-.SH USING GNOME
+.SH USING GNOME OR UNITY
For the better part of a decade, GNOME shipped xscreensaver as-is,
and everything just worked out of the box. In 2005, however, they
decided to re-invent the wheel and ship their own replacement for
Select "\fIStartup Applications\fP" from the menu (or manually
launch "\fIgnome-session-properties\fP") and add "\fIxscreensaver\fP".
.TP 3
-\fB3: Make "Lock Screen" use xscreensaver.\fP
+\fB3: Make GNOME's "Lock Screen" use xscreensaver.\fP
.EX
sudo ln -sf /usr/bin/xscreensaver-command \\
/usr/bin/gnome-screensaver-command
.EE
+That doesn't work under Unity, though. Apparently it has its own
+built-in screen locker which is not gnome-screensaver, and cannot be
+removed, and yet still manages to be bug-addled and insecure.
+Keep reinventing that wheel, guys! (If you have figured out how to
+replace Unity's locking "feature" with xscreensaver, let me know.)
+.TP 3
+\fB4: Turn off Unity's built-in blanking.\fP
+Open "\fISystem Settings / Brightness & Lock\fP";
+.br
+Un-check "\fIStart Automatically\fP";
+.br
+Set \fI"Turn screen off when inactive for"\fP to \fI"Never."\fP
.SH USING KDE
Like GNOME, KDE also decided to invent their own screen saver framework
from scratch instead of simply using xscreensaver. To replace the KDE
and
.BR xscreensaver-command (1)
mechanisms.
-.SH USING UNITY
-Guess what, they did it again! Ubuntu Unity's screen-locking
-framework is \fIyet another\fP rewrite, and it is completely broken,
-bug-ridden and insecure. At this time I don't have any information on
-how to turn it off and use xscreensaver instead. If you do, let me
-know.
+.SH USING SYSTEMD
+If the above didn't do it, and your system has
+.BR systemd (1),
+then give this a try:
+
+.TP 3
+\fB1: Create a service.\fP
+Create the file \fI~/.config/systemd/user/xscreensaver.service\fP
+containing:
+.EX
+[Unit]
+Description=XScreenSaver
+[Service]
+ExecStart=xscreensaver
+[Install]
+WantedBy=default.target
+.EE
+\fB2. Enable it.\fP
+.EX
+systemctl --user enable xscreensaver
+.EE
+Then restart X11.
+.SH USING UPSTART
+Still not working, but on your distro, that newfangled
+.BR systemd (1)
+nonsense has already fallen out of favor? Then maybe this will work:
+launch the \fIStartup Applications\fP applet, click \fI"Add"\fP, and
+enter these lines, then restart X11:
+.EX
+Name: XScreenSaver
+Command: xscreensaver
+Comment: xscreensaver
+.EE
.SH USING GDM
You can run \fIxscreensaver\fP from your
.BR gdm (1)
new one started. If this is 0, then the graphics hack will never be changed:
only one demo will run until the screensaver is deactivated by user activity.
Default 10 minutes.
+
+The running saver will be restarted every \fIcycle\fP minutes even when
+\fImode\fP is \fIone\fP, since some savers tend to converge on a steady
+state.
.TP 8
.B lock\fP (class \fBBoolean\fP)
Enable locking: before the screensaver will turn off, it will require you
program will suppress the non-existent programs from the list if this
is true. Default: false.
.TP 8
+.B authWarningSlack\fP (class \fBInteger\fP)
+If \fIall\fP failed unlock attempts (incorrect password entered) were
+made within this period of time, the usual dialog that warns about such
+attempts after a successful login will be suppressed. The assumption
+is that incorrect passwords entered within a few seconds of a correct
+one are user error, rather than hostile action. Default 20 seconds.
+.TP 8
.B GetViewPortIsFullOfLies\fP (class \fBBoolean\fP)
Set this to true if the xscreensaver window doesn't cover the whole screen.
This works around a longstanding XFree86 bug #421. See the
.BR xscreensaver\-getimage (1),
.BR xscreensaver\-text (1).
