Did you guys see my first post in this thread? WD (hard drive manufacturer) collaborating with RISC-V (open source cpu), so who knows?

Something tells me WD aren't planning on utilising the RISC-V ISA to get into the 'PC' CPU fabrication business .. but sure, never say never :)

You might be right! It's always about second intentions, isn't it?
At least we can hope for a pleasent side effect

Yep, expect a  LOT of updates around this .. and you'd be well advised to stay on top of them.

No problem with that. They are easily updated, both on Peppermint and on Void. My annoyance is with my daughter's Bodhi system ... Bodhi doesn't update kernels in between releases, so every two days or so I'm refreshing the packages and intalling new kernels on her laptop through Synaptic. Not difficult, just borring!

EDIT: Maybe this could actually be automated using a script to fetch the latest kernel from the Ubuntu repos instead?! Probably, worth looking into it...

I'd 'assume' that'd be doable, but I don't know enough about Bodhi to know for sure (or I'm afraid to be much help).

That was not my intention ! I don't expect to get help with another distro.
If I were to decide, she would be running Peppermint...
Anyway, just got her to the new kernel AGAIN!

Did you just install it as it or did you unload nvidia first install it and then reload nvidia ?

I installed it, as is - didn't bother compiling it, et cetera. Recognized nVidia 390.12 just fine.  ;)

Here's a link to the binaries:  https://goo.gl/wubzDQ
