However... just because there's no hardware acceleration does *not* mean that 3d in AppVMs is impossible. Depending on the application, software-only 3d rendering may be sufficient. Many games (especially older and/or indie ones) are indeed still playable, and 3d cad stuff is also often usable. There are several software implementations of the OpenGL, etc. APIs, most notably llvmpipe, softpipe, and (open)swr. Search the qubes-users archives for these, and look for posts from Vít Šesták. [1] The software implementations tend to lag behind actual GPUs in terms of the subset of the OpenGL API that they actually support. More info at [2] Which renderer is used is controlled by setting envirionment variables interpreted by mesa/gallium drivers. For example, to make some games run I've had to lie about the supported OpenGL version by setting MESA_GL_VERSION_OVERRIDE and MESA_GLSL_VERSION_OVERRIDE, or switch the renderer with LIBGL_ALWAYS_SOFTWARE and GALLIUM_DRIVER. I'm not going to list any specific values here since they would quickly become out of date. Instead, refer to the documentation about these env vars at [3] and play with them yourself. You may find the glxinfo command from the glx-utils package useful to make sure your env vars are having the intended effect.
