#10392 fixed 3D acceleration option makes Ubuntu guest to not work correctly yurivict
Description

Once I turn 3D option on, Ubuntu 32bit guest on Mac OS 32bit host doesn't show the floating panel on the left, and doesn't show the bar on the top. Without this option it works fine.

I tried the same on FreeBSD amd64 host, Ubuntu guest with 3D option does show the panel and the bar, but screen doesn't update once erased. Without 3D option, again, it works fine on FreeBSD too.

#475 fixed 3D acceleration support for VBox guests Sander van Leeuwen
Description

This ticket is used to track development of 3d acceleration support.

I have committed my initial OpenGL guest support to the public SVN tree:

Current status:

  • communication framework between guest and host is present
  • simple OpenGL samples are functional; they display their rendered output in an external window on the host for testing purposes)
  • supported are only Windows guests combined with a Windows host
  • not all OpenGL commands are implemented; most simple ones are

Plans:

  • Linux host and guest OpenGL support
  • Add OpenGL extensions as reported by the host OS
  • Direct3D emulation using OpenGL

We are looking for external developers with an interest to help us out to complete this work.

Installation instructions:

To enable it you must add the following registry keys:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\OpenGLDrivers\VBoxOGL]
"Version"=dword:00000002
"DriverVersion"=dword:00000001
"Flags"=dword:00000001
"Dll"="VBoxOGL.dll" 

You need to build the latest additions from SVN as the OpenGL ICD mechanism needs a change in the display driver.

VBoxOGL.dll needs to be present in \Windows\System32.

TEMPORARY requirement: to enable OpenGL you must change src\VBox\Main\VMMDevInterface.cpp at line 606.

You can also directly link the OpenGL test cases with VBoxOGL.lib to test them directly.

  • replace $(PATH_SDK_W2K3DDKX86_LIB)/opengl32.lib with $(PATH_LIB)/VBoxOGL.lib in the makefile of the test cases
  • add VBOX_WITH_WGL_EXPORTS to VBoxOGL_DEFS in the VBoxOGL makefile

Enabling logging can be of invaluable help while debugging problems.

  • export the VBOX_LOG variable and set it to -all+shared_opengl+dev_vmm_backdoor
  • build the debug version of VBox

The full debug version of VBox adds quite a bit of overhead and might assert from time to time. For OpenGL debugging you only need to use the debug binaries of the hardware Devices (VBoxDD*.*). You can simply copy them into the directory with the full release version. (both must be at the same SVN level of course)

#8854 obsolete 3D accelerator issues Robert Schmitz
Description

I am having problems with the graphics pre-processor in Salome-Meca-2011.1 and have found that the problem lies with the 3D accelerator in Guest Additions (v4.0.6). This program is part of a finite element program. The main window where one would work on a model disconnects from the program and the program freezes up. The error or warning message that shows up in the terminal window is: OpenGL Warning: No pincher, please call crStateSetCurrentPointers() in your SPU. There have been other posts where folks working with graphics programs such as AutoCad have experienced similar problems. The only solution at this point appears to be to deselect the 3D accelerator box in Display in the VBox Manager. I have the following hardware and software in use when running this program: AMD Turion II Dual-core Mobile M500 (1 core used under VirtualBox)

ATI Mobility Radeon HD 4200 graphics card, v8.632.1.2000 driver (128MB memory used under VirtualBox and 3D acceleration presently disabled)

4GB Memory (1600MB memory used under VirtualBox)

Software:

Windows 7 professional, 64bit.

Oracle VirtualBox, v4.0.6, 64bit

Linux Ubuntu 10.10, 64bit

Salome-Meca 2011.2 and Code-Aster STA10.3, uses Salome 5.1.5

Hope this helps with finding a solution. Thanks.
