Turns out I still ran into trouble. After using Unity 2D, I finally decided to give xubuntu another chance (tried it years ago). I was impressed and how much it had improved (more polish), while...
I may have found a solution to the external monitor problem. Previously, I've had to run Ubuntu 2D because my screen would freeze using the default Unity. While addressing a video tearing issue, I...
I also have the lag, though I am reluctant to switch drivers because with wl, I get a better signal and power management settings work. I'd like to hear if anyone has worked around these issues with...
Ditto on the external monitor. I'm connecting via thunderbold/hdmi and having to use Ubuntu2D to function in 12.04. In 11.10 I could use the 3D desktop and just closing and opening (not suspending...
Is there anyone switching between laptop and external monitor that is not having this problem? I did find that if I suspend to disk and resume the external monitor will work again. I'm not sure if...
After applying Other Power Saving Tips (thanks Poliva), I can get the power usage just under 8 watts in ideal circumstances. This is still nearly 3 watts above OS X. I've tried different approaches...
As a follow up on this message, I consistently see this same problem. After resuming from suspend (with nothing connected to the laptop), I plug into an external monitor via HDMI and see nothing but...

Here's some screenshots. I used XBattery to measure the voltage and current. For this particular test I really tried to get low readings by turning down the monitor brightness to...
I'm having problems resuming too. I typically get a screen with just the background image and no menus. Sometimes if I go to a VT and restart lightdm (sudo restart lightdm), it helps and sometimes...
I had a similar experience. I switched over to OS X and tried a few utilities to measure the discharge rate. With similar settings (same screen brightness, wifi enabled, etc), I'm seeing 5.5 watts...

I edited the wiki here: https://help.ubuntu.com/community/MacBookAir4-2#GPUPower
Thanks again.
@jonny
That worked! Thank you!
My new readings, a drop of nearly 10C:

I've completely shutdown graphics (sudo lightdm stop), run powertop and i7z and shut down some offenders (like the sound modules) and still I've got high temps. Here is the output from...
@jonny
The air temp is 21C. Are you running Unity with Compiz? Mine's an 13" i5 also.
First, a thanks for all those who put in work to get Ubuntu running on the MBA 4,2. I'm generally pleased with how it is running after following the setup instructions here...
