I'm running Ubuntu 19.10 (and using Cinnamon) on a Lenovo Thinkpad Carbon X1 Gen 7.
I installed Virtualbox, which set up an MOK password after detecting Secure Boot was enabled in my BIOS. After rebooting, I saw the blue MokManager screen, either hit enter or let it continue booting and didn't set up anything in it. Then I saw that my WiFi adapter didn't appear in the list of available network connection methods (Ethernet, Wifi, etc.). Then I uninstalled Virtualbox.
It also looks like I can't get Ubuntu to use the WiFi driver. In the screenshot for "Additional Drivers" in "Software & Updates", "Do not use the device" is selected by default for my WiFi hardware and selecting "Continue using a manually installed driver" doesn't allow me to "Apply Changes" (see screenshot) and I can't select the iwlwifi driver backport option (which I am unfamiliar with).
After disabling Secure Boot in my BIOS and via mokutil, I still see the same issue. Interestingly, the WiFi is working in a Live USB session but still not after doing a fresh install.
SecureBoot also seems to be properly disabled by checking with mokutil:
$ mokutil --sb-state
SecureBoot disabled
The following is my wifi-related dmesg output. The understanding I have from this is that Ubuntu can properly detect that my Wireless device exists and has an up to date firmware version, but isn't letting the driver be used.
$ dmesg | grep Wireless
