@chapter Overview

@command{unstickpixels} tries to unstick stuck pixels.

Dead (always black) pixels are hard to revive, stuck pixels
on the other hand are more probable to get fixed.

This program should be run under the Linux VT. It works by
cycling the colour on the screen between sRGB(100 %, 0, 0),
sRGB(0, 100 %, 0) and sRGB(0, 0, 100 %), as fast as possible.
If you want to slow down the cycling you can add, as the only
argument, the millisecond time sleep between the colours.


@node Invoking
@chapter Invoking

@emph{Do not used this if you have epilepsia}

@command{unstickpixels} will not run in a graphical environment.
If you are using a graphical environment and do not know how
to access the Linux VT, here is how you do it: press @kbd{Ctrl+Alt+F1},
if this does not open non-graphical login screen, press @kbd{Alt+Right}
until you get one. To get back to graphical environment, hold
down @kbd{Alt+Right} until it appears.

Run @command{unstickpixels} without arguments.
