Installing Ubuntu 12.04 (Precise Pangolin) on a ThinkPad X220
This is the same machine on which I previously installed Ubuntu 11.04. For this LTS release I decided to do a clean install rather than an upgrade from 11.10.
With every release of Ubuntu, more and more aspects of the system work correctly without any manual intervention. Here is a summary of what I nevertheless had to do to get the machine back to the way I like it.
- Associate my bluetooth HIDs
- Adjust display layout
- Problem: With some layouts the machine hangs! Will look into this.
- Adjust touchpad
- Switch to two-finger scrolling
- Disable mouse clicks
- Disable Unity automaximization
- Install and run gconf-editor and set apps|compiz-1|plugins|grid|screen0|options|top_edge_action to 0 (originally 10).
- Install compizconfig-settings-manager and run ccsm:
- Assign the Resize Windows function to Alt-Button3 which is easier than the default
- Enable terminal bell:
- Run gconf-editor and use it to change desktop | gnome | peripherals | keyboard | bell_mode from "off" to "on"
- Add "pactl upload-sample /usr/share/sounds/gnome/default/alerts/glass.ogg bell.ogg" to .xprofile
- Add "[ "$DISPLAY" ] && xset b 100" to ~/.bashrc
- Install tp-smapi module
- Install the tp-smapi-dkms package
- Add "tp-smapi" to /etc/modules
- Install HDAPS stuff:
- Add "hdaps" to /etc/modules
sudo add-apt-repository ppa:linrunner/thinkpad-extras sudo apt-get update sudo apt-get install hdaps-utils sudo modprobe hdaps hdaps-gl
- In /etc/sudoers add "Defaults timestamp_timeout=0"
(Without this, every program I run after executing any command with sudo also effectively has full root privileges. This is ungood. If I want to run a sequence of commands as root without having to authenticate every time I'll just do "sudo su" to start a root shell!)
- Enable fingerprint reader as I described here:
sudo add-apt-repository ppa:fingerprint/fprint sudo apt-get install libpam-fprintd fprintd fprintd-enroll sudo vi /etc/pam.d/lightdm
- Set up hotkeys (zoom and micmute) as I described earlier
- Move documents, pictures and other personal files from old to new home directory
- Set desktop background image
- Set up Empathy accounts, etc.
