[Pkg-virtualbox-devel] Bug#703239: [Patch proposed] further information

[Francesco Presel]

I enabled 3d acceleration; here's the (partial) output of glxgears and 
glxinfo. Glxgears is a bit slow, but that's quite usual on VB (I think), 
and might depend on hardware too. Anyway, things appear to work as 
expected, in my case.

In reply to #55, I did not experience such problems. I'm running Debian 
Wheezy x86 as guest, and Linux Mint Debian Edition (with Wheezy 
repositories, but with the latest version of VB, directly from their own 
repo) as host. Resizing both the window in the host and the screen 
inside the guest had the expected behaviour, ie everything resized 
correctly. Even transparent mode worked. I sometimes needed to wait some 
seconds before the resize occurred, but after a few seconds everything 
was OK.
Anyway, is that related to Debian, or is it a problem with VBox itself? 
Could it depend on the host instead?
If one of the proposed solutions (defining RHEL somewhere, or changing 
the kernel version in #IF_s, or any similar and more elegant solution) 
really allows to compile and run the modules, perhaps the problems with 
rescaling are a different (and less grave - perhaps not RC any more) bug?

270 frames in 5.0 seconds = 53.976 FPS
262 frames in 5.0 seconds = 52.115 FPS
206 frames in 5.0 seconds = 41.156 FPS
139 frames in 5.0 seconds = 27.720 FPS
