Re: [VirtualGL-Users] vglrun not working on FreeBSD
Hmm, looks like my driver does not support pbuffers, so I will get an nVidia as you recommended.

Sorry, this message got spam-filtered, so I didn't see the full content of it. ATI adapters should work fine with VirtualGL provided that you install the ATI Catalyst driver. Please give that a try: http://www2.ati.com/drivers/linux/ati-driver-installer-9-3-x86.x86_64.run I misunderstood and didn't realize you had an ATI board. The easiest way to test VirtualGL is to just log into the machine locally and run: export VGL_LOGO=1 vglrun /opt/VirtualGL/bin/glxspheres Assuming the application launches properly, you should see a VGL logo in the bottom corner of the window, which lets you verify that VirtualGL is in fact active and that the app is using it rather than displaying directly to the X server. Once it works locally, then the next step is to go through the procedure in the User's Guide for configuring gdm or kdm so that VGL can access the 3D X server when it's sitting at the login prompt. Then you can test the same thing remotely. Then, and only then, should you try running VirtualBox in VirtualGL. -- Keep Your Developer Skills Current with LearnDevNow!

Sorry for my momentary confusion. export VGL_LOGO=1 vglrun /opt/VirtualGL/bin/glxspheres Thanks, I will try this when I get home and let you know. I meant to try it once you know that you have Pbuffers working. There's no way it will work until glxinfo shows Pbuffer-enabled FB configs. So yeah, I guess buy an nVidia board, since they seem to have the only Pbuffer-enabled FreeBSD driver support. -- Keep Your Developer Skills Current with LearnDevNow!
