In Ubuntu 16.04 on my Lenovo ideapad 510s, I can use F11/F12 to get 22 different levels of brightness from virtually blank (1) to max (535), but from manually setting the level in /sys/class/backlight/intel_backlight/brightness
I know my hardware supports far more than that. When I use the hotkeys, brightness
changes by a somewhat arbitrary 26 either way. Is there a way I can change that interval of 26 to something more like 5 or 10?
The suggestions I have found so far involve adding acpi_backlight=vendor
to default/grub
, which completely disables my adjustments, or installing xbacklight, which was unresponsive and would just be a workaround at best. The first answer here is close to what I was looking for, but it's specific to KDE.
