Description nicolas+freedesktop 2016-09-15 05:43:45 UTC
On Gnome 3, xdg-screensaver fails to suspend the screensaver if xprop is not installed.

Without xprop the $screensaver_file is not created (as xdg-screensaver cannot retrieve the window ID), and so the "inhibitor" placed on the session via DBus expires after the 10s sleep in the Perl DBus script loop.

while (1) {                                                                     
  my $status = new IO::File($screensaver_file, "r")                             
    or exit 0;                       

xdg-screensaver seems to try to support the case where xprop is not installed (It checks for xprop, and various functions bail out early if it's not available). However with Gnome 3 (and perhaps with other environments) it seems it's a hard requirement, and as such the user should be warned if it's missing.

I believe that affects numerous users as there have been several reports of xdg-screensaver failing with Gnome in various projects:
