[Pkg-xfce-devel] Bug#870207: light-locker-command --lock returns 0 without locking (breaks slock)

[Daniel Shahaf]

Package: light-locker
Version: 1.7.0-3
Severity: serious
Justification: breaks unrelated software

Dear Maintainer,

On my system, 'light-locker-command --lock' returns 0 without doing
anything.  I presume that is because there no 'light-locker' process is
running (due to #858445).  In case it's relevant, I don't use lightdm
either; I login by running 'startx' in a vt.

That breaks the Ctrl+Alt+Del (lock screen) combination in xfce4, which
defaults to running xflock4.  xflock4 invokes a number of screen lockers
and exits whenever any one of them returns true:

    % sh -x /usr/bin/xflock4
    + PATH=/bin:/usr/bin
    + export PATH
    + xscreensaver-command -lock
    + light-locker-command --lock
    + exit
    (the screen did not lock)

Could the --lock option please learn to return non-zero when it did not
lock the screen.   This way, xflock4 would start working again.

Thanks,

Daniel

P.S. My /usr/bin/xflock4 comes from xfce4-session/4.12.1-5.
