I just got a CHOETECH USB-C to HDMI adapter. Plugged it into a Lenovo X270 laptop running Ubuntu 18.04 and it just worked. Zero configuration required.
I did research last year for the most popular Thunderbolt to HDMI adapter I could find. Like some users my first adapter did not plug in tightly and signal could shutoff on it's own. The Vendor actually reached out to me before I could complain with a customer satisfaction survey. I told them the problem and a new one arrived in a few days and I'm still using it.
(I don't have enough reputation to comment, so I'm posting this as an answer.)
I can confirm that the choetech adapter seems to work. My model looks a bit different than the others linked in this thread (maybe because I'm in Germany), but it works fine as well. This is the model I purchased: https://www.amazon.de/gp/product/B07F6WD1J7
I tried an ivanky usb c to hdmi cable first (https://www.amazon.com/dp/B07NPHK6LR), but it didn't work reliably. It took a long time (sometimes up to 3 minutes) until the display shows something again after waking up from standby.

I am using Club 3D CAC-1504 USB-C to HDMI 2.0.
Some laptops have DisplayPort over USB-C(Latitude 5590, i5 8250u, no discrete GPU) and the above adapter works with LG 32UD59-B.
Other laptops have USB-C only for data transfer(no DisplayPort, no Thunderbolt3) and the adapter will not work.
bought this one on Amazon.es ( i live in Portugal ) and worked fine, plug and play! I have ubuntu 20.04 LTS.
