you can install TDE Powersave and then adjust the brightness there.

Hello Slavek,
It's what I did, "tde-powersave" installed.
Where to adjust the brightness ?
Only this solution :
Menu => Trinity Configuration Center
=>Peripheral devices => Hardware Device Manager
=> Backlight => Intel HD Graphics 520
I can adjust from 0 to 100%,
but the value is not saved if I close the session or reboot.
The default value = 62%.
When the computer pause begins (45min), the brightness becomes 5%,
so low that I have to reboot the computer.
My video card is Intel HD 520, but not dedicated,
works with the processor and the RAM.
Before, I could do that by "left button mouse",
Desktop configuration => Display => Energy Control.
But, this possiblity has disappeared, only gamma configuration.
With another laptop, dedicated video card, (nvidia or ATI), it works fine.
Thanks, regards,
André
