X freeze by switching between X and VT - results in black screen
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.

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.
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.
