Public bug reported:
Due to issues with "waking from suspend", I have modified a few entries in
/etc/systemd/logind.conf to use hybrid-sleep instead of suspend, namely
'HandleSuspendKey=hybrid-sleep', 'HandleLidSwitch=hybrid-sleep' and
'HandleLidSwitchDocked=hybrid-sleep'. On a few occasions now, I have closed my
laptop lid while it is plugged it and when I return to it later, it does not
resume on lifting the lid. The disk spins up and the fan runs as if the laptop
was resuming but I am unable to do anything other than hold the power button
down until it shuts down - much as I had to when I was having problems with
suspend. When I hit the power button again and select the entry for Ubuntu in
grub, the laptop boots to the login screen normally. When I log in, everything
is just as it was when I originally closed the laptop's lid - basically
"resuming" the way I had hoped. I do not believe that this is the intended
behavior as I have had my computer resume from hybrid-sleep without powering it
off in 16.0
4 and in 16.10 (I have not, that I know of, experienced this problem while on
battery power). In case it is relevant, the current values of 'Suspend when
inactive for' and 'When the lid closes' in Settings > Power are "Don't suspend"
(for battery and plugged in) and "Suspend" (for battery and plugged in),
respectively.
I will attach the output from 'cat /proc/version_signature' and 'lspci -vnvn'
but I would like to add that 'sudo lspci -vnvn' sent 'pcilib: sysfs_read_vpd:
read failed: Input/output error' to stderr, which was not redirected to the log
file.
