Default is 1.0. ;brightness=0.9 ; It is also possible to use different settings for day and night ; since version 1.8. ;brightness-day=0.7 ;brightness-night=0.4 ; Set the screen gamma (for all colors, or each color channel ; individually) ;gamma=0.8 ;gamma=0.8:0.7:0.8 ; This can also be set individually for day and night since ; version 1.10. ;gamma-day=0.8:0.7:0.8 ;gamma-night=0.6 ; Set the location-provider: 'geoclue', 'geoclue2', 'manual' ; type 'redshift -l list' to see possible values. ; The location provider settings are in a different section. location-provider=manual ; Set the adjustment-method: 'randr', 'vidmode' ; type 'redshift -m list' to see all possible values. ; 'randr' is the preferred method, 'vidmode' is an older API. ; but works in some cases when 'randr' does not. ; The adjustment method settings are in a different section. adjustment-method=randr ; Configuration of the location-provider: ; type 'redshift -l PROVIDER:help' to see the settings. ; ex: 'redshift -l manual:help' ; Keep in mind that longitudes west of Greenwich (e.g. the Americas) ; are negative numbers.

The variables are device-specific. Run
synclient with no
arguments to see the options available for your device.
The negative values for
VertScrollDelta are what invert the direction of the scroll
for natural scrolling.

For the screen brightness controls, create the following script under
#!/bin/bash set -e # Modify this to point to your monitor device. # A good starting point is `ls /sys/class/backlight`. # https://wiki.archlinux.org/index.php/backlight file="/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight/brightness" current=$(cat "$file") new="$current" if [ "$1" = "-inc" ]; then new =$(( current + $2 )) fi if [ "$1" = "-dec" ] then new=$(( current - $2 )) fi echo "$new | tee $file"
Now configure sudo to be able to run the script as sudo without
entering a password. We will want this since we will be calling this
script by pressing on the screen brightness keys. Run
sudo visudo and enter the following line at the end of the
file (replace “user” with your user name):
user ALL = (root) NOPASSWD: /home/user/.scripts/backlight.sh
Show menu before boot
/etc/default/grub GRUB_TIMEOUT_STYLE=menu GRUB_TIMEOUT=3
$ sudo update-grub
Ubuntu likes to boot straight into the OS.
SHIFT keys do not work on my setup. Edit the grub config as
shown above to get the menu by default and set a timeout of 3 seconds on
Keyboard not detected
/etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.reset=1"
$ sudo update-grub
My ASUS laptop keyboard was not recognized on a cold boot. The
solution on my setup was to add
i8042.reset=1 to the kernel
Test the setting first by booting as usual and pressing
e at the boot menu. Then, edit the kernel parameters

configuration file and run
update-grub to apply the changes
