I can't speak to this generation of the machine, but I've had a decent experience with Ubuntu on the 3rd gen Carbon X1. I have constant issues with the wifi, though... networkmanager needs to be restarted a couple times a day or else the OS will just lose connection and say wifi is disabled. There is also a general sluggishness, especially when web-browsing, that I have not yet tracked down.

All in all, though, it is fine, and the hardware is very nice. I did have trouble getting any other distros besides Ubuntu to install and run properly, though, YMMV.

Ubuntu 16.04 installed and runs without a hitch on a 4th gen (this announcement is of the 5th gen), with the exception of the LTE (needed to install a few libraries from 16.10), and the fingerprint scanner (which is apparently at the complete mercy of the hardware manufacturer Synaptics, no ETA there afaict). One thing to be aware of, though, is that support for Hidpi screens isn't quite as good as on OS X, so sometimes you're greeted by tiny text. Steam is a notable example of an app that doesn't scale properly.

It looks like they included a different LTE chipset this time, though, so maybe compatibility is better there.

I've got a 2016 model and things work pretty well with Ubuntu 16.10. Only gripe I have is bluetooth audio isn't working out-of-the-box.

Lenovo X1 usually has good support for Linux.

I'm dual-booting Fedora 17 (with the KDE desktop) on my second generation X1 Carbon.

I don't remember having any serious trouble with any of the hardware, including the wifi (which can be a pain point). Connecting an external monitor also worked fine- I think that's another common pain point.

I couldn't find a clickpad driver that would support gestures as well as the proprietary Synaptics driver on Windows (but I tend not to use gestures anyway), and the battery seemed to drain faster on Linux than on Windows, but that's about it.

If memory serves (I've had this machine for a while) the only complain I had was that booting into grub2 was noticeably slower than booting into the Windows boot manager.

I also got the fourth generation model a couple of months ago but haven't yet installed Linux on it, mostly because I can find so little to grumble about. Either Windows is getting better or I'm getting old :)

No problem with any drivers. My blog post about arch Linux on x1 carbon: https://kozikow.com/2016/06/03/installing-and-configuring-ar...

I have a 4th gen X1 Carbon with Ubuntu and everything has worked fine. Even the functional buttons like screen brightness and volume work for me.

On the other hand, the palm detection does not work or is just terrible because I find myself constantly randomly tapping or moving the cursor when typing. Indeed it's moving around as I type this.

I ended up just disabling tap to click which I actually love using, but besides that it's great. I definitely long for the day when Linux touchpad support will match OS X's. Still, I really like the keyboard and the little nub thing is pretty awesome too, although I haven't really gotten used to using it.

I just got a 4th gen X1 and installed Ubuntu 16.10 on it. Everything's been great so far. Wifi has been working fine. The only weirdness I've noticed is a few background chrome tab crashes. Perhaps something with the gpu?

I had to make one change in the bios, to disable secure boot so Ubuntu could use certain drivers.

I've read that the fingerprint sensor on the newer X1's doesn't have linux support yet, and I've never tried the wwan stuff. That might not work either. I haven't tried bluetooth yet.

Given it's not even fully announced yet, yet alone released... that'd be a no.

I did it on the previous (4th) generation and wrote about it: https://gist.github.com/jjmalina/5e13b2269ec97895ea5fda9df6d...

Probably will be a similar experience having to install non-free wifi drivers and possibly some kernel graphics drivers not working well.

This machine isn't available yet :) But since Lenovo is the Red Hat corp laptop vendor, support is generally excellent. I've used Fedora 23+ on the Third gen X1 carbon with zero issues.

Don't have this machine, but have a Lenovo Yoga 14, I was amazed when even the touch drivers worked out of the box.

I run xubuntu 16.04 on a third generation with 0 issues. Works great.
