Does the X1E support S3 sleep under Linux? It can't wake from suspend in Ubuntu Linux 18.10. Do we have to wait for Lenovo to offer such support through a BIOS update (like the X1C6) before wake from suspend or hibernate is possible under Linux?

I realize this is an old thread but... did you ever resolve this issue?
I'm struggling with this issue as well (which you can read more about on this forum and the pop_os sub reddit).
In answer to your question about S3, yes it does appear to support it. In the terminal, enter: dmesg | grep -i acpi | grep supports
...and you should see that S0 S3 S4 S5 are listed.
Poking around in /var/log/syslog might give you some idea (although it has not for me) as to what the culprit is as well.

I asked our Ubuntu expert (who happens to have X1 Extreme sitting on his desk) and he's unaware of any sleep problems with Ubuntu 18.10. S3 is the only sleep mode on this system (it doesn't support modern standby like X1 Carbon).
Edit: what are you doing to suspend the system? Close the lid? Or something else?

Yes, close the lid, click suspend, and or let it go to sleep on its own.
The irritating thing is that it works for a time (several days) and then all of a sudden goes back to a black screen upon wake for a few days.
I' running Pop_OS 18.10 (which is a slightly fancied up version of Ubuntu 18.10).
Do a Google search and you will see that a lot of folks are having the exact same problem--and a lot are having no problem whatsoever. :/

I have not seen an issue with the below configuration
nvidia driver version 410.78, Graphics card is the GTX 1050 Ti, Display in Bios is set to Hybrid mode.

Well,... that is what I am running and it only works intermittently.
For a time I thought TLP (which is, aside for system updates, the only other thing I have installed) might be the culprit but I took it off and ran it for a week only to see no change.
