I have Lenovo X200 laptop. In 11.04, it suspended & resumed reliably.
For the last week or so, running oneiric, the laptop has not suspended
reliably. Specifically, when I suspend it for the second time, it starts
to suspend – moon LED flashes, screen switches to black, blank terminal
with a single non-flashing cursor – but never completes suspending. I
inevitably end up having to force power-off by holding down the power
button.
I asked on #ubuntu+1, #ubuntu-devel and #ubuntu-uk on how to report this
effectively. The "best" help I got was someone telling me to try from
unity2d to see if it's a compiz bug. I have the same problem under
unity2d. My advisor told me to log it as a linux bug.
