X1 Carbon Gen2 is the ideal portable machine.
I have dealt with laptops from asus, zareason, system76 and apple. Nothing even comes close to this thing. It is light, but not brittle, nothing feels like it is going to fall apart in four months.
Open the lid, press the power button and feel the smile spread across your face as you hear silence. If you are looking for screen real estate on the go, then this is the machine for you.
Also, the keyboard does not entirely suck.
I am not a fan of ubuntu, but it makes a great canary. If a machine will work with ubuntu, then with a little bit of elbow grease you can probably get any other distro onto it. However, if the box fails with ubuntu, then there is no way you are getting another distro to work. This is the folk wisdom and my personal experience.
Ubuntu installs perfectly and painlessly with no problems. All the hardware just works.
I was pleasantly surprised. I closed the lid, ate dinner and then came back.
When I opened the lid, nothing. It was like my beautiful new laptop turned into a drunk fratboy that didn’t want to wake up for class. Thus began my adventure down the power management rabbit hole.
The suspend duct tape.
tldr: Dont try. Change it to suspend to disk.
You are going to need more knowledge and patience than I have in order to get the x1 carbon gen 2 to suspend to ram. I changed kernels, disabled hardware, tweaked kernel params and trawled through lenovo, ubuntu and various armpits of the net to fix this thing.
The best info I found was from the kernel docs: https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt
Going through these tests was how I found out that s2disk worked.
Great! but ubuntu disables hibernate because things.. mumble… scalable…. mumble mumble…. because…
To get hibernation on lid close means ignoring all the advice out there regarding policy kit. It does NOT work.
Edit /etc/systemd/logind.conf and set HandleLidSwitch=hibernate.
While dumping to disk is NOT ideal, it is better than the alternative of power cycling evertime you close the lid.
I hope that this will be fixed soon-ish.
The suspend issue is a minor annoyance. The number of pixels that this box delivers is worth every penny.
