I installed on my notebook HP 15-r208nl elementary OS Juno. My pc has a graphics card dedicated to nvidia geforce 820m and a dedicated video card intel hd 5550. Currently the PC uses the integrated one but I would like to set the dedicated one as primary because when I watch videos with a higher resolution, they stop. Giving the following command: Code (Text): lspci | egrep 'VGA|3D' the result is as follows: Code (Text): 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09) 09:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M] (rev a1) From here I see that the dedicated nvidia video card is set as a 3D controller. How can I set it as primary? PS: I tried a lot of guides to install nvidia drivers, etc., but I could not get any results. You grow in advance.
