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
