I am using Lubuntu, my desktop environment is lxQt and screensaver is xScreensaver.
I'm trying to figure out a way to switch between users, (e.g. when pressing meta + L).
Even though, it is possible to lock the screen with xscreensaver, I'm unable to use "new login" button and it shows this message:
could not excute "gdmflexiserver": No such file or directory
Update 1
I have come up with something I judge to be a hacky solution: creating a keyboard shortcut that triggers dm-tool switch-to-greeter.
Although, as I said: it's more like a hack than a solution. It also makes me authenticate twice: once for LightDM and another for XScreenSaver, which is not very convenient.
winkey + L, then you're taken to the login screen which works as a lockscreen and user switcher. I want to do this, so I can isolate work profile from personal profile.xubuntu-desktopinto Lubuntu (but you cannot remove it easily, if you change your mind). And then, if you log in 'as Xubuntu', you will get that option when logging out. - I don't know an easy way to do what you want in Lubuntu. I hope someone else can help you ...
