Current- Nvidia Optimus - Use Dedicated Card
by pr0xibus from LinuxQuestions.org on (#5DZVS)
Evening folks
I have an HP Omen Laptop with the Intel GPU and a GTX 1050, for a while I was happy with having to use prime_render_offload to run an application that required me to use the dedicated card, to be honest I wasnt going to change it until today.
I have another HP Omen, and just on the off change I wanted to have a look at Fedora (something I am contemplating putting on the kids computers).
Anyway after installing Fedora, and installing the Nvidia drivers, I noticed a section "enable NVIDIA GPU of an Optimus-based laptop all the time" I couldn't see a section on the Slackware Documentation for this, so decided to just copy over the /etc/X11/xorg.conf.d/xorg.conf to slackware, surprised as the xorg was very different, it worked.

Apart from power saving is there any other benefit to using the Optimus technology? The intel GPU was more than capable for what I was doing, general Computer usage and some light gaming on steam
Using the Nvidia card to render everything I assume will free up the CPU to a certain extent?
