My USRP is in a "lab" hooked to a pc, but I like to ssh -Y into it from more pleasant parts of the house using my netbook. It worked great for gnuradio and most other applications until I installed NVIDIA drivers on the lab PC in order to enable cuda GPU processing. (Cuda made my processing applications much faster and I hope to integrate it with USRP output soon.) Most applications still work fine remotely, including fairly graphic-intensive ones such as Google-earth and several QT-based programs.
About that time I re-built gnuradio and now if I try to run any of the graphic sinks remotely I get the error: Xlib: extension "NV-GLX" missing on display "localhost:10.0". If I run the same application on another PC that uses the Nouveau drivers instead of the Nvidia drivers I can ssh into that PC from my netbook and everything runs fine. My guess is that the compile processes used the best available graphics on the computer it was built on even though the graphics requirements are fairly modest. I tried VNC but it's much too sluggish to use, especially for wiggly scope plots. When it works, X over ssh is almost like being directly on the machine in the messy room with the antenna drop and the noisy beige box, except I'm comfy on the couch. Is there some sort of build configure option that will not cause the executable to use the Nvidia proprietary graphics calls, but more portable ones instead? Thanks!
