Recently I had to switch back to my x200 and found that it wouldn't
suspend anymore, and I wasn't sure why. Then I somehow screwed up my
system and had to do a reinstall of guix and suspend worked again. I
wasn't sure why... now I seem to have the answer. When I reinstalled, I
must not have done so from the latest guix versions.
cwebber@jasmine:~$ uname -a
Linux jasmine 4.17.3-gnu #1 SMP 1 x86_64 GNU/Linux
So I guess if I did a system upgrade, I would have the problem again :)
Note that I am running this x200 with a (somewhat out of date) Libreboot
install.
