Screen becomes really dark sometimes after sleep

Hello,
This is a glitch that I've experienced on Statler as well as Waldorf:
Sometimes, after my laptop screen has gone dark because of idleness, and I try to "revive" it by pressing a few random keys, the screen only goes from black to really dark, so that I can barely make out the windows I had open. I haven't found a way to revert this change, and always have to reboot the OS when it happens.

Do you run nvidia? There is quite a few pages around about similar problems, some here on the forum, and elsewhere.

Nope, I have Intel Integrated Graphics.

I'll have to bump this, since it has happened again several times.

Re: Screen becomes really dark sometimes after sleep

Can't you increase the screen brightness when this happens, using your fn keys, or with something like xbacklight -inc 20?

I didn't know about the xbacklight command and will try it next time, but the keyboard FN keys do not work when this happens.

Re: Screen becomes really dark sometimes after sleep

just sudo apt-get install xbacklight

then xbacklight -dec 30

or xbackligt -inc 30 or whatever, as Mr. rkwurth says.

I find remapping keys or getting them sorted via other fiddles puzzling...
