T450 owner here, running Ubuntu 16.04 LTS Desktop. My machine hangs when I unplug it from the Thinkpad dock. X rendering glitches are an hourly occurrence and X crashes weekly. In laptop mode, the trackpad handling is not up to snuff either. (I guess if I wanted all those features, I could just install Windows.)

You will most definitely want a recent kernel (16.04 ships with 4.4 - you want 4.8 or later). Also check the Arch wiki about Intel video to see if you can fix your problems with X (https://wiki.archlinux.org/index.php/Intel_graphics), eg. switching from SNA to UXA.

Thanks for the link -- I'm still hanging when unplugging from the dock, but switching to UXA and disabling 3D accel seems to have quieted the glitches down.

I did try some newer kernels a few months ago, but then my wifi stopped working. But this should not be necessary when running a flagship LTS desktop Linux on extremely common hardware from two years ago! I expected more.

Linux hardware support often takes years to mature -- for example, the graphics hardware on my Haswell laptop has seen steady improvements despite being years old. I would strongly recommend against using a LTS linux release from around the time your computer was released. Its just going to be too old. Try Ubuntu 17.04, or take the jump and just use Arch. I use Arch on all my work and home machines, without issue. Maybe twice a year requires 5-10 minutes of extra work during an upgrade to ensure a package update works.

No point in doing that. Just use the hardware enablement stack. It gets you the 17.04 kernel/X/etc over the LTS base. Best of both worlds.

I'd never heard of the Hardware Enablement Stack. I am going to try this when I get near my Thinkpad, thanks!

For what it's worth, I tried a few different OSes, including Ubuntu 16.10 (which was the latest at the time), before settling on 16.04 LTS (which was released a year after the laptop came out). I plan to try 17.04 when I get some time, but I also expect to be disappointed. I got about 10min into an Arch install before laughing myself into a coma -- I've seen smoother Unix installs from the 1990s.

But I will reiterate: this is clown shoes. Expecting this kind of effort from desktop users is hostile.

I'll agree the the Arch installer could be better, but its not difficult, especially having done it a few times. The install starts pretty barebones and then you add on what you need - annoying if you want a 1-click to fully setup GNOME (or whatever) desktop, but perfect for people like me. You also get the benefit of learning how all the parts of a working Linux desktop come together.

Personally I find all-in-one installers annoying. I find I have to spend a ton of time removing crap I don't want and replacing it with what I do want. It would take me probably as much time or more to install and configure Ubuntu as Arch would.

You might want to check out Fedora too -- I hear the latest release is pretty great. Arch based distributions like Antergos or Manjaro might be good to check out if your only hangup with Arch is the arcane installer.

Re: the X issues... dump the Intel X driver for the modesetting driver (you will want a recent kernel for this). Made a world of difference on my Intel laptop.
