I have a HP15 r007TX laptop with Debian 8 (Jessie) installed.
Whenever I close the lid and then reopen, the laptop stops working. It get's stuck showing a blank screen. From there nothing happens and I have to hard reboot it.
I even changed the setting to do nothing when laptop lid is closed and still have the issue.
wmctrl -m
gaveGnome Shell
as the window manager..
