11905,glXChooseFBConfig Fails for Choosing Depth Buffering (0xc) (Linux Guest),Geometrian,,"In some OpenGL programs on Linux guests, glXChooseFBConfig will fail:

OpenGL Warning: glXChooseFBConfig returning NULL, due to attrib=0xc, next=0x18

Attribute 0xc is ""GLX_DEPTH_SIZE"", and removing this record from the list of attributes passed to glXChooseFBConfig alleviates that problem, but of course does not allow one to choose a depth buffer.

Searches revealed that this problem occurs in conjunction with VirtualBox, though I seem to be first to notice the correlation.  My test environment is a Windows 7 Professional x86-64 hosting a Ubuntu 12.04 x86-64 guest.  The host has updated graphics drivers.  The guest does not report any proprietary drivers, but the guest additions are installed and 3D acceleration is enabled.",defect,closed,3D support,VirtualBox 4.2.14,fixed,"OpenGL, X11",,Linux,Windows
