Good evening (evening for the ones sharing my time zone).
I’m discovering the delight of playing one Linux. CS with the native Steam software, Call of with “Play On Linux”, PES with a single wine, GTA V with Lutris…
But OK, that the price for freedom.
Everything is OK (except key or joy-pad mapping) with the 3 first solutions, but with Lutris I’ve a problem: my graphic card is not recognized by Lutris. Nor by the game launched from Lutris. So nor by GTA, meaning I can play 5 minutes before lag, 10 minute before crash.
I’m using Lutris 0.5.7.1 from an Ubuntu 20.04.1 LTS, and I’ve set up the nvidia-driver-450-server
I don’t have an integrated GPU on my CPU, but I think you should take a look at this article, the problem probably is that by default your integrated GPU is the default GPU for the X windowing system, the topic I will link too is talking about making sure that the addon/discreet GPU card is default, and the onboard GPU is not, and only used as linked through.
Maybe it is possible to tell X to use the integrated GPU on the desktop if that is what you want to save power or what ever while it is not the default, rather then the other way around to try to tell Wine to use the discreet graphics card while the onboard is default.
I tried the demurgos solution, creating 3 files (with gdm instead of sddm). Then I couldn’t log anymore on Ubuntu. I remove the files from an Ubuntu recovery session, and my computer restarted normally.
About the Bob Wya suggestion, Linux kernel boot option, I just didn’t understand it.
NB: if I launch the Nvidia X Server Settings app, the selected option is NVIDIA (Performance Mode). I’ve tried NVIDIA On-Demand without noticing any change (after restarting of course).
