Notes

Wireless

Before doing anything check your wireless card model with

  lspci | grep -i wireless

(You can also tether the wifi, through usb, from an android phone)

Atheros AR9462

There is a known issue (for many Atheros AR9xxx cards) related to the kernel version, see here: http://askubuntu.com/questions/40876/how-do-i-get-an-atheros-ar9287-working

My sugestion is to use

  echo "options ath9k nohwcrypt=1" >> /etc/modprobe.d/ath9.conf

Broadcom 43228

There is a known issue described at the bottom of this page: http://wiki.debian.org/wl, to fix this my sugestion is

  apt-get install laptop-mode-tools

and then “set WIRELESS_BATT_POWER_SAVING=0 within /etc/laptop-mode/conf.d/wireless-power.conf”

HDMI

The first time I tried to use the HDMI (with gnome 3 and pulseAudio) the thing didn't worked, a “dummy device” apeared, to get rid of it use (not with root, with your normal user)

  pulseaudio --kill
  pulseaudio --start

now is working with “Digital Stereo (HDMI) Output + Analog Stereo Input” in the hardware tab of the gnome sound settings

Touchpad

There are two ways to enable it:

  • Press Fn+F7 before logging in.
  • Press Ctrl+Fn+F7 once logged in.

Card reader

In order to make it work I had to place a card in the slot and reboot the system with the card inside.

USB Mouse

The usb mouse freezes, to fix this what I did was to install the `laptop-mode-tools`

  apt-get install laptop-mode-tools

then use

  lsusb

to get the mouse USB ID, something like `abcd:1234`, and then place that in the `AUTOSUSPEND_USBID_BLACKLIST` within the file

  /etc/laptop-mode/conf.d/usb-autosuspend.conf
  

Bluetooth

to fix it (if you have the Atheros AR9462 card) I recommend you read this https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1024884
