A full-featured, console-based recovery tool with a focus on accessibility for visually-impaired and blind users.
We made a special effort to serve that community which is a good thing. In any case, really happy that it worked out for you. I will mark this as solved then.
]]>I've been instinctively selecting console-productivity during my installs without realizing it was bringing in braille support. After doing a re-install without it, the second VM display comes up and the system is stable.
Hope this thread will help anyone else who's encountered this issue... and now that it's resolved, I can start making even broader use of my favorite OS!
Thanks again,

]]>Being unable to run a Devuan VM under VirtualBox on a Devuan host is a severe limitation that will hamper uptake of the OS for approaches like https://www.qubes-os.org/ where the goal is to containerize user application spaces for improved security and crash recovery. I'd like to file a bug to document the issue, but don't see a link on the main site. Would the devuan-dev list be the best place to start?
Thanks again for your replies,

]]>Regardless, I seriously doubt brltty and any bluetooth/lack of bluetooth is related to preventing a display from working.
]]>The syslog, Xorg.0.log and debug logs all have a lot of Braille related messages and errors. The brltty service is also running in the process tree even though I disabled it in sysv-rc-conf.
When I enable the second monitor on the VM from Settings-Display, the last thing in Xorg.0.log is "[ 750.046] (EE) No surface to present from.". Shortly afterward, I lose mouse and keyboard control and have to forcibly power down the VM.
Is there a procedure for removing all the braille related hooks to see if this is the problem? Made the attempt to do that on Beowulf 3.0 and ended up with a hopelessly broken X. Genuinely appreciate people needing braille support, but I'd like to eliminate it completely as a potential root cause in this case.
Per your suggestions, these appear every 5 seconds from in both /var/log/debug and syslog:

]]>Dual monitors in Centos 6 and 7 VM's work perfectly with VBox 6.1 on Beowulf 3.1, but I'd like to get rid of them and have a pure Devuan stack. Does anyone know the magic for getting this to work?
Thanks,
