Everything worked perfectlyand there was an Nvidia tool with a gui installed so that you could tunethe settings AND "disable" the Intel gpu (presumably to save power).(I do not know what this means exactly given the possibly complicatednature of the hardware connections).Does the RPMfusion Nvidia driver not come with such a tool.If it does you might be able to tune the Nvidia to do the things (CUDA) you want.
