Useful Commands for Running Ubuntu on a Macbook

Note: These are based on Ubuntu 12.04 on a Macbook 7,1.

To control the keyboard backlight, use
```
echo 0 | sudo tee -a /sys/class/leds/smc::kbd_backlight/brightness
```
0 turns it off, 255 is fullest brightness.
By default, the headphone jack has a bright red LED shining in it. This turns it off.
```
amixer set IEC958 off
```
Some commands to make the trackpad perform like it does in OS X. The first disables tap-to-click completely, the second allows horizontal scrolling, and the last supposedly tries to stop accidental palm presses (though its not foolproof).
```
synclient MaxTapTime=0
synclient HorizTwoFingerScroll=1
synclient PalmDetect=1
```
If the Macbook won't goto sleep automatically when the lid is closed, you can run the following before closing it.
```
sudo /etc/acpi/sleep.sh
```
Alternatively, install package uswsusp, and run the following.
```
sudo s2ram --force
```
