Enabling 3D acceleration with Matrox card causes application fault after login

[air42]

Hi,

I have ubuntu-12.04.3-desktop-i386.iso 64bit LTS guest OS on a Win7 Enterprise 64bit host running VirtualBox-4.2.18-88781-Win.exe with the following hw: Dell Optiplex 7010 Intel i7-3770 @ 3.4Ghz Matrox M9128 LP PCIe x16 (driver ver 2.3.0.147) Intel(R) HD Graphics 4000

The vm was created with VirtualBox-4.2.12-84980-Win.exe on a different 64bit hardware (AMD Athlon 4450B x2 2.3 GHz, nVidia GeForce 6150 LE)

If 3D acceleration is disabled for the vm, everything works fine. If 3D acceleration is enabled, the vm boots, gets to the login screen, but immediately after login it aborts with the following application fault (copied from application event log):

Faulting application name: VirtualBox.exe, version: 4.2.18.0, time stamp: 0x5229ca20 Faulting module name: MxMGLV64.dll, version: 8.15.1.1243, time stamp: 0x50c196ea Exception code: 0xc0000005 Fault offset: 0x000000000010dc98 Faulting process id: 0x1610 Faulting application start time: 0x01cebdf6b937cd9d Faulting application path: C:\Program Files\Oracle\VirtualBox\VirtualBox.exe Faulting module path: C:\windows\system32\MxMGLV64.dll Report Id: 070db544-29ea-11e3-a58d-b8ca3a80ecfd

Please note that all my attempts to update the Matrox display driver failed so far, I suspect there is a group policy that blocks it.

The dll mentioned is part of the Matrox graphics driver.

After some experimenting, I can add the following:

• updating the Matrox graphics driver to 2.4.0.106 (most recent version) does not solve the problem
• if I do not install the guest addons, there is no problem (but here I guess I have no 3D acceleration even when it is selected)

For me it seems that there might be problems with the Matrox driver, the guest addons or both.

Please reopen if still relevant with a recent VirtualBox release.
