Ubuntu 12.4 install notes

Also related with install of Ubuntu 12.04 is my other post  Ubuntu 12.04 review on Lenovo Q150.

Add medibuntu repositories by running the commands below and use Software center to add the packages you need.

sudo -E wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get --quiet update && sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring && sudo apt-get --quiet update

sudo apt-get install app-install-data-medibuntu apport-hooks-medibuntu

For MacBookPro users

Download the mac 12.04 iso for 64 bit (for EFI boot support) and boot your mac with it, it's the easiest method.

Sensors (temps & fans)

To enable proper detection of sensors edit /etc/modules:

gksudo gedit /etc/modules

Add to this to end of file, save and reboot:

coretemp

Bug report filed to track this not being part of the stock install.

To get the Macbook fans to work properly you will need to enable the Mactel PPA and install macfanctld.

sudo add-apt-repository ppa:mactel-support/ppa
sudo apt-get update && sudo apt-get install macfanctld

For more info on macfanctld

man macfanctld

Temperature, fanspeed, environmental light and keyboard backlight can be controlled over the sysfs exported interface at /sys/devices/platform/applesmc.768/.

edit your to look like this /etc/macfanctl.conf

# Config file for macfanctl daemon
#
# Note: 0 < temp_X_floor < temp_X_ceiling
#       0 < fan_min < 6200       

fan_min: 2000

temp_avg_floor: 36
temp_avg_ceiling: 55

temp_TC0P_floor: 50
temp_TC0P_ceiling: 58

temp_TG0P_floor: 50
temp_TG0P_ceiling: 58

# Add sensors to be excluded here, separated by space, i.e.
# exclude: 1 7
# will disable reading of sensors temp1_input and temp7_input.

exclude:

# log_level values:
#   0: Startup / Exit logging only
#   1: Basic temp / fan logging
#   2: Log all sensors  

log_level: 0

Wireless card

The Broadcom driver was not installed by default, you either need to connect your MacBookPro to the internet and allow the installer to download updates while installing. Or use System->Administration->Additional Drivers to install the STA drivers.

Sometimes it won't allow you to install the Drivers from "Additional Drivers" (specially with PAE Kernel) So, you will need to install the firmware manually:

sudo apt-get install firmware-b43-installer b43-fwcutter

Then, you need to reinstall bcmwl: 

sudo apt-get install --reinstall bcmwl-kernel-source

Touchpad (bcm5974)

The touchpad works out of the box. Uncheck the "Enable mouse clicks with touchpad" checkbox under the Touchpad tab, and enable two-finger scrolling from the preference->mouse->touchpad applet. Then the touchpad will work just like in OSX. Clicking and holding with one finger and dragging with the other work like a dream. Furthermore tweaking the drag and drop time to be less may be help. 

LCD Brightness Control

(taken fromhttp://www.voria.org/forum/viewtopic.php?f=3&t=1091):

If backlight control does not work for you, follow these instructions, this also enable PowerControl for the screen using the nvidia driver to keep temp down and battery life longer:

• Edit the file '/etc/X11/xorg.conf' and add this line into the Device section:

• Option  "Coolbits" "1"
  Option  "RegistryDwords" "EnableBrightnessControl=1; PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefaultAC=0x3"
