Re: [Trisquel-users] Toutatis Brightness control

[santiago . lorente]

I typed
"echo 500 > /sys/class/backlight/intel_backlight/brightness"

And just got
"bash: /sys/class/backlight/intel_backlight/brightness: Permission denied"

I also tried with
"sudo echo 500 > /sys/class/backlight/intel_backlight/brightness"

but got the same
"bash: /sys/class/backlight/intel_backlight/brightness: Permission denied"
