Ubuntu – Ubuntu 18.10 – Issue with screen inactivity and lock screen

gnome-shellidlelock-screen

Clean installation of Ubuntu 18.10 beta

I want the screen to turn off after 1 minute of inactivity, but I do not want the system to be locked when it is activated again. So I do :

gsettings set org.gnome.desktop.session idle-delay 60
gsettings set org.gnome.desktop.screensaver lock-enabled false

The screen turns off after 1 minute of inactivity. The problem is that after that when I try to access the system it is stuck at a purple screen similar to the one of the lock screen but with no input form for password. The only way to access the system, is to suspend the system and then resume.

Do you have any view on this?

I was also experiencing this, and found that it was due to a Gnome Shell Extension.

My experience is that logging in initially was fine. Logging out and logging back in was fine, but resuming from a 'lock' status was causing the issue. I simply could not get the 'shade' to swipe up to reveal the password input. No swipes on the trackpad, mouse, or keyboard presses would reveal the input.

Try disabling all extensions and then logging out (not just locking) so that your session is restarted.

After that you can go in and start enabling extensions one at a time, log out, log back in, then lock (super + l). If you can't log in, the last extension you enabled is the culprit and you'll have to either way for an update to be compatible, and it'd be super awesome if you go let the extension developer know on the extensions.gnome.org page.

Ubuntu – How to disable lock screen based on which WIFI network I’m connected to

You can use this shell script. Check this to get the info of your WiFi.

#!/bin/sh

trusted_essid="trusted-wifi-name"

while :
do
  current_essid=$(iwgetid -r)
  if [ "$trusted_essid" = "$current_essid" ]
  then
    gsettings set org.gnome.desktop.lockdown disable-lock-screen true
    echo 1
  else
    gsettings set org.gnome.desktop.lockdown disable-lock-screen false
    echo 2
  fi
  sleep 60
done

Edit this file as root:

sudo gedit /etc/network/interfaces

add under wlan0 (or your Wifi interface, ls /sys/class/net | grep -o "wl[^\t]\+"):

post-up sh /path/to/wifi-smartlock.sh
