My system uses an Intel and AMD GPU (Radeon RX Veg M GL) the Intel one is a generic on the CPU one.

My question is that the graphics seem a little glitchy (didn't notice it in W10, was very smooth and quick) which leads me to ask cold the EOS system be using the Intel one by default?

How can I check, 1) that both have drivers installed and 2) which one is being used as system default?

Lastly, does Linux and EOS automatically update the GPU drivers if/when available?

Thanks

Using lsmod in a terminal as root will show the modules loaded and tell you they are being used. If the system is setup to use sudo then that in front of the command will give the required information. The driver (module) that is in use for the add-in card will be shown. It will be loaded and used as it is the only way you will get to see some sort of video unless the connector somehow magically jumps from it to the internal connector on the back of the machine during or before boot. You may need to install the official Radeon driver from the distributions repositories if it has not done so. It will be updated as they decide to do it in there, then once you update your system so it will be installed.

Thanks for that...it's a NUC so all "on pcb" so to speak. there's nothing to magically jump anywhere haha!

I ran that command and both show up, it doesn't actually specify which one is being used.

It is using the Radeon otherwise you would get no video signal. If there is setting in the BIOS to disable the onboard you could set that. Oh there has to be something to connect to there on the back for the built-in or it is pointless to have it if there is no way to get a signal from it.

Thanks again, Stephen. Nope, just the HDMI port for the actual video out. These NUC boxes have an architecture that is a bit different to the norm I think. The research I did at Intel was very confusing and not really illuminating at all. It says the Intel driver MUST be installed for the AMD driver to run, or rather the GPU card to work correctly.

I'll check the BIOS and see if I can disable the Intel GPU, and IF I can, what effect it has.

You are welcome. The HDMI port would be the video connector for the box. Confusing to say the least never heard of that one before needing a video driver for the not used card installed for the card in use to work. Most times it is disable the onboard so you get both the RAM back it uses and no interference with the driver for the video card in use when that driver is installed.

Yeah I hadn't really heard of it it either. For the record: these are the details from the Intel site.....

Detailed Description

Purpose

Instructions on how to download the Radeon™ RX Vega M graphics driver and software for Windows® 10 64-bit for the Intel® NUC8i7HNK and NUC8i7HVK.

This is the primary graphics driver for Windows® 10 64-bit needed to use these Intel® NUCs.

Note

Radeon™ RX Vega M graphics driver version 20.2.2 is the latest version of the graphics driver that will install on the Intel NUC8i7HNK or NUC8i7HVK.

Important note

Both the Intel HD Graphics driver and the Radeon™ RX Vega M Graphics driver should be installed. You may experience the following if both are not installed:

Unstable graphics
Can't set up multiple displays
Applications crash after opening

Well I will be damned them clowns actually did do that, simply amazing yet another way to cripple a machine with a non-standard design by Intel. I knew I had not seen it all from them but that is over the top and "OS Independent" why mention it is specifically for windows 10, are no other OSs out there. I've got no clue left on this one...

Edit: Unless it is one of them hybrid designs like they do with the Nvidia where the graphics switches between the cards depending on the load, even then still no clue as I have never set one up.

hahaha! Yep TOTALLY agree Stephen!
