My laptop (Acer Aspire E5-573g) has both the integrated graphics card from Intel (Intel HD Graphics 520) and a dedicated one from nVidia (Geforce 940M). If I install Fedora 24 on my machine, will it know by default to handle both graphics cards, or do I have to install some proprietary drivers? Also, if I have too install them, which ones? Should I install the ones from nVidia, Intel, or both?

When you install it will use the Intel one, because normally that is what the Bios define as primary (on many cases), after you install you will problably has issues as the installation will install the two drivers Intel and nvidia noveau, which will make you pc not to show graphics you will need to blacklist one of them on Kernel boot, that can be done on grub command init line or by doing ctrl+alt+f2 enter on the terminal and add a file on /etc/modprobe.d/ call blacklist and add a line like blacklist i915 where i915 is my intel module. To have two working have not read any config like that

Yeah it shows the one from intel, so should I understand that nVidia card is totally inactive? Not even consuming power?

This support should be better in recent Fedora. We actually have a test day for switchable graphics coming up in a few days, if you're interested in helping out.

The best way to find out would be to try running the Live image and see what happens. There is some support for handling both GPUs, it's called PRIME and is supported by the open-source drivers. See and . If you don't actually need to use the NVidia GPU, see if there's an option in the BIOS to turn it off. But if there isn't, I think there is support now for turning off the unused graphics chipset automatically. See for more information on that as well.
