I can't seem to change the brightness on my LCD display. The default is too dim, cannot see it at all when out of a dark room. But when running Windows (yuck!), it is plenty bright enough.

Is there something in my kernel that needs to be set? Because it starts off dim right after the post (Bright during post).

My kernel config is here

Also, when I try using gamma controls in KDE, it makes no difference at all.

Running Slackware 10.2 (not current) and KDE 3.4 (Full install from CD 1 and 2)

And no, I'm not even gonna try Gnome (not installed, and never will be again)

*** EDIT ***

Oops... Forgot video specs:

i830m Intel Video (8meg standard, 256MB installed)
1024x768 LCD

Bit of a long shot, and you've probably looked in there, but my controls for lcd brightness are in /proc/acpi...(it's a sony vaio laptop)

ok....results:
Seems not to be what it needs.

Any idea what sort of a file it is? if not for the error i'd have thought that's the file, cos on my machine it's /proc/acpi/sony/brightness. Interestingly the "file" command claims that "brightness" is empty, but cat returns the brightness value. Perhaps you could try echoing something into that? No guarantee it won't destroy anything though

i'm running slack 10.2 with the bareacpi.i kernel. i found a descent little program called acpitool, lets me check the full info on my battery, as well as change the lcd brightness.
it doesn't, however, let me suspend on any level. i have to use halt.

Looking into acpitool....

Thanks for the link, but I do not have an Asus or Toshiba, so it doesn't do anything for my LCD

WooHoo! If all else fails, read the directions....

On the Gateway site, it says 'Fn+Up Arrow or Dn Arrow'

And, it worked....lol

LOL! With your post count i'd have expected you to try the fancy fn buttons before anything else:P all's well that ends well

Just goes to show you.....lol

I have a few "Rules on Computer Maintence"

1: Make sure it's plugged in. (Really. We've all done that!!)

2: If it only works when the technician is there, tape a picture of the tech on the inside cover.

3: Turn it on.

4: Read the directions (Even the Windows ones)

I've been messing with mainframes, minicomputers and PC's in various forms since 1973. It just goes to show that sometimes, the manufactures site actually has good info on it.

As for why I never tried the Fn+up: No little green icon on the arrow key. All the other Fn options have it, just not the arrows.

Beat me with a wet noodle.

LMFAO

As for post count: We all need help. We all have questions. None of us has all the answers. But if you know the answer, reply to the thread.

Even better, if you do NOT know the answer, figure it out, then post it. It will benefit you AND others.
