Is possible hardware 2D acceleration?

[mpack]

Acceleration [2D, for Linux Guests] maybe is planning in future?

I doubt it, because AFAIK 2D acceleration is a Windows feature which hasn't been adopted in the Linux world. I.e. it isn't the VirtualBox devs you should be asking. I'm not a Linux expert, so for all I know in Linux it's included in 3D acceleration.

Incidentally, AFAIK (again), 2D acceleration means video overlays. It would have little to no effect on the speed of repaints on a desktop. If that seems slow to you then quite possibly the GAs are not installed at all: I'm not seeing a log file as evidence.

Oh, you mean that the feature (2D acceleration) doesn't even exist in the Linux world?
I didn't know that, interesting...

Without checking, I would suspect that 2D acceleration is a redirection of the DirectDraw API (to the host), just as 3D acceleration in Windows involves redirecting the Direct3D API. DirectX is a Windows tech, AFAIK it doesn't exist in Linux, which I imagine is pure OpenGL based?

@mpack
It seems that you're absolutely correct. A little bit of searching confirms your thoughts.
