Black screen... Possibly Kernel problem?

griffinwebnet · 11-30-2011, 05:42 PM

Hi all. I posted this in question in the OS questions area before but as iv now discovered it isnt exclusive to backtrack, im posting here instead. I linked to this thread there as well so if mods could delete that thread that would be awesome.

Now the problem i was having was that after booting Backtrack 5 & BT 5 R1 i would see the splash screen and then the screen would go black, and not like blinking terminal plack as in OFF, but after i stuck a flashlight against the LCD i could see that the interface and gui were there, the LCD's backlight was simply off. I assumed that BT was responsible but now that i have tried Blackbuntu ubuntu 11.04, i have come to the conclusion that something must be wrong with the kernel, or at least it is no longer comaptible with my monitor for some reason. see i can run backtrack 4 r2 and i can run ubuntu 10.10 both of which use linux kernel 2.6.35

Backtrack 5 and ubuntu 11.04 and 11.10 and blackbuntu all use kernel 2.6.38. Is it bossible that somewhere along something was removed from the kernel that is essential to my system running?

I am posting this HERE because i am on a laptop. specifically an Acer Aspire 5734z and am having problems with the built-in monitor.

Are there hardware brightness controls (many laptops have them) and have you tried adjusting them?

If not, see whether you can disable them in the BIOS.

There are controls for that and i have tried i even tried the button built in on the laptop to switch the backlight on and off to no avail.

aaliyahaash, it might be best to start your own thread, unless you are here just to spam for m3tube dot com.

Be sure to include the error messages you are getting.

Hi,

I bought a laptop yesterday and also got black screens... looking in Forums I found you. Also, I have a solution which is not nice but it works. After I boot linux, I press Fn+3 a few times (there is a sun symbol, may be another key for you). When you press it, the backlight will appear again. Hope this solves... but I want this to be automatic in init.d or xorg.conf, but have no knowledge... I'll post another issue for that.
