* Many of the special keys won't work out of the box, because [[thinkpad-acpi]] doesn't load automatically on Ubuntu 10.10. It requires [http://sourceforge.net/mailarchive/forum.php?thread_name=8d66d95c39ba6e68e2acb53ddafabcb3e401635e.1304890969.git.luto%40mit.edu&forum_name=ibm-acpi-devel this patch] which (I think) did make it into 11.04. To get it to load on boot, add "thinkpad_acpi" (using underscore) on its own line to the file /etc/modules.

* Suspend won't work out of the box on the i7 model because the USB3 driver shipped with 10.10 doesn't support suspend, and so blocks it. The fix is to [https://bugs.launchpad.net/ubuntu/+source/linux/+bug/522998 blacklist the driver], but this means your USB3 port won't work. To blacklist, create a file /etc/modprobe.d/blacklist-xhci_hcd.conf containing only the text "blacklist xhci_hcd" (note underscore). Then suspend will work. There may also be a fix which unloads the module before suspend and reloads it after; if you have got this working, update the wiki.

* The Mic hardware mute button doesn't work, and I haven't worked out how to make it do so. [https://bugs.launchpad.net/ubuntu/+source/linux/+bug/408903 Seems like this has been a problem since the first Thinkpad came out with one, a couple of years ago]. It produces keycode 248 in xev, so I guess that needs translating into a keysym and then binding to mute. One for the thinkpad_acpi team? The program "amixer" can change microphone levels and the Gnome Keyboard Settings can bind an arbitrary command to a key, so it just takes someone with a little more time than me to write a script and put the pieces together to make the button work (even if not the LED).

* The fan spends more time on than it should; there are various pages around the net commenting on this. It could be a hardware problem; one thread on some forums had an official Lenovo rep saying they are looking into it. (Sorry I can't be more specific.)

* The hardware specs claim dual microphones, but Ubuntu only sees one. I don't know if this is because they are combined at a hardware level. The Windows system can switch between using them for noise cancelling and using them for wider coverage but again, I don't know if that's software or hardware-driven.
