I am still running Debian stable on a T460p and all I can tell you is that there is hope.
I used to have major issues with suspend and dock on this machine, with Ubuntu and then Debian. I lost many work mornings to getting the machine to show anything on the screen after docking. I tried various drivers, tweaks, everything -- sometimes it would work for a while and then trouble would be back with the next reboot or kernel upgrade.
Then one day I hit the right tweak -- or Debian flipped the right bit -- and at least for the last ~year I've had zero problems with it. Dock, undock, suspend, resume, it's 100% there and I don't even think about it anymore.
I believe it's because I finally managed to turn off the Nvidia card and use the Intel one instead, but I can't be sure. To be honest, I'm afraid to touch the video setup or reinstall Linux because I might land right back in driver hell.
