Just to fill you in. I am just a tattooed scooter tramp that has no education and owns a few computers in my motorcycle shop.

So I am no coder. Just self taught is all.

You might get lucky with the below maybe?

No worries -- I appreciate your help.

And my head is spinning right now, so I'm gonna have to leave this alone for a while. Thanks again, and I'll let you know if I turn up anything.

Hey, that worked! I don't know if the screen is brighter at max, but the brightness control actually works now, thru the fn keys and the brightness plug-in. It'll even bring the screen down to full darkness. If I can make the screen a little brighter, that would be nice, but this is an excellent start. Thanks for helping!

Hi,

It seems you have it working, so you may not want to break it...

Not sure if this helps..??

Dave, thank you for the reference! The script:

Code:

sudo setpci -s 00:02.0 f4.b=ff

brightened the screen by two full steps via fn+f5. As noted, that script alone goes away on reboot, but adding it to /etc/rc.local before exit 0 makes it permanent. It was clear on reboot with brightness at max, when the screen ticked up two notches on the login screen. I don't know if it's possible to make the screen brighter still, but it's plenty bright for me.

To sum up:

With Intel graphics, if the brightness controls don't work:

Both of these answers can be considered Best Answer but it seems I can only choose one, and they were equally helpful. My thanks to both rokytnji and Wirezfree (Dave), as well as the authors of the items they linked to, for their help!

Hi Chris_OC,

I suppose there is one last thing you could try, if you have removed it.?
Now you have it at a certain level, try adding back the:

Code:

acpi_backlight=vendor

back in the grub line.

I hadn't removed it (I looked to be sure) so it's cool, but thanks for the thought.
