It used to work fine: I would close the lid and Ubuntu would nicely suspend and resume when I opened the lid.
Now I find that it does not. What happens first, I don't know, but on reopening the lid, the computer boots up as if from a cold start. The same thing happens when I run sudo pm-suspend
, so it has nothing to do with the lid settings--it's just that the suspend command seems to simply reboot.
I have been messing with libinput
around the time when it happened, installing and uninstalling it and alternating with the synaptics driver, but I'm unsure if this is related.
