The touchpad on my MBA only registers the left click button. After searching the web, I've found that the patch from might solve the problem. However I'm not sure how to go about applying it. Need some guidance. Thank you.

It's not incredibly detailed but I try and cover some of the basics around patching the kernel here -

You have to apply the patch by yourself and rebuild the kernel... You can find more informations here The wiki has a lot of information about how to do this... Also did u had any freezes, high temperatures, performance issues, unable to make the hdmi to work or any other issues? If yes let me know...

I have followed the steps on but the touchpad problem persists. Probably because I'm rebuilding a 3.9.9 kernel instead of the 3.9.8 kernel. I guess I'll just wait out for the next kernel update. As for other issues, wireless and sound don't work. The machine gets rather hot but after implementing some power-saving features, the heat is reduced. Closing the lid also lead to a black screen upon reopening. (read that it is a brightness issue somewhere)

Touchpad issue still not resolved even after updating to kernel 3.10; it should be solved with that kernel update.. Did not find additional options under 'mouse and touchpad settings', no 2 finger scroll or anything, just 'General' and 'Mouse'. Any advice?

Somehow i missed your reply,

In order to make your mba to have should u must the following entries /etc/asound.conf:

defaults.pcm.card 1 defaults.pcm.device 0 defaults.ctl.card 1

About the temperature issue, what is the output of the dmesg?

Did you see in log something like the following?

ata1.00: failed command: WRITE FPDMA QUEUED ata1.00: cmd 61/08:f0:10:8c:c2/00:00:0b:00:00/40 tag 30 ncq 4096 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1.00: status: { DRDY }

About the touchpad issue, in a few days the patch will be merged with kernel 3.10, i think, so you will not have to build it from the source.

The modification of /etc/asound.conf allows audio to be played through headphones or speakers connected via the jack; still no audio from laptop's speakers. As for the log, didn't encounter the lines you've mentioned. What I got was these:

$ dmesg |grep ata1.00
[    3.070146] ata1.00: unexpected _GTF length (8)
