Dell e6330 Linux Ubuntu installation

Some trouble running Ubuntu raring on the Dell e6330 out of the box... here are my solutions.

Wireless doesn't work out of the box. My e6330 contains a Broadcom BCM43228 chip. To install a driver these commands:

sudo apt-get install ubuntu-restricted-extras ubuntu-restricted-addons linux-headers-generic linux-firmware-nonfree
sudo apt-get install bcmwl-kernel-source

Optionally install this as well

sudo apt-get install broadcom-sta-common
#and reboot
sudo reboot

Mouse sensitivity

I couldn't work with the touchpad on the laptop and I had a hard time finding a fix for that. I found someone advising the following command which fixed it for me:

xset m 50 1

Audio Output

Built-in speakers didn't work. I think I fixed it by setting the mixer settings right:

# set mixer settings right
alsamixer
# test
aplay /usr/share/sounds/alsa/Front_Center.wav

No further issues... yet
