Hello, ls -al /sys/class//backlight/ intel_backlight ->

ls -al /sys/class/backlight/acpi_video0/ no file xbacklight is installed. To adjust the brightness : Menu => Trinity Configuration Center => Périphériques => Hardware Device Manager => Backlight => Intel HD Graphics 520 and I can adjust the brightness from 0 to 100%, but the value is not keeped if I close the session. The default value = 62%
Hi André, you can install TDE Powersave and then adjust the brightness there. Cheers
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
