I have installed Ubuntu 18.04 but found gnome too heavy for my old hardware.
So I installed Xubuntu-desktop:
sudo apt-get install xubuntu-desktop synaptic sudo apt-get remove gdm3 sudo dpkg-reconfigure lightdm sudo apt-get remove nautilus nautilus-* gnome-power-manager gnome-screensaver gnome-termina* gnome-pane* gnome-applet* gnome-bluetooth gnome-desktop* gnome-sessio* gnome-user* gnome-shell-common zeitgeist-core libzeitgeist* gnome-control-center gnome-screenshot && sudo apt-get autoremove
It worked beautifully, but now, sometimes xscreensaver locks my screen, sometimes lightlocker does.
I have them both installed, apparently:
$ sudo dpkg -l | grep locker rc gnome-screensaver 3.6.1-8ubuntu3 amd64 GNOME screen saver and locker ii light-locker 1.8.0-1ubuntu1 amd64 simple screen locker for lightDM display manager ii light-locker-settings 1.5.0-0ubuntu2 all simple configuration tool for light-locker $ sudo dpkg -l | grep xscreen ii xscreensaver 5.36-1ubuntu1 amd64 Screensaver daemon and frontend for X11 ii xscreensaver-data 5.36-1ubuntu1 amd64 Screen saver modules for screensaver frontends $
This is my production workstation and I'm afraid of messing it.
Having them working at the same time presents no huge problem for me, but it looks inconsistent.
I have a "Lightlocker settings" icon on my "Settings" app, but it doesn't work. So I can only configure sleep timeouts for xscreensaver. Would it be safe to remove xscreensaver (which is uglier)? And is there a way to make "Lightlicker settings" actually work and allow me to configure its timeouts? Or should I keep xscreensaver and remove lightlocker?
