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"

Ubuntu 17.10 review. Running with hidpi, touch screen and wayland support

Ubuntu GNOME 17.10

I think Ubuntu GNOME is the best flavor of Ubuntu if you are running in HiDPI mode 3200x1800 with a touchscreen. All screen captured images are at HiDPI resolution.

Since I prefer the standard gnome-session experience, I installed the "gnome-session" package and rebooted the system. And on the cog icon next to the sign in button, select the "GNOME" instead of ''Ubuntu" option before clicking the sign in button.

sudo apt install gnome-session

Touchpad
I increased the speed, enabled "tap to click", "two finger scrooling". and on gnome-tweak enabled click method to "fingers".
Touch support Ubuntu gnome support for touchscreen is pretty good on the desktop.
Chromium browser supports touch screen very well and much better than Firefox without any plug-ins.
In my Yoga pro 2, the windows key on the screen panel works as the windows key on the keyboard.

Ubuntu 17.10 running on Lenovo Yoga 920 with HiDPI and touch screen support

I resized the windows partiton to the minimun necessary (100G), disabled secure boot and I also remove bitlocker key encryption on windows drive, this allows Ubuntu to see that partition and allow windows to boot with secure boot disabled, without complaning.

This makes everything go easier if you want to keep windows arround on the same disk and dual boot with Ubuntu, you should do this it helps a lot. Even after you disable this, you can re-enable it back, both secure boot and bitlocker key encryption.

Before installing on windows updates resize your windows partition, installing all windows updates will not alow you to gain as much space as possible. After resizing the windows partition to the minimium size you want, install all windows updates, bios and driver updates.

I upgraded all windows updates to the latest version and all drivers to the latest version and upgraded the bios on windows to the latest version before installing Ubuntu, I don't think this makes much differenc…
