BCM4306
The BCM4306 wireless card is a known troublemaker. However, the b43
driver has vastly improved over the last couple of years and should support this chip without issue. We'll just need to add the appropriate repository. Run the following in a terminal:
sudo -i cat << EOF >> /etc/apt/sources.list.d/b43.list deb http://ports.ubuntu.com/ubuntu-ports/ precise multiverse deb-src http://ports.ubuntu.com/ubuntu-ports/ precise multiverse EOF apt-get update && apt-get purge -y bcmwl-kernel-source broadcom-sta-common broadcom-sta-source apt-get install b43-fwcutter firmware-b43-installer
And reboot the system.

Battery monitor
To enable the battery monitor for the current session:
sudo modprobe pmu_battery
To enable it permanently for all sessions, edit the file /etc/modules:
sudo nano /etc/modules
or
gksudo gedit /etc/modules
and add the following line:
pmu_battery
Save and exit, and battery monitor should work on reboot.
CPU frequency scaling
(Source: https://wiki.ubuntu.com/PowerPCFAQ#How_can_I_use_powernowd_for_CPU_frequency_scaling.3F)
To reduce CPU power consuption in G3 and G4 laptops, replace the default 'ondemand' kernel governor with 'powernowd'. First, install the powernowd package:
sudo apt-get install laptop-detect wget -P/tmp http://ports.ubuntu.com/ubuntu-ports/pool/universe/p/powernowd/powernowd_1.00-1ubuntu5_powerpc.deb sudo dpkg -i /tmp/powernowd_1.00-1ubuntu5_powerpc.deb
The powernowd package is also available from the Ubuntu Software Center interface.
Finally, disable the ondemand governor:
sudo update-rc.d ondemand disable
Display sleep

Right-click emulation
Ubuntu's default right-click is F12, which is unorthodox and inconvenient. To add the customary MacOSX key control-click, edit the file /etc/default/mouseemu:
sudo nano /etc/default/mouseemu
and uncomment the line
RIGHT_CLICK="-right 29 272"
Reboot to enable the new right-click mapping.
