Gnome sets initial brightness to 0 (completely off)

When starting GDM, my screen fades to black. I have auto-login enabled, so I can just hit the brightness key on my keyboard and bring the brightness back up. However if I disable auto-login, it won't let me use the brightness keys, so I'm stuck with a blank screen.

Any idea how to fix this? How does GDM determine initial screen brightness? Why does it start out by reducing the brightness all the way down?

Re: Gnome sets initial brightness to 0 (completely off)

I have got similar problem, so I will not start a new topic .
When I start notebook, my brightness is set to maximum. When I logout, birghtness set to maximum too. So basically everytime when I get in to the login screen (GDM) brightness is set to maximum.

Any idea how to overwrite this behaviour?

Thanks
