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 configuration becomes easier. Here is a summary of what I had to do to get the machine back to the way I like it.
- Move documents, pictures and other personal files from old to new home directory
- Adjust display layout
- Problem: With some layouts the machine hangs! Will look into this.
- Adjust touchpad
- Switch to two-finger scrolling
- Disable mouse clicks
- Set desktop background image
- Install compizconfig-settings-manager and run ccsm:
- Assign the Resize Windows function to Alt-Button3 which is easier than the default
- Enable terminal bell:
- Install and 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 "xset b 100" to .bashrc
- Install tp-smapi module
- Install tp-smapi-dkms
- Add "tp-smapi" to /etc/modules.
- In /etc/sudoers add "Defaults timestamp_timeout=0"
- Enable fingerprint reader as I described here:
- add-apt-repository ppa:fingerprint/fprint
- apt-get install libpam-fprintd fprintd
- Run fprintd-enroll
- Edit /etc/pam.d/lightdm
- Associate my bluetooth HIDs.
- Set up hotkeys (zoom and micmute) as I described earlier
