showed up. X seems restarted and it went back to the login screen again.

However, login via command line was possible by pressing ctrl+alt+f2.

I found a file named .xsession-error in my home directory.

In the line: Failed to init the UI: 未知选项 --sm-config-prefix
it is "unrecognized option" in English.

The message of Fatal IO error 104 is "connection reset by peer" in English.
And Fatal IO error 11 is "resources temporarily unavailable"

The attachment is the output of "dpkg --get-selections" in case it may help.

What is wrong with it and how to fix it?
