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
