I have a problem about my laptop that doesn't suspend when i close lid. First the story.
I bought a new Acer e3-112. It camed with win8.1 and i upgraded it to win10. Then i shrinked the hdd and installed Ubuntu 14.04.3 LTS 64 bit. Without using Gnone, i installed i3 tile manager. Everything was working. Then one day i opened Gnome and i upgraded with apt-get update && apt-get upgrade
Then left bottom of screen started to blink after every start of pc for 1 minute. When i close the lid pc isn't suspending. I read and try
Laptop does not suspend when lid is closed
and realized that /proc/acpi/button/lid/*/state
is alwasy open
. pm-suspend
command working well but i think acpi doesn't realize that lid closed.
What can i do for this?
