i use ubuntu 16.10 on laptop (with closed lid) attached docking station , external monitor. after lock (i.e. through ctrl+alt+l) machine, ubuntu suspends after few minutes. how can disable behavior? i aware of power options in system settings. choices follows: maybe problem solved disabling "suspend when lid closed" (as technically, lid closed when device attached docking station). however, prefer keep "suspend when lid closed" option since use laptop without docking station. thanks help! you can try this. open terminal , type: gksu gedit /etc/systemd/logind.conf set these 2 lines this: handlelidswitch=suspend handlelidswitchdocked=ignore save file, reboot , test under 2 environments (docked , undocked). if unacceptable results, change power settings "do nothing" on lid close event have set "suspend" now. shouldn't have reboot test 2 environments again.

in aws ec2, login ubuntu user ssh keypair: ssh ubuntu@hostname -i path_to_the_keypair now, want shift root user try login root user entering $ su root and asks password how enter ssh password. is there way change user using ssh keypair? no. can't authenticate su using keypair. have configured sudo , can "change root user" using sudo -i .
