This manual page documents briefly the xflip, and
meltdown commands. This manual page was written for the Debian
GNU/Linux distribution (but may be used by others), because the original
program does not have a manual page.
The programs play with the X display, producing some interesting
effects. One traditional use of these commands is to have them run and
affect someone else's X display, as a practical joke.
- -display
displayname
- The X display to operate on.
- -planes
- Operate on a singleplane at a time.
- -vert
- Flip the screen vertically.
- -oblic
- Flip the screen vertically and horizontally at the same time.
- -random
- Flip small random pieces of the screen instead of the while display.
- -times
number
- Specifies the number of pieces of the screen to flip when -random is used.
Default is 300.
- -delay x
- Meltdown may run too fast on fast computers to be fully appreciated; this
can be used to slow it down. If specified, every x times the display is
updated, a 1 microsecond delay will be inserted. The default is no delay
at all. Reasonable values for x are in the 20 to 200 range.
- -wait n
- Makes meltdown wait for n seconds after the screen is totally black. If
you pass 0 to -wait, it will wait until you press a key or mouse
button.
