As is, we are requesting the screensaver proxy to be started too early
in the login process. One issue that this is causing that login may hang
for a long time, other possible issues appear to be that the screensaver
service is not running at all in the end.

Note that gnome-settings-daemon will request the startup later on.

Thanks to Xiaoguang Wang <xwang@suse.com> for finding this issue and
suggesting a fix!

Closes: #88
