Re: color problem

This may happen due to external magnetic interference. See if UPS or any other monitor is kept nearby.

Re: color problem

A video player may be changing the gamma correction setting of the X server. That is
a mapping from pixel level to actual brightness
which affects the apparent brightness of values
between black and full on. It can be set by
the xgamma command or XF86VidModeSetGamma().
See
http://en.wikipedia.org/wiki/Gamma_correction
for more on the topic.
