With the deprecation of x11-misc/alock-94 I removed alock from my system. Now I cannot lock my screen. I'm using XFCE and configured the shortcut Ctrl-Alt-Del to call "xflock4". Looking at the strace of xflock4 there are stat calls that look for an installed screen lock program: # strace xflock4 | grep stat | grep lock stat("/bin/light-locker-command", 0x7ffd9b27e1b0) = -1 ENOENT (No such file or directory) stat("/usr/bin/light-locker-command", 0x7ffd9b27e1b0) = -1 ENOENT (No such file or directory) stat("/bin/xlock", 0x7ffd9b27e000) = -1 ENOENT (No such file or directory) stat("/usr/bin/xlock", 0x7ffd9b27e000) = -1 ENOENT (No such file or directory) stat("/bin/slock", 0x7ffd9b27e000) = -1 ENOENT (No such file or directory) stat("/usr/bin/slock", 0x7ffd9b27e000) = -1 ENOENT (No such file or directory) stat("/bin/alock", 0x7ffd9b27e000) = -1 ENOENT (No such file or directory) stat("/usr/bin/alock", 0x7ffd9b27e000) = -1 ENOENT (No such file or directory) None of the above commands (light-locker-command, xlock, slock, alock) is a dependency of xfce-base/xfce4-session which contains xflock4. To work properly, at least one of the following packages should be installed as dependency of xfce4-session: x11-misc/alock x11-misc/light-locker x11-misc/slock x11-misc/xlockmore x11-misc/xscreensaver
I came across this bug after a new install of Xfce (unstable) when trying to figure out why xscreensaver was installed on my system. Looking at the xflock4 code (https://git.xfce.org/xfce/xfce4-session/tree/scripts/xflock4), the script first checks the session's xfconf channel for the command to be run (/general/LockCommand). If there is none, it will try, in order, xfce4-screesaver, xscreensaver, gnome-screensaver, xlock, slock, etc. From my testing, a fresh Xfce session does not appear to set anything in /general/LockComand. Since xfce4-screensaver is actively maintained and well integrated in the Xfce project, I would request we pull in xfce4-screensaver as the default when emerging xfce4-session, unless the user manually sets the xscreensaver USE flag.

Not really an acceptable solution since xfce4-screensaver is experimental and far from finished yet, and is hardly what every user wants or likes. A virtual would be the right solution. Also, light-locker needs to be reintegrated to the list of acceptable choices as it was removed for very dubious reasons and is not dead at all, unlike others in the list.
