Binary package hint: xorg

Dear developer community,

My freshly installed and fully updated 10.04 alpha 3 works perfectly
fine on my ThinkPad X100e whenever I am on AC power, however, it
immediately freezes entirely whenever on battery and X is running.

What I tried already:

    * tail -f /var/log/syslog: just stops on the freeze, no new line appears, not useful.
    * acpi=off in grub: no change
    * disabled various things on start-up in /etc/rc2.d but no change


Finally, I disabled GDM on start-up and, voila, it worked, no more crashes, but of course also no X anymore. After logging in on the console, the system crashes again on "start gdm".

Thanks, great job guys!!
