You can too -
From what I remember of my basic programing, the computer and operating system didn't matter for memory locations. My memory is probably wrong. It usually is.
Sometimes you have to ask the dumb questions first to get enough info to start asking intelligent ones.
Ok, info on the system.
Acer Aspire 7741Z-5731
OS is PCLOS 2011
I've run into several articles on how to fix this, but none seem to work for me. I did find one that had me add a line to the etc/grub/default file. I turned the brightness all the way down, but then I couldn't turn it up.
I did discover that if I go into Winders and turn the brightness down, then reboot into PCLOS, the brightness stayed down to the level I set in Windows.
