Public bug reported:
If I select "Suspend" from the Power menu, my computer suspends as
expected.
When subsequently pressing the Power button on the front of the computer
to wake it, the computer's hard disks power up but the monitor (and
hence the computer in full) does not.
A press of the hardware Reset button on the computer appears to make the
computer reset, but the computer does not subsequently progress to the
BIOS POST screen--at this time, it hangs/freezes in the same manner as
when first being woken from suspension. It is actually necessary to
hold down the Power button such that the computer is forced to switch
off fully, and then turn it on again.
/var/log/pm-suspend.log (attached) makes reference to the suspend being
performed, but doesn't appear to report anything else after going into
suspension. I don't know what other log files may be relevant, but am
more than happy to provide any that are deemed to be.
