I am running Statler2 xfce and yesterday noticed a marked slowdown in my samsung nc10 netbook performance; with all other applications closed htop revealed the following process eating up cpu .
command:/usr/bin/x :0 -audit 0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7
Previously cpu idled at about 10%. The user is root unlike all the other processes:
Other than doing my usual apt-get upgrade, I have recently installed some third-party software for two dfferent types of internet keys (dongles).

That seems to be the X window server or the login manager gdm. what happens if you log out and back in, or if you kill and restart X or when you reboot?
I have found a temporary fix by removing GDM and also turning off Conky in the startup script. (Conky was doing some strange flickering during this period). Cpu usage has now returned to its normal 2-3% idle rate.
My netbook is even lighter now without GDM. After login, password and startx then the full desktop environment is up and running.
