On upgrading from FC6 to FC8 on my laptop, the screen dims almost
immediately at the beginning of the boot up sequence. The screen is
bright for any length of time until the messages shows that the kernel
is booting. Then the screen dims so that text and graphics are barely
discernible. This is true in text as well as graphics modes (runlevels 3
Could be to do with the screen saver - it fades the X gui out before it
starts the screen saver ?
Does anyone know what setup file may be causing this?
Could be that it's sensing low battery power and trying to save power ?
Could be that during boot up ntpd resets the time forward, and the
screen saver noitices there has been no activity for X minutes and
starts the fade out.
