My 9400 had the ATI x1400 card and neither suspend nor hibernate work at
all.  Both functions simply result in a blank screen (still powered on)
but a totally unresponsive unit, in all cases I have to power off and
on.

Hasn't really worked reliably since 8.04 LTS, 8.10 was fair but nothing
since.

I will not found any workarounds that fix this yet.

Bug description:
Both suspend and hibernation worked out of the box in both Jaunty and Karmic but fails in Lucid alpha 2. The laptop suspends just fine, but on resume the screen is blank with no backlight at all. There is no kernel panic though, Num lock and Caps lock still lights up their corresponding LEDs
