Trusty Tahr 14.04 LTS, seems to be fully updated
f.lux also has no effect.
Also when i try to do
sudo echo 50 > /sys/class/backlight/acpi_video0/brightness
then it says 'bash: brightness: permission denied'.

I would love to help provide some more help on my dual monitor setup.
I found this documentation: https://wiki.ubuntu.com/X/Config/Resolution
It says I should run $gnome-display-properties. Seems to be out of date.
gnome-display-properties: command not found
I guess it would be annoying to say it's a security vulnerability although if my screen isn't dim someone could more easily look through the window and see what I am typing on the screen. |
Trusty Tahr 14.04 LTS, seems to be fully updated.
The problem is: When I go to System Settings -> Brightness & Lock, the slider has no effect. I can decrease the brightness slider to any level and the actual brightness of the monitors apparently does not change in any way.
f.lux also has no effect.
Also when i try to do
echo 50 | sudo tee /sys/class/backlight/acpi_video0/brightness
it has no effect
(I learned why i can not do
sudo echo 50 > /sys/class/backlight/acpi_video0/brightness, so that is good.)

f.lux - I was saying this doesn't work either, but I found out it doesn't really install correctly, and it gives error messages when I try to start it, so that doesn't mean much. redshift does work, so my monitors are not completely insensitive or broken ...
