W500 this is work under progress

BIOS Issues

Linux (ie Xorg) currently lacks the support for on-the-fly switching of GPUs. It not only does not support switching, you also have to expicically turn off switching in BIOS. Go to Config->Display->Graphics Device and DISABLE OS detection of switchable graphics.

If you don't disable OS detection, linux will see two graphic adapters (try it with lspci) and will be confused on which one to use, leading to random weird side effects such as hangs and worse.

I also had to turn off AHCI in Config->SATA and used Compatibility Mode instead, otherwise the kernel would not boot occasionally.

The T9400 and up CPUs also support Intel Virtualization technologies. Just don't turn on VT-d (disk I/O virtualization) in BIOS, otherwise WLAN any a couple of other things will not work and even freeze your system, see https://qa.mandriva.com/show_bug.cgi?id=44711

Things not working/issues

As I've found most of the components are just working out of the box, I will only list the issues I have found so far:

  • Active Protection System
  • Suspend/Resume
    • while suspending works fine, resuming always ended with a blank screen, workaround below
  • muted audio not shown in alsa mixer
    • when you use the built in "mute audio" button on the ThinkPad keyboard, this is not show in any audio mixer I've tried. So if you don't hear a sound, give the "mute audio" button a try :-)
  • 3D and radeonhd
    • the radeonhd driver (still) does not support 3D acceleration

Suspend/Resume problem

If resuming just leaves you with a blank black display, try the following:

 echo "ADD_PARAMETERS='--quirk-vbe-post' > /etc/pm/config.d/w500_vbe_post

Display / Xorg

The laptop comes with switchable graphics, so you can choose on your own which GPU to use:

  • radeonhd
    • consumes the most energy
    • lack of 3D support
  • fglrx
    • changing runlevel to 3 (init 3) leaves you with X eating 100% CPU

So if battery life, DVI and 3D are important for you, you should probably use the fglrx driver, but I am fine with the radeonhd driver for now.
