This has been confusing the hell out of me for quite some time now and the guys at the PCLOS forums are not being very helpful. Here are the specifics: ...

Laptop screen turning off during boot
Here are the specifics:
Laptop: Gateway Model MX3228 (Click HERE for Specs)
Attempted to install PCLinuxOS LXDE Mini (fresh download and burn, MD5 checks out)
The story so far...
Originally, I had PCLinuxOS Enlightenment installed. However, that particular distro is nearly 3 years old and when I attempted to upgrade it I broke everything. On the PCLOS forums they suggested installing LXDE mini and then installing the packages for Enlightenment. So I downloaded LXDE Mini and attempted to install. That's when all hell broke loose
During boot the laptop's screen goes dark. I say "goes dark" because at just the right angle with just the right amount of light you can make out what is being displayed. It is as if the back-light has been turned off but the monitor is still displaying data.
I tried every single boot option given to me in the bootloader. Not a single one stopped the screen from going dark. I tried pressing FN+F4 thinking it might be shunting the display to the external VGA port, but there was no effect. I plugged in a monitor to the external VGA port. The external monitor remained off if plugged in during or after boot. However, when plugged in before boot it turned on and remained on.
Using the external monitor I managed to install PCLOS to the harddisk. After restarting, I looked around in the settings. Particularly the video card settings. While fiddleing with those settings I changed the Monitor to plug'n'pray. A flash and suddenly the laptop monitor lights up. I save my settings thinking I have fixed the problem and restart. On restart the screen goes dark.
So, in short, selecting "Plug'n'Play" for the monitor in the video configuration dialog will turn the monitor on. On boot, the monitor turns off EVERY TIME. No setting that I can find will stop this
Someone, please HALP!

Have you tried switching tty during boot up? Press Alt+Ctrl+F2 to F6. Check if any useful output being displayed in any tty.

I think it is the distro calling for power settings the laptop does not have, but I could be mistaken on that. This is a pickle I tell ya what.
I have the laptop loaded up now, if you have any commands you want me to feed it that could give you any more info please dont hesitate to tell me. I will try anything at this point
EDIT: NEW INFO: So I logged into the laptop via the external monitor and let it set for about 15-20 minutes. Enough for the screensaver to kick on. I pressed a button and POOF the backlight came on like nothing happened. Now I am positive this has something to do with power settings. Note there are no power settings in the BIOS that I can find.

no I have not. do I just type nomodeset in the kernel options at the bootloader?
EDIT: because, if that is so, it does not work. boots like normal, backlight still turns off
