[DragonFlyBSD - Bug #2808] X freeze by switching between X and VT - results in black screen

Issue #2808 has been updated by shamaz.


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.

----------------------------------------
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!
