Title:
Cannot wake-up from sleep mode
Status in linux package in Ubuntu:
Incomplete
Bug description:
Since Ubuntu 17.10 (development version) my computer can go to sleep
mode but it cannot wake up. It used to work fine with Ubuntu 17.04
I tried with both Gnome and Unity. The computer correctly goes to
sleep mode. I can hear the power management unit specific click when
it's done.
If I try to wake up the computer (by using the power button, as I used
to do on 17.04), some devices wake up like the keyboard and the mouse,
but the monitor stays off.
