Emachine laptop with 2G memory, 2.2Ghz celeron 1k cache, intel cantigia graphics, 64M. Series 525.
I thought this was another video driver incompatability with the new liveCDs, but it turns out the LED backlight goes off.
I can see the PCLinuxOS graphics if I hold it in the sun.
Googling shows similar problems in Emachine and Acer branded laptops.
They say when booting (redacted for love of kittens) distro, to hit the dim/bright controls, and the light will stay on.
This didn't work in this machine. Also in addition to the dark/bright buttons, there is a backlight on/off button.
So maybe some hardware utility needs to be in the kernel or whatever to run.
P.S. I'm going to dual boot install PCLinuxOS in this to see if that works.
