Description

I've tried the latest release of DragonFlyBSD on my laptop, still with the same problem. When switching from X to any virtual terminal, the screen goes black and no input is bringing back the desktop or the terminal.
Also killing X doesn't help - the laptop is only accessible over SSH.

I think it has to do with drm or the intel graphic driver, but I'm no professional on these tings.

my hardware:
------------
Toshiba Portege Z30
Core i7-4500
Intel HD4000 graphic
DragonFlyBSD 4.0.5

If you need further information (logfiles, tests or anything else), please let me know!

I have the same problem with an intel card on my laptop. It originates back to DragonFly 3.6 when KMS support was added. I am interested if this promblem can be solved too.

Maybe this?

1409 Please be aware that on systems that only support syscons
1410 switching virtual terminals or exiting X
1411 results in a black screen or the last image of their desktop
1412 (like a screenshot) being presented. Commands can still be typed blindly.
1413
1414 Most, if not all, systems should be using vt(4) and this can be enabled
1415 by setting kern.vty=vt in /boot/loader.conf and reboot to activate.
