Questions[light-locker](ubuntu)

I do long operations which are steadily getting broken by any power or screen saving utility, so I want to have ubuntu without any power or screensaving programs.

I tried:

sudo apt autoremove --purge light-locker*

OK, I do not want this. I would like to remove light-locker and xscreensaver totally.

Can you help me? :-)

Thanks

PS. What I have found in the meantime:

less /usr/bin/lxlock This is the program/script that starts various external lockers. You can edit it in nano

 sudo nano /usr/bin/lxlock

and put "exit" on the second row, so you computer will not get locked at any time.

It is not a nice way to do it, but it works.

From the given posibillities (man lxlock), I guess the smallest are suckless-tools.

I got it via this strange command:

 sudo apt autoremove light-locker* gconf-service gconf-service-backend gconf2 gconf2-common libart-2.0-2 libbonobo2-0 libbonobo2-common libbonoboui2-0 gnome-power-manager gnome-screensaver gnome-settings-daemon-schemas libjpeg-turbo-progs libpam-gnome-keyring libupower-glib3 i3lock libev4

This installs (sic!) the suckless tools. :-))))

Spurious totally, isn't it? :-)

I'm currently using a fork of Antergos web-greeter because I don't like the default. However I can't use the default screensaver because if I lock through that I can simply press Ctrl + Alt + F7 to circumvent the login and be back in my session (the web-greeter runs on tty8). This is a big problem which I was able to solve by using light-locker. This worked fine until I upgraded to 20.04. Now light-locker won't start because gsd-screensaver-proxy is already running. I tried to solve that by setting the value in org.gnome.settings-daemon.plugins.screensaver-proxy to false. That didn't work. Does anyone know how I can either stop gsd-screensaver-proxy from starting automatically and how to use light-locker instead? I would also be happy if there is a way to ditch light-locker completely and use the default instead.

I just installed Ubuntu 20.04 and then installed xubuntu-core. When prompted, I chose lightdm as my login manager. I then disabled everything I could find related to screen locking, but I still have to enter my password after the screen goes off. Is there some crazy hidden setting I am missing?

I realize I could remove lightlocker, but why in this context does "disable" not mean disable? Is it a bug or a design decision?

I'm experiencing Xorg high CPU usage(90-100%) problem when I unlock session. It keeps going for 5 minutes.

Process that causes problem:

/usr/lib/xorg/Xorg -core :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch

Everything seems working normal except Application Shortcuts and it's very annoying. If I press shortcut to launch terminal it will launch with very long delay(~2-3 minutes).

System:

OS: Xubuntu 18.04
Nvidia Driver Version: 390.77
lightdm 1.26.0

EDIT:

I just found out that same behaviour happens when I plug in USB hub or USB IDE/SATA adapter. 100% CPU keeps for 2-3 minutes. Though it's not happening when I insert USB flash drive.

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

$ 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?

Thanks!
