Comment 16 for bug 1310489

I agree that this bug should be a higher priority. I have a cluster built on Quad CPU SuperMicro H8QME2 motherboards with hex-core Opteron CPUs . With 12.04LTS, the motherboard ATI graphics worked fine as the machines are BOINC number crunchers. The motherboards also have NVIDIA Telsa GPU co-processor boards for GPU number crunching, which I have not been able to get working for several weeks since upgrading to 14.04LTS. They all worked fine with 12.04 LTS, but this "new feature" of 14.04 LTS is absurd.

I could not figure out what was happening the xorg.conf files. I have to load the NVIVIDA drivers for CUDA/OPENCL processing to work, but needed the display to be active on the motherboard ATI graphics , as these Telsa cards are strictly for crunching and have no display output capability. This "new feature" kept forcing the systems to try to display to a screen attached to the TESLA cards.

If the problem can't be fixed easily, an simple work-around for users should be provided until the problem can be fixed.
