Besides obtaining a driver update from the vendor, there are several things you can do to make IDL usable again in the presence of a buggy driver:

At the time this article was written, RSI found the installation instructions for ATI and nVidia drivers to be fairly complete and straightforward.Įxelis VIS cannot control driver quality, so you may have trouble with some drivers that might be buggy. In some cases, you may need your kernel sources so that the driver kernel module can be rebuilt. Our experiences exposed no problems installing drivers on earlier versions of RedHat systems with both ATI and nVidia video hardware.Īfter downloading the driver software, follow the installation instructions correctly. The Linux distribution, version of XFree86, Linux kernel version, etc are all be important factors.
If Object Graphics rendering performance is important to you, you may wish to verify with the vendor that they support direct hardware rendering in your environment before purchasing. The best approach is to contact the vendor of your video card/chipset and obtain the latest Linux drivers, usually by visiting their website. It is even difficult to discuss minimum requirements for versions of the required software. Basically, if glxgears runs and runs fast, then IDL should as well.īecause of the large number combinations of hardware, drivers, X servers, and Linux distributions, Exelis VIS cannot publish up to date installation instructions for all situations. It is important to verify that your configuration is correct as described above before expecting to see improved performance in IDL. This should increase the number of systems that are configured to use direct OpenGL without additional configuration at installation time. One encouraging trend is that more and more components of many Linux desktops are using OpenGL for some of their graphical interfaces and applets. There may be other games and programs that use OpenGL in your Linux distribution, such as 'tuxracer' and 'chromium' that can serve as additional test cases. If the frame rate is down around 200 or less, then your system is probably not configured correctly for direct rendering or your graphics card and driver software are not working correctly.

A video card such as an ATI Radeon 9700 Pro running on a 2.8 GHz Pentium 4 will run this demo in excess of 4000 frames per second. If direct rendering is working, you should see frame rates higher than 200 or so. After a few seconds, the program will print a frame rate in your terminal window. Then your system is probably configured correctly for direct OpenGL rendering.Īs another "fun" test, run the command 'glxgears', which is often present in /usr/X11R6/bin, assuming an X installation based on XFree86. OpenGL version string: 1.4.0 NVIDIA 43.63 OpenGL renderer string: GeForce 256/AGP/SSE You will need to configure your system for direct hardware rendering as described below. Then your system is using indirect rendering. OpenGL renderer string: Mesa GLX Indirect OpenGL vendor string: VA Linux Systems, Inc Here is a quick way to determine if this is the case: Some of the more recent Linux distributions may already be configured to support direct OpenGL hardware acceleration for some of the more popular video cards. Similar architectures exist on other Unix platforms, but the internal details may vary due to the proprietary nature of these systems.ĭetermining if your system already has the required support If the hardware and software have been configured correctly, no additional action is required to allow IDL to use this faster rendering path for Object Graphics. Direct Rendering Infrastructure (DRI) or Direct hardware rendering enables IDL to communicate directly with the graphics hardware instead of sending graphics data through the X server, resulting in performance that can be tens of times faster than going through the X server. Starting with version 6.0, IDL is capable of utilizing OpenGL direct hardware rendering on Linux systems that are equipped with the appropriate hardware and software.
