xteevee - Simulate various TV problems
xteevee [-display host:display.screen] [-window] [-root] [-install]
[-visual visual] [-cycle] [-no-cycle] [-static] [-no-static] [-roll]
[-no-roll] [-bars] [-no-bars]
xteevee simulates various television problems, fondly re-creating the
days when computers were fun and I spent my time with an Atari 400
hooked up to a black-and-white TV I found in someone's trash.
When run, xteevee picks a mode to display from the available options.
If modes are explicitly set on the command-line, they over-ride the
implicit options and will be choosen among exclusively. If modes are
explicitly excluded from the command-line, the they are simply removed
The image that it manipulates will be grabbed from the portion of the
screen underlying the window, or from the system's video input, or from
a random file on disk, as indicated by the grabDesktopImages, grabVide-
oFrames, and chooseRandomImages options in the ~/.xscreensaver file;
see xscreensaver-demo(1) for more details.
See also xanalogtv(1) for a more sophisticated (but more graphics-
intensive) implementation of this concept.
xteevee accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
-cycle Cycle through all the available modes. This is the default.
Don't cycle modes.
-static Explicitly select the "static" mode.
Explicitly forbid the "static" mode.
-roll Explicitly select the "vertical roll" mode.
Explicitly forbid the "vertical roll" mode.
-bars Explicitly select the "color bars" mode.
Explicitly forbid the "color bars" mode.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
Notable X resources supported include the following:
static, roll and bars are booleans, defining which modes are to be
implicitly available if xteevee is run without command-line mode selec-
tions. cycle is a boolean, defining if xteevee should cycle through
each available mode or pick one and stick with it. delayMode and
delayBetween are integers, defining how long each mode should be dis-
played and how long the time between them should be if cycle is on.
staticSignal is an integer, defining the strength of the signal during
the "static" mode, as a percentage.
xteevee should simulate more TV problems.
