13
15 The gltext program draws some text spinning around in 3D, using a font
16 that appears to be made of solid tubes.
17
19 gltext accepts the following options:
20
21 --window
22 Draw on a newly-created window. This is the default.
23
24 --root Draw on the root window.
25
26 --window-id number
27 Draw on the specified window.
28
29 --install
30 Install a private colormap for the window.
31
32 --visual visual
33 Specify which visual to use. Legal values are the name of a
34 visual class, or the id number (decimal or hex) of a specific
35 visual.
36
37 --text string
38 The text to display. This may contain newlines, but it
39 shouldn't be very long. The default is to display the machine
40 name and OS version.
41
42 This may also be a format string acceptable to date(1) and
43 strftime(3), in which case, it will be updated once a second.
44 So to make this program display a spinning digital clock, you
45 could do this:
46
47 gltext -text "%A%n%d %b %Y%n%l:%M:%S %p"
48
49 To include a literal `%', you must double it: `%%'.
50
51 See the man page for strftime(3) for more details.
52
53 --program command
54 The given program is run, and its output is displayed. If
55 specified, this overrides --text. The output of this program
56 will be repeatedely displayed, with new pages of text shifting
57 in every few seconds. Lines should be relatively short. You
58 might try:
59
60 -program 'xscreensaver-text --cols 20'
61
62
63 --maxlines
64 Set the number of lines of text to display. By default, gltext
65 will print 8 lines of text at a time. Use this option to in‐
66 crease or decrease that number. Be aware that gltext is de‐
67 signed to work with a fairly small amount of text, so setting
68 this value too high might result in slow performance or strange
69 behaviour stemming from buffer overflows. Increase at your own
70 risk.
71
72 --mono Display the text in a monospace font. Default is a variable-
73 width font.
74
75 --no-mono
76 Display the text in a variable-width font. This is the de‐
77 fault.
78
79 --wander
80 Move the text around the screen. This is the default.
81
82 --no-wander
83 Keep the text centered on the screen.
84
85 --wander-speed
86 Sets the speed at which the text wanders around. Default is
87 0.02.
88
89 --spin Which axes around which the text should spin. The default is
90 "XYZ", meaning rotate it freely in space. "--spin Z" would ro‐
91 tate the text in the plane of the screen while not rotating it
92 into or out of the screen; etc.
93
94 --no-spin
95 Don't spin the text at all: the same as --spin "".
96
97 --front When spinning, never spin all the way around or upside down:
98 always face mostly forward so that the text is easily readable.
99
100 --no-front
101 Allow spins to go all the way around or upside down. This is
102 the default.
103
104 --wireframe
105 Render in wireframe instead of solid.
106
107 --fps Display the current frame rate, CPU load, and polygon count.
108
109 --scale Sets the scale at which the text is rendered. Bigger values
110 will result in bigger text; smaller values will result in
111 smaller text. The default value is 0.01.
112
114 DISPLAY to get the default host and display number.
115
116 XENVIRONMENT
117 to get the name of a resource file that overrides the global
118 resources stored in the RESOURCE_MANAGER property.
119
120 XSCREENSAVER_WINDOW
121 The window ID to use with --root.
122
124 X(1), xscreensaver(1) xscreensaver-text(6x)
