Acer/Packard Bell is not willing to repair all defects on my
computer, but atleast I can run this for several hours and
try to revive dead 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.

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