Solved Bhyve - how to configure Xorg in Linux guest

L

lib13

I've been trying hard to get a Linux, preferably Devuan, to work in graphical mode.
The installation runs fine, I can get access through VNC.
I can start the virtual machine and get to a console prompt for the username.
I've installed LxQT and slim.
Tried to start Xorg, got a bunch of errors.

Created a /etc/X11/xorg.conf file to include the driver "vesa".
The contents of the xorg.conf:
Code: 
# cat /etc/X11/xorg.conf

I've also remove nomodeset from /boot/grub/grub.cfg

Someone mentioned that there can be a problem using the vesa driver with UEFI.

So. To have a VNC connection to run Linux in graphical mode UEFI is needed, but vesa can have problems with UEFI.
What should be configured to have Linux running in graphical mode?
 
Use the scfb driver when using UEFI, not sure how that's named on the Linux distribution you're using but it should have something similar.
 
Thanks SirDice, but could make it.
As per suggestions in other threads, I've installed tigervnc server at the Linux virtual machine and have a remote graphical connection through it.

As bhyve still lacks some polish in the UX, the steps were:

In the Devuan Linux vm:
Code: 
# apt install tigervnc-stadalone-server
$ vncserver -depth 32 -geometry 1680x1200
enter a password, or two for a read-only session.

[check the port vncserver is running under, 5901 in my case, with
$ netstat -tulpn | grep vnc


At the FreeBSD host,
Code: 
$ ssh user@linux-vm -L 5901:127.0.0.1:5901

Then connect with vncviewer or krdc, or other, pointing to
Code: 
Then connect with [FILE]vncviewer[/FILE] or [FILE]krdc[/FILE], or other, pointing to 127.0.0.1:5901
