Comment 22 for bug 144305

This is still a problem for me in Jaunty.

Additional things I've noted are that gnome does not display a suspend option, and 'lshal' reports that 'power_management.can_suspend' is false (which, I think, explains gnome not offering a suspend option). What seems interesting about this is that other threads have reported that these machines do not support hibernating, an option that gnome does offer, but that they do support sleep/suspend to ram. Manually setting 'power_management.can_suspend' to true and then using gnome's suspend functionality just "flashes" the screen and then presents a logon screen. If I switch to a virtual terminal and run either '/usr/lib/hal/hal-system-power-pmu sleep' or 'pbbcmd sleep' the same thing happens: the screen blanks, but the machine does not go to sleep.
