First, to get the sub-woofer to work use the following, but it is a very poor solution so I didn’t implement it in the final laptop setup:<\/p>\n

http:\/\/ubuntuforums.org\/showthread.php?t=2217683<\/a><\/p>\n

I want the lighted keyboard on an ASUS laptop to start at level 1 everytime it boots or resumes\/thaws from sleep\/hibernate. This worked<\/p>\n

I created a conf file in \/etc\/init<\/p>\n

Open directory as administrator<\/p>\n

\/etc\/init<\/code><\/p>\n

Create file<\/p>\n

a.keylights_restart.conf<\/code><\/p>\n

Inside that document paste:<\/p>\n

description \"start keyboard lights\"
\nauthor \"john statler\"<\/code><\/p>\n

start on [2345]<\/p>\n

respawn<\/p>\n

scrip<\/p>\n

su – tech -c “\/sys\/class\/leds\/asus::kbd_backlight\/brightness”<\/p>\n

end script<\/p>\n

Save and reboot. <su\u00a0 – tech> tells the system to run the command as a super user.<\/p>\n

=== more complex but also works ===<\/p>\n

add the command into \/etc\/rc.local<\/code><\/p>\n

or, for an individual user, into\u00a0\u00a0 *home*folder\/.bash_profile (I didn’t have one of these so I skipped it)<\/p>\n

or in cron<\/p>\n

bash -c <\/code>echo 1 > \/sys\/class\/leds\/asus::kbd_backlight\/brightness<\/code> <\/code><\/p>\n

BUT — that wasn’t all, in order to get this to run as per user (the previous command didn’t pass after user log-in)<\/p>\n

This will set the …backlight\/brightness file so it can be written to without super user privileges.<\/p>\n

sudo visudo<\/code><\/p>\n

at the end of the file type:<\/p>\n

ALL ALL = (ALL) NOPASSWD: \/usr\/bin\/tee \/sys\/class\/leds\/asus\\:\\:kbd_backlight\/brightness<\/code><\/p>\n

reboot to have it take effect<\/p>\n

now, to test the script you can run the following from a command line. You can change the 1 to a 3 for instance.<\/p>\n

echo 1 | sudo \/usr\/bin\/tee \/sys\/class\/leds\/asus::kbd_backlight\/brightness<\/code><\/p>\n

I had to actually create a script file and run that from Menu\/Startup Applications
\nCreate file \/home\/your_user_name\/
\nCreate a new text file<\/p>\n

#!\/bin\/bash
\n#
\n# set keyboard lights to level 1
\n#
\necho 1 > \/sys\/class\/leds\/asus::kbd_backlight\/brightness<\/code><\/p>\n

save as keyboard_lights.sh
\nRight-click on new file, select properties\/permissions and allow execution<\/p>\n

Now put the following line into Menu\/Startup Applications under some name like key_lights<\/p>\n

bash -c \"exec \/home\/your_user_name\/keyboard_lights.sh\"<\/code><\/p>\n

==== the following failed to work but here’s the notes====<\/p>\n

That works except for resuming from hibernation or sleep.\u00a0 To get that create 11_keyboard_lights_pm and put in in \/etc\/pm\/sleep.d (the 11 makes sure it runs among the last of the scripts)<\/p>\n

#!\/bin\/bash<\/code><\/p>\n

case \"$1\" in
\nthaw|resume)
\necho 3 | sudo \/usr\/bin\/tee \"\/sys\/class\/leds\/asus::kbd_backlight\/brightness\"
\nesac<\/code><\/p>\n

====\u00a0\u00a0 ====<\/p>\n

if you want to see the command show in a terminal (I might have gotten something wrong) (I honeslty don’t know why this is here)<\/p>\n

mate-terminal bash -c \"echo 1 | sudo \/usr\/bin\/tee '\/sys\/class\/leds\/asus::kbd_backlight\/brightness'; bash\"<\/code><\/p>\n","protected":false},"excerpt":{"rendered":"
