I'm relatively newbie to Debian and the whole "desktop and graphics" topic alltogether.
Can you tell me what kind of X server (Xorg, Wayland?) a fresh Testing installation uses with which GPU of my two ones ?
Hardware is a Lenovo Y520 entry level gaming laptop with Intel GPU + dGPU from nVidia (1050Ti).
Yesterday I made a fresh Debian install with the newest Testing installer and choosing GNOME. After 1st system boot I recognized I can run Firefox browser via right-click onto the icon on the dedicated GPU.
So it means a simple default install with no extra settings is using Optimus (Bumblebee) tech already ?
Via the nouveau driver ?
Was I on Intel GPU on the desktop while I saw the option to run Firefox on dGPU ? (then I assume yes, as a default it used Intel).
However, I heard some bad things about the nouveau driver so I went for bumblebee-nvidia .. rebooted.. and .. not sure if it worked but for the Firefox launcher the option on right click saying running Firefox on dGPU was missing.
Since then I couldn't manage to reinstall the nouveau stuff, after boot, before desktop the whole screen just blinks couple of times then freezes.
I did a new fresh install again
(Don't kill me for that pls) In general: what shall I do to bring the most out of Optimus dual GPU tech while working with factory non-free nvidia driver if I choose dGPU ? Any special commands or anything else.. ?
My goal is to use Intel GPU for everything and sometimes dGPU when needed. When I manage to get to this with nvidia proprietary drivers I hope I can retain all the good behaviour when switching to a Xen kernel and making dom0 of my fresh installation.
