Hi Rob,

Your kernel is 4.2.0-1. So, i suppose you are in Ascii or Ceres...

If you start a X session using a display manager, the virtual console used by default will be the tty7. However, typing startx the X session should run in the first virtual console. As you know, you can jump from tty1 to tty7 typing CTRL + ALT +F7, and vice versa.

The issue, i think, is in the '/etc/X11/Xwrapper.config', provided by 'x11-common' package. Does it contain something like this:

allowed_users=console

or this other one:

allowed_users=anybody

If not, try typing:

# dpkg-reconfigure x11-common

Then choose between the following alternatives:

1- Root Only
2- Console Users Only
3- Anybody

The second and the third options will allow you to start X sessions.

Aitor.

etc/X11/Xwrapper.config is correct - allowed_users=console

Tried dpkg-reconfigure x11-common but no options appeared just returning successfully to the prompt with some errors:

update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults

[ ok ] Setting up X socket directories... /tmp/.X11-unix /tmp/.ICE-unix.

The Devuan I'm running was converted from Debian sid about 6 months ago, kernel 3.18.5.

Possibly coincidentally another program, jackd2 which was ok yesterday, refused to start this morning with a permission problem on /dev/shm. I've fixed that for now.

Googling the xorg problem earlier quite a few results involved
systemd. I only have libsystemd0 installed but I seem to remember that package was updated in the last few days. Whether that is relevant I don't know.
Trying to uninstall libsystemd0 would mean uninstalling c.800 other packages.

I'm wondering if there is some local conflict between my original Debian install and Devuan and whether it would be better to install Devuan from scratch, assuming there is a release available.

Thanks for your time.

Rob
