Yes it is. With a default xorg.conf file I cat use a monitor and mange X-server. ghopper@miner:~$ ps -ef|grep X root 1082 1080 0 13:25 tty1 00:00:00 /usr/lib/xorg/Xorg vt1 -displayfd 3 -auth /run/user/127/gdm/Xauthority -background none -noreset -keeptty -verbose 3 ghopper 1571 1557 0 14:25 pts/0 00:00:00 grep --color=auto X

I have a headless (there isn't monitor at all) test rig for crypto mining with two graphic cards on it (GTX1060). It worked fine until update to release 17.10.

Yes it is. With a default xorg.conf file I cat use a monitor and mange X-server. ghopper@miner:~$ ps -ef|grep X root 1082 1080 0 13:25 tty1 00:00:00 /usr/lib/xorg/Xorg vt1 -displayfd 3 -auth /run/user/127/gdm/Xauthority -background none -noreset -keeptty -verbose 3 ghopper 1571 1557 0 14:25 pts/0 00:00:00 grep --color=auto X

Try this before running it

xhost +local:

The xhost program is used to add and delete host names or user names to the list allowed to make connections to the X server. The local family specifies all the local connections.
