I run all the major linux distros as virtualbox guests so I can keep track of what's happening on planet non-gentoo, but only the ~amd64 gentoo guest machine is having this problem: When I start an X session in the gentoo guest machine, the 3D video acceleration is emulated with the "Software Rasterizer" function of mesa, as shown below: # glxinfo | grep renderer OpenGL renderer string: Software Rasterizer The problem is that "Software Rasterizer" is so slow and inefficient that the gnome3 shell specifically tests for it and refuses to start if it's found. Other guest linux distros report the "Chromium" rasterizer or maybe the "llvmpipe" rasterizer, both of which are fast enough to satisfy the gnome3 shell. So, could the problem be caused by the vbox package on my gentoo host machines? I don't know, but I can propose a test: I know some of you have access to (real) machines that run non-gentoo distros (I'm too lazy to install a non-gentoo distro on my real boxes just to debug this silly problem) and so I thought maybe you could try the same test and report back your results :) Thanks!
