Following is the different quirks I had to work out to get Ubuntu desktop 9.04 properly configured onto my new Asus K70io laptop.
1. Wireless network didn’t work.
Ubuntu didn’t recognize the wireless network card.
I ran lspci to get information on which wireless network controller I was using
This returned among other PCI devices:
04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
This discussion thread solved my problem by running:
# apt-get install linux-backports-modules-$(uname -r)
and then restarting Ubuntu.
2. Touchpad not recognized as a touchpad in the Mouse configuration.
3. Setting the proper resolution
When starting the System > Preferences > Display I couldn’t choose the correct resolution for my screen which was 1600×900.
I opened System > Administration > Hardware Drivers. From there I chose to install the proprietary Nvidia display driver. That resolved the resolution issue.
