Ubuntu: Lenovo T560 / T460 hardware compatibility



Question:

I see there is a certified T550 install, however did anybody try T560 or T460 yet? Can Ubuntu use an integrated GPU & sound card? And how about my Camera, Microphone, etc? If anyone has some insight, I would appreciate any feedback.


Solution:1

I installed Ubuntu 15.10 on a Lenovo Thinkpad T460, and then upgraded it to 16.04. I've been using it for a few weeks, and these are the only problems I've hit:

  • When I upgraded from 15.10 to 16.04, Ubuntu started hanging whenever I move my mouse cursor off the HDMI external monitor onto the primary display. If I permanently remove the external monitor, then it everything is fine. This bug can be fixed if you manually upgrade to a newer kernel. This isn't as scary as it sounds, just a bunch of wgets then a "dpgk -i": http://linuxdaddy.com/blog/install-kernel-4-4-on-ubuntu/. Be sure to follow the correct 32 or 64 bit instructions on that page! More about this bug here Laptop freezes after connecting external monitor, since 16.04 update and here https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1559308.

  • The audio is sometimes slightly crackly, as if overloaded. It especially emits a crackle when the login screen displays and makes its quick bongo noise, as if the audio system has just been activated and isn't quite ready for business. I haven't noticed any problems while playing music though.

  • Twice in the month or so I've been using it, the wifi device has disappeared from Ubuntu's knowledge. Each time, after a few reboots, it reappeared again. Otherwise it's been rock solid. Who knows whether this is software or my hardware?

  • On 15.10, there was a bug which prevented long presses or drags when using the physical buttons of the trackpad. This has been fixed in the latest 16.04 updates (and maybe in 15.10 too, I don't know.)

  • Closing the lid would hang instead of suspend, but this problem has been fixed now.


Solution:2

I tried Lenovo T460 with Ubuntu 14.04 LTS, 15.10, and 16.04 Beta 2 and they all had two issues:

  1. Using an external monitor would freeze the system. (I tried many combinations, e.g. plug-in then turn on, plug-in at login screen, different cables, etc)
  2. Closing the lid would cause the system to freeze and not go to sleep.

After updating to linux kernel 4.5 you can attach an HDMI monitor, but mini Display Port (mDP) will still cause the system to freeze, and closing the lid still causes the system to freeze.

For more details, see my comment on the "Official T460s Ubuntu support" ticket.
