I have installed MX 16 on my laptop and am quite impressed with it. I usually set the Display Brightness to 50% as it is more convenient for me. What I found is after I restart MX 16, the brightness reverts back to 100% and I will have to reset it to 50% manually. The same thing gets repeated after restarting the OS. Please do something to correct it.
its a quirk in xfce. I use a utility called "xbacklight" to set the brightness level to where I want. in my case, 70%
- Code: Select all
xbacklight -set 70
or should i go like so:
Brightness: acpi_video0 & intel_backlight

Hello. I have some trouble with the brightness controls on my netbook (hardware and software details below):
Fn+F5/F6 seems to use acpi_video0. Fn keys make the brightness change, and the notification popup appear, but don't move the bar in the popup nor the slider in the Power Manager plugin.
Xfce Power Manager v 1.6.1 seems to use intel_backlight when I use the slider or scroll over the panel icon. This way I can get higher max brightness compared to using the Fn keys.
I'd like to use intel_backlight, as it has a bigger max value and is more fine grained (off-topic, anyone knows about the logarithmic scale proposed here, sounded great!), and marginally would like the slider and notification popup update their position properly.
Here's some info from my system:

I tried some of the "popular" acpi options on the grub command line, to no visible effect.

Following advice from old forum posts, I modified these two file, maybe I should just modify one of them?

Option "Backlight" "intel_backlight" # I added this line
Option "TearFree" "true"

Thanks for any help!
