No idea, but if it's an older Radeon with an older driver, then it might have a broken Pbuffer implementation. I seem to recall that I ran into similar problems with certain Radeon GPUs years ago. Try the following: 1. Try setting VGL_READBACK=sync in the environment on the server prior to invoking vglrun. 2. If that doesn't work, then try setting VGL_DRAWABLE=pixmap in the environment on the server prior to invoking vglrun. 3. If that doesn't work, then I don't know how to fix it. VGL is known to work well with nVidia GPUs and drivers, but AMD/ATI GPUs (particularly their consumer-grade GPUs) have traditionally been hit-and-miss. I have not tested their more recent products, though. The only AMD GPUs I have in my lab are an old Radeon HD 7660G and an older FirePro V5700. > Do you know a way to use local GPU for remote app acceleration? No matter how you attempt it, using a local GPU for remote app acceleration is going to require sending OpenGL commands and data over the network. The traditional method of doing that is using remote GLX. That is not ideal, for reasons described in the VirtualGL background article that I previously posted, but any other method of using a local GPU for remote app acceleration would have similar drawbacks. The only product I know of that might accomplish that task is NICE (now Amazon) DCV, but it is neither free nor open source. Do I know of a way to use a local GPU for remote app acceleration while running XDMCP on the remote application server? No. -- You received this message because you are subscribed to the Google Groups "VirtualGL User Discussion/Support" group.
