[Discuss] excessive memory usage in Ubuntu

[Tom Luo]

Hi, Dan,

I did replace the startxfce4 command with
"xfce4-session-manager".
However, I see this screen after I login in. Please see the following
screenshot:

I tired many key combinations. The screen stays the same.
Do you know why?

I also tried LXDE. This works and the memory usage is not too bad.

Thanks,

Tom
