3 xteevee - Simulate various TV problems
6 [\-display \fIhost:display.screen\fP] [\-window] [\-root] [\-install]
7 [\-visual \fIvisual\fP]
9 [\-static] [\-no-static] [\-roll] [\-no-roll] [\-bars] [\-no-bars]
12 simulates various television problems, fondly re-creating the days when
13 computers were fun and I spent my time with an Atari 400 hooked up to a
14 black-and-white TV I found in someone's trash.
18 picks a mode to display from the available options. If modes are explicitly
19 set on the command-line, they override the implicit options and will be
20 chosen among exclusively. If modes are explicitly excluded from the
21 command-line, the they are simply removed from contention.
23 The image that it manipulates will be grabbed from the portion of
24 the screen underlying the window, or from the system's video input,
25 or from a random file on disk, as indicated by
26 the \fIgrabDesktopImages\fP, \fIgrabVideoFrames\fP,
27 and \fIchooseRandomImages\fP options in the \fI~/.xscreensaver\fP

34 for a more sophisticated (but more graphics-intensive) implementation
38 accepts the following options:
41 Draw on a newly-created window. This is the default.
44 Draw on the root window.
47 Install a private colormap for the window.
49 .B \-visual \fIvisual\fP
50 Specify which visual to use. Legal values are the name of a visual class,
51 or the id number (decimal or hex) of a specific visual.
54 Cycle through all the available modes. This is the default.
60 Explicitly select the "static" mode.
63 Explicitly forbid the "static" mode.
66 Explicitly select the "vertical roll" mode.
69 Explicitly forbid the "vertical roll" mode.
72 Explicitly select the "color bars" mode.
75 Explicitly forbid the "color bars" mode.
80 to get the default host and display number.
83 to get the name of a resource file that overrides the global resources
84 stored in the RESOURCE_MANAGER property.
86 Notable X resources supported include the following:
92 are booleans, defining which modes are to be implicitly available if
94 is run without command-line mode selections.
96 is a boolean, defining if
98 should cycle through each available mode or pick one and stick with it.
102 are integers, defining how long each mode should be displayed and how
103 long the time between them should be if
107 is an integer, defining the strength of the signal during the "static"
108 mode, as a percentage.
111 should simulate more TV problems.
