I’ve had more success with bbswitch and bumblebee, however I have tried many of the other options and configurations with limited success. Maybe it is time to look back at this or just leave well enough as is.
I also had some success with a separate 1 configuration that let me run only on the dedicated GPU (dGPU), but with such an old computer designed to use the dGPU as a secondary option, it seemed overkill.
Finally, there has been an occasional, rare need to write to /proc into the path of my dGPU in case things get a bit messy, but that was rare between some updates or changes.
Yup lots of options, even things far advanced like SyncThing that can safely keep things in sync between many devices and locations without having to think about it. Anyways, this is a Reddit post to see what people are using, while I wrote my own setup using rsync and dm-crypt.
