T400

Site under construction. Please help building an useful guidance!

Before Installation

Before you can start Ubuntu from CD or USB you have to change two BIOS settings:

  • Change to Internal or ATI Graphics with Config --> Display --> Graphics Device --> [Integrated graphics] or [Discrete Graphics]
  • Disable OS Detection for Switchable Graphics. Otherwise it will mysteriously switch back to Switchable Graphics.

Now you can boot you Live-CD, connect to Wireless Lan, and install the OS.

What works out of the box?

  • Wireless (Intel 5300 ABGN)
    • Only tested G mode + WEP yet
  • Intel driver for Integrated Graphics (Intel Integrated Intel GMA 4500MHD)
    • with 3D acceleration out-of-the-box
  • ATI fglrx driver for Discrete Graphics (ATI Mobility Radeon 3470 graphics)
    • To enjoy 3D acceleration, you have to install the proprietary fglrx Driver. (for example with the jockey-gtk tool)
  • Gigabit Lan
  • Touchpoint and Trackpad
    • Including scroll at the right side of the pad by default.
  • Optical drive
    • Not tested burning yet
  • Sound card
    • To use your internal microphone you have to change to HDA Intel CONEXANT Analog (ALSA) in audio-settings.
  • SD/MMC Memory card reader (Ricoh)
    • Only tested SD cards.
  • Control buttons/Hotkeys
    • Volume control buttons
    • Screen brightness control (but changing Brightness is a little bit diffuse. It's getting brighter but on maximum it changes to nearly lowest and get brighter again.)
    • Thinklight control
    • WLAN/BT/OFF toggle (Fn+F5 and mechanical toogle)
    • Media player control
  • Some ACPI features
    • Battery status, power graphs and history (tested with an single 6-Cell battery)
    • Lid states and events

What needs some Tweaks?

ThinkVantage Button

Edit the file /usr/share/hotkey-setup/ibm.hk with adding this line:

setkeycodes e017 148 #thinkpad button

You have to restart, then you can add a command with the keyboard shortcuts menu.

What doesn't work at the moment?

  • Integrated Fingerprint Reader
  • Active Protection System
    • There is no patch for Kernel 2.6.27-7 at the moment

Switchable Graphics

Suspend/Hibernate

Neither Suspend nor Hibernate work for me. They fell asleep, but waking up nearly never works. Maybe it works once... but i can't remember exactly.

Integrated Fingerprint Reader

Theres a new chipset build in, the "AuthenTec AES2810". So neither the thinkfinger nor the fprint Project support this Device at the moment.
