# This is a small script to adjust brightness at my Dell Latitude via xrand
|
||
|
|
# because xbacklight / wsconsctl doesn't work. It's usually invoked my cwm.
|
||
|
|
# Therefore I have the following bindings configured: #
|
||
|
|
#
|
||
|
|
# bind-key 4-F11 '~/bin/brightness.sh -0.1'
|
||
|
|
# bind-key 4-F12 '~/bin/brightness.sh +0.1'
|
||
|
|
# bind-key C4-F11 '~/bin/brightness.sh 0.5'
|
||
|
|
# bind-key C4-F12 '~/bin/brightness.sh 1.0'
