Hi folks

I've been struggling to get the NVIDIA discrete GPU working my laptop. which has hybrid Intel/NVIDA graphics. Thanks to various people who have made suggestions, I have made a little progress. If I run certain graphics programs with environement variables

Code:

__NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 __GLX_VENDOR_LIBRARY_NAME=nvidia


and I see a useful increase in graphics performance.

But...

I _only_ want to use the discrete GPU for applications I select. At present, nvidia-smi tells me it is being used for Xorg. So the discrete GPU never powers down. I don't know what the implications are on a laptop, but I suspect this will trash the battery life.

How can I arrange it so that Xorg starts without using the discrete GPU? I'm guessing that something has to be done in the display manager, but I don't have a clue what.

BR, Lars.
