I want the lightdm-webkit-greeter to be mine lockscreen, do you know how to change it? I found a way how to add Xscreensaver screensavers to mate-screensaver or even change background, but no word on how to change lockscreen completely.

EDIT: Just to make it clear: I use lightdm-webkit-greeter for login and it works, but when I close the lid, the mate-screensaver-command -l is executed - which I want to change it to lightdm-webkit-greeter aswell using dm-tool lock.

    Well, I don't know if it's a correct way, but yes, I sort of figured this out. I Disabled the MATE's lockscreen in screensaver settings and added light-locker --lock-on-suspend --late-locking --lock-after-screensaver=30 startup command. May 8, 2015 at 9:42

If you want lightdm you just have to install it: sudo apt-get install lightdm. During the install, you'll be asked to select your default display manager. Select lightdm.

If lightdm is already installed, run sudo dpkg-reconfigure lightdm.

  • Well the lightdm was pre-installed and I even managed to get lightd-webkit-greeter to work at system start. So do I have to reinstall lightdm to get the lockscreen changing dialogue? Apr 19, 2015 at 17:00

  • That seems like it's doing nothing. The command doesn't show error, warning or any message at all. I tried it with lightdm stopped. EDIT: even sudo apt-get --reinstall install lightdm does not offer such dialogue. Apr 19, 2015 at 17:20
  • Try it with gdm instead. Apr 19, 2015 at 17:21
  • Are you sure you have lightdm installed? Apr 19, 2015 at 17:21
