(e.g. the MSI PS63) [on Ubuntu 19.04] Is it possible to use the Nvidia GPU for only some applications? I think this should work with DRI Prime (Nvidia Prime). Am I right? If I launch an application with it (or the rightclick -> launch using dedicated graphics card option from Gnome) it enables the Nvidia dGPU and after closing this applications the Nvidia card is automaticly disabled (for a longer batterylife)? Do I have to reboot my computer or to logout & login? How about external screens? Do they work (when they are connected to the Nvidia card)? Thank you very much!
