| #7194 | fixed | 3D OpenGL support is not installed correctly on Arch Linux | ||
| Description |
The guest additions do not seem to be able to correctly install 3D support on Arch Linux. I tested Ubuntu 64bit and Arch x86_64 as well as Arch i686 on VirtualBox personal use binary edition and while the guest additions got correctly installed on Ubuntu with 3D support working afterwards, I had to make a few manual changes on Arch to even get it to load the correct driver. The changes that a user would have to do manually are these: ln -s /usr/lib/VBoxOGL.so /usr/lib/xorg/modules/dri/vboxvideo_dri.so ln -s /usr/lib/xorg/modules/dri /usr/lib/dri Refer to this post: https://bbs.archlinux.org/viewtopic.php?pid=547569#p547569 It would be nice if a user wouldn't have to do this manually after installing guest additions. Could be fixed by either setting the symlinks automatically or by installing the vbox video driver to the correct location to start with. I used extremetuxracer to compare the performance in both cases and to verify 3D acceleration. |

| #15183 | duplicate | 3D accel rendering -> duplicate of #12738 | ||
| Description |
Rendering bug when 3D accel enabled. Attached image shows VLC playing video in a window overlapped with File manager window. Probably not as intended. |

| #9911 | invalid | 3D acceleration becomes total deceleration on HP laptop with AMD/ATI 6770M graphics card with dynamic switching -> host driver issue | ||
| Description |
Host Config: Windows 7 64b on HP Pavilion dv6 with AMD/ATI 6770M graphics card with Dynamic switching. Guest Config: Ubuntu 11.10 The laptop's graphics card supports dynamic switching, which implies that the graphics driver can dynamically decide whether to use the generic (Intel) graphics card for power save or the AMD/ATI card for performance. AMD provides an application called Catalyst which allows user to specify which card should be used for an application. (Default card is generic.) I specified Performance card for VirtualBox application, but the graphics driver seems to allocate generic card to VirtualBox. As a result, the guest OS cannot make use of 3D acceleration (even if it is enabled from the VirtualBox GUI for that VM). Ideally, if 3D acceleration is enabled then VirtualBox should enforce usage of the performance card on the graphics driver through an ioctl like system call on Windows. The current work around from HP is to disable dynamic graphics switching from the BIOS. |
