Upgrade to Ubuntu 11.10 on Acer netbook

I tried to upgrade my Acer Aspire One (AOA150) from Natty to Oneiric, but failed. So, I did a fresh install instead.

Upgrade experience: All seemed fine at first, but somehow the screen went black during the upgrade process and would not come back at all. There seemed to be some activity, so perhaps the upgrade was proceeding fine, but I had no way to tell. So I forced the computer to shut down, downloaded Ubuntu to a USB stick and started a fresh install.

Fresh install: Proceeded without a hitch. Obviously, everything on the computer was wiped out. This would have been a disaster on my main computer, but for the netbook it is fine because there is nothing personal on it, anyway. Only copying the music back onto it will take a bit of time.

Things to do after install: A couple of things to make it work the way I want it to…

Installing Google Chrome (not Chromium):
Download chrome installer, then…
sudo dpkg -i google-chrome-stable_current_i386.deb
sudo apt-get -f install

…the latter to resolve some dependency issues with the browser.

Skype:
Installed skype from the software centre, but microphone wouldn’t work. Sound recorder could record fine, however.
To fix this, I installed pavucontrol, and changed the input to 10 on one side and 90 on the other (after unlocking the left and right channels).
This is explained here: help.ubuntu.com/community/SkypeTroubleshooting

Most built-in mics are mono. The default setting on the Input Control is to lock the R&L channel together. By reading the mono mic as stereo, PulseAudio cancels the input. Click on the middle button on the upper right of the control panel to unlock the R&L channel. Move either the left or right channel to 10 leaving the other channel about 90.

Autologin to 2D:
When setting Ubuntu to automatically login as a user, it defaults to Unity (normal, i.e. with compiz and “3D”). To speed things up, I want it to autologin to Unity-2D. Here’s how:
In the file /etc/lightdm/lightdm.conf, change
user-session=ubuntu to user-session=ubuntu-2d
.. as explained here: askubuntu.com/…/how-to-default-to-unity-2d-on-auto-login

Network:
Luckily the netbook is hooked up to the network by wire, otherwise connecting to wifi would require a password (very annoying when wanting to use autologin). I set wireless to NOT connect automatically.

Final note: I like that in the touchpad settings I can now set it to two finger-scrolling.
