Autodesk Composite Hardware Certification FAQ

1. Where can I find pre-2012 certification results?

You can find certification results for prior for prior releases of Autodesk Compositeto 2012 at the Composite Certified Hardware link.

2. Does Autodesk use dual monitors in the Composite graphics hardware certification process?

Certification was performed on dual screen at a resolution of 1920x1200(60Hz). On NVIDIA® cards, select: "Dual view" mode (under set up multiple display), and on AMD® make sure to select "Extended" for your Dual screen setup.

3. What version of Mac OS X does Autodesk use in the Composite graphics certification process?

Composite 2012 graphics certification testing was done using Mac OS® X v.10.6.6 unless otherwise specified. Autodesk recommends that you use the same operating system version that was tested with the graphics hardware. A newer version does not always provide the best support.

4. How can I tell what version of Mac OS X my system is running?

To find out what version of Mac OS X is installed on your system, select "About This Mac" in the Apple menu. The general operating system version number is just below the logo; for example: Version 10.5.8.

To find the build number for that version, click Version. The version number will display the build number; for example, build 9L30. (You may need to refer to the Apple Support site to identify your system.)

Note:  Occasionally, Apple releases slightly different versions that have the same version number, but display different build numbers. These slightly different versions may behave differently. You may need to determine the build number in order to correctly identify the OS version.

5. Are Intel integrated graphics systems Recommended or Certified for use with Composite 2012?

At this time, Autodesk does not conduct graphics certification testing on Apple® computers with integrated Intel® graphics hardware. As a result, these integrated graphics systems are not Recommended or Certified.

6. Are custom Mac OS X vendor drivers Recommended or Certified for use with Composite 2012?

At this time, Autodesk conducts graphics certification testing only with the official Apple default drivers that are included with the particular version of the Mac OS (for example: 10.6.6). Drivers acquired by any other means, such as directly from a graphics vendor, have not been tested and therefore are not Recommended or Certified.

7. How do I tell which driver is installed on my Mac OS X system?

To verify the video driver version installed on your Mac OS X system, open a Finder window and navigate to /System/Library/Extensions/(vendor extension file). With this file selected, Ctrl-click to select Get Info to view the version information.

For example, to identify the version of the video driver installed for the NVIDIA GeForce FX 8800 Ultra, select the /System/Library/Extensions/NVDANV50Hals.kext file and then Ctrl-click and select Get Info.

8. What version of Linux does Autodesk use in the Composite graphics certification process?

Autodesk Composite 2012 graphics certification testing was performed using the following Fedora® Core and Red Hat® versions:

Fedora CoreRedHat
14 – 64bit OS5.5 – 64bit OS
Kernel Version
2.6.35.11-83.fc14.x86_64 
Xorg Version
1.9.4-1.fc14.x86_64 
Glibc Version
2.13-1.x86_64 

9. Are there any Kernel limitation or caveats with Composite?

Fedora 14 ships with the "Nouveau" driver enabled by default. When this driver is loaded, the NVIDIA driver is prevented from loading. Consult your distribution's documentation on how to disable the Nouveau driver before you install the NVIDIA driver.

10. Are any other Linux flavors compatible with Autodesk Composite 2012?

The Linux® operating system is extremely flexible when it comes to precise versioning of different components, drivers, and libraries. Composite may behave very differently on superficially similar systems and Autodesk cannot always explain or determine the cause of a problem.

Internally at Autodesk we have stabilized using certain Linux configurations. To see a list of these configurations, visit the Find Graphics Hardware page and select Autodesk Composite in the “Your Products” field. Then use the “Your Operating System” dropdown to view the list of Linux configurations. This list is provided to help our customers, but we make no guarantees as to the reliability, stability, or availability of these components. This is not a complete list of Linux configurations choices. This list includes important components that significantly affect the Composite software.

Due to the many operating system and architecture differences between the supported platforms, the results of some operations will differ on different platforms. This problem is noticeable in results of iterative operations and leads to cumulatively large differences, for example, dynamics, and some rendering. You may not be able to "mix and match" renderings on different platforms.

We do not recommend saving data directly from Composite to NFS or other remote mounted file systems. We strongly recommend that you save the files locally and then copy the data to the mounted storage system.

When texture images are stored on systems remote from the rendering process, depending on network speed, specifications and load, the renderer may be unable to access a texture file on demand and 'drop' individual textures on a frame by frame basis. To avoid this, store textures on a system local to the rendering process.

Composite is not linked to be compatible with SELinux. If SELinux does not need to be enabled, it is recommended not to enable it. The SELinux requirement may be addressed via two mechanisms after Composite has been installed.

If you do not wish to use SELinux enforcement, disable it by running the `setenforce 0` command before starting X, or by adding selinux=0 to the end of the kernel line in /etc/grub.conf or change /etc/selinux/config and reboot. You can change the security context of the Composite libraries with the chcon command, but this has not been tested.

KDE klipper is known to have focusing issues with Composite that may contribute to application instability. We recommend removing the applet from the panel and editing the config file, (~/.kde/share/config/klipperrcv), to disable KDE klipper. [$Version] update_info=klipperrc.upd:25082001,klipperrc.upd:kde3.1 ral]

AutoStart=false

11. Are there any specifics about OpenGL visuals?

The Composite choice of OpenGL® visuals is a RGBA 8/8/8/8 double buffer with depth buffer of 24 (where applicable). Visuals available from the XServer can be found using the command glxinfo.

If Composite cannot obtain a preferred visual, it will use a lower value as a fall-back if possible. If this happens, a warning is issued.

Set up the XServer so it uses direct rendering to get as many visuals as possible. Use a depth setting of 24  to enable 8 bits per component.

12. What version of Window Manager does Autodesk use in the Composite graphics certification process for Linux?

Composite 2012 graphics certification testing was done using Gnome 2.16.0 for Red Hat 5.5 and Gnome 2.32.0 on Fedora Core 14. Other window managers are likely to work acceptably, but because they have not been tested they cannot be listed as Recommended or Certified.

13. What if I am using Recommended or Certified graphics hardware and still have issues?

If you are experiencing display issues not described in this FAQ, please switch to single screen at resolution of 1920x1200 (60Hz). You can also visit our Knowledge Base or contact customer support.

14. How can I contact Autodesk’s Hardware Certification group to report a problem with Recommended or Certified graphics hardware?

To report problems directly to the Hardware Certification group, use the Report a Problem form.
