Hi all, yesterday I did a fresh install from alien-current ISO (kernel 4.19.25) and I couldn't enter to graphics mode until I blacklisted the nouveau driver (a lost the whole day until I figure that), even worst, the PC wasn't able to reboot by himself and lock a nasty Xorg process impossible to kill with 'kill -KILL' command...

now, I don't know if you are aware of the development status of nouveau for laptops with Optimus. I'm a bit confused with all the tools around (optimus, primus, bbswitch, etc...) and the codes look very old/unmaintained. I've read all I found, but nothing works to enable/disable the Intel card (I need CUDA/OpenGL for my Ph.D. work).

I'm seriously thinking to put my hand over this, but no luck getting information/codes.

Btw, I have a 63GE MSI laptop.

Thanks in advance,

JP

I see a lot of trouble across various forums across distros with Optimus hardware. https://wiki.archlinux.org/index.php/Optimus and its links to Xrun, Prime and Bumblebee should be worth a read if you haven't already been there.

Coffee Lake is new enough, much newer than 14.2, that the Intel DDX driver package almost certainly should not be installed. Its upstream hasn't had an official release in 4 years, limited to maintenance mode. (Intel's been paying its driver writers to focus on the modesetting driver (provided in/by the Xorg server package) at least that long; the same driver that all but obsoletes the nouveau DDX driver). Could it be that ancient DDX driver(s) is/are interfering with disabling Intel gfx?

What's your output from inxi -GxxSM (from within X most preferably, hwinfo --gfxcard too if you can't)? Google's not returning very informative hits on what a 63GE actually is or contains.
