[Settings] Does not work disable power off laptop the ACER Aspire ES1-732-C078

Hi !

The laptop does not work power off.

The laptop hangs and I press the power off button on the keyboard.

When you "Leave" the session, and choose Shut Down, does it hang then too, or only when you press the physical button?

I press the "Logout" -> "Shutdown" -> the laptop freezes -> I click the button on the keyboard "Shut Down" to turn off the laptop.
I press the "Logout" -> "Reboot" -> the laptop does "Reboot".
I press the "Reboot" -> and laptop freezes.

I think I need to add something to blacklist.

Sounds like some logout process is hanging. I'd begin by reviewing logs. Also try Logout > Reboot and leave it be. It might just finish after a long, long, LONG wait and leave behind a log trace.

From 13.26 to 14.00 the laptop tried to Shut Down.

Looks like SDDM might be frozen. Try this: Log out of the GUI, then hit CTRL-ALT-F1 and log into the terminal.

Then type:

sudo service sddm stop
sudo reboot now

If sddm dies and the system reboots properly, then the hang is sddm not dying. If sddm won't die from the above command, then sddm is the problem. The log shows "sddm-helper" is crashing whatever that is.

[alexandr-makukhin]

Sddm is not installed.
Lightdm failed.
The reboot works correctly.

I was having the same issue of hangout on startup/shutdown with Ubuntu 14.04 on an Acer E3-111-C9NY, found a solution for it on:
https://bugs.launchpad.net/ubuntu/+s...x/+bug/1341925
Basically, you have to blacklist the modules dw_dmac and dw_dmac_core, you do that by adding to /etc/modprobe.d/blacklist.conf the following lines:
blacklist dw_dmac
blacklist dw_dmac_core
After that, the laptop start/shutdown/suspend works fine.

CTRL-ALT-F2
sudo systemctl stop sddm.service
He froze, as when turning off the laptop.

Does
sudo systemctl poweroff
shut down your computer properly?

The command you used at the CLI is not visible in either of those images.
Did you actually issue the "sudo systemctl poweroff" command in a Konsole to shut down your computer?

[alexandr-makukhin]

Yes. The monitor blinked and showed the text.
