I'd like to be able to have my KDE session started with lightdm auto login but lock immediately. But if I logout and then back in, I don't want the lock.
I found this bug:
https://bugs.kde.org/show_bug.cgi?id=300151
I'm currently using the solution in comment #4, (setting DESKTOP_LOCKED in .xprofile), but this always locks the screen, even if it wasn't an auto-login.
According to the links in comment #9 in the bug, autologin-in-background should do what I want. But it doesn't; using the following /etc/lightdm/lightdm.conf, the autologin proceeds on another screen, but it is not locked. All you have to do is switch to that screen (Ctrl-Alt-F8), no password required. Any idea what's wrong?
