Compilation fails on Ubuntu 18.04

From @************:
Compilation failed with
/home/ciro/git/kmscon/src/kmscon_terminal.c:105: undefined reference to `tsm_vte_get_def_attr'
on Ubuntu 18.04.
tsm_vte_get_def_attr belongs to libtsm. Have you installed libtsm first?
I had installed:
ii libtsm-dev:amd64 3-1build1 amd64 Terminal-emulator State Machine - development
ii libtsm3:amd64 3-1build1 amd64 Terminal-emulator State Machine - runtime
otherwise the ./configure was failing.
Probably libtsm.h is messed up somehow. Try run make with verbose output:
make V=1
and paste the output here.
Also, check if tsm_vte_get_def_attr is present in /usr/include/libtsm.h.
Part that looks interesting:

The file /usr/include/libtsm.h does not contain tsm_vte_get_def_attr.
I got it. The package in the official repo is rather old. You could try compile from source using my fork: Aetf/libtsm.
Thanks, that makes it compile, we can close this issue.
Then on Ubuntu, I go to Ctrl-Alt-F3 TTY and run ./kmscon, it just hangs, and I can't switch back to the graphical TTY anymore with Ctrl-Alt-F2.
I'm just a complete newbie trying to get any KMS / DRM / DRI example working to have some fun, hopefully as minimal as possible, and hopefully on QEMU Buildroot for: https://github.com/************/linux-kernel-module-cheat
Also tried https://github.com/dvdhrm/docs/blob/master/drm-howto/modeset.c on Ubuntu but it says:
drm device '/dev/dri/card0' does not support dumb buffers
as in: dvdhrm#113
