Bug Description
Binary package hint: lxsession
After fresh install of Lubuntu 11.10 alpha 1 on Acer Travelmate 240, after booting, the CPU usage is 100%. The fan rotates at moderate speed, accordingly.
Killing the "/usr/bin/lxsession -s Lubuntu -e LXDE" process in htop makes the CPU usage drop near zero. (However, this either kills the desktop session, or only resets the user settings -- none of which is acceptable.)
This bug was hard to determine, as htop shows 0.0% CPU usage at the line of the "/usr/bin/lxsession (...)" process (!).
EDIT: I made a mistake reporting the bug. It is in _gnome-

I can confirm this behaviour, using Lubuntu in a VM when killing lxsession CPU usage drops down to usual levels and logs the user out of Lubuntu. Upon logging back in lxsession resumes using 100% CPU.
I have also marked bug 796843 lxtask shows 100% CPU usage regardless of actual usage as a duplicate.
