Arc B580 issues on Pop OS

[mike_v]

I just purchased an Arc B580, thinking it would be fun to have a second machine to mess around with Linux and see how well games work with a decent video card on Linux. 

I have an old-ish Asus Z390 Pro4 motherboard with an Intel Core i5-9400F. I was running Windows 11 on the machine with an nvidia 980, but I swapped the 980 for the B580, installed Pop!_OS, and have been trying to make it work consistently. I'm having a couple of problems:

Whenever the machine restarts, whether or not the machine will display anything is a crapshoot. Sometimes bios information will display for a second or two and then the screen will go black (but everything indicates the machine is running because USB devices are still lit and all fans and whatnot in the case are spinning), and sometimes it will display correctly and I can login. I'm very confident this isn't a problem with any of the cables or monitors or anything, because 1) sometimes it will work and I can use the machine without issue, and 2) I've tried swapping the B580 for the old 980, and I don't have any of these issues when the 980 is in there. 

I followed instructions for installing drivers for the GPU (https://dgpu-docs.intel.com/driver/client/overview.html) without issue, but when I get to this command:

clinfo | grep "Device Name"

I don't get any useful info. All I get is:

WARNING: Small BAR detected for device 0000:03::00.0

Finally, I turned on more extensive Steam overlay information (FPS, CPU usage, GPU usage), and when running a game, the GPU usage remains at zero. 

Based on all this, I would guess the GPU is installed incorrectly or something, but since my CPU is an F series, I can't even display anything without a GPU - if I try to connect an HDMI cable directly to the motherboard, it doesn't do anything. 

So yeah, I don't know what to do at this point. I originally thought it was an issue between the motherboard and GPU, but everything works 25%-ish of the time. 

Thank you for any help you can provide. I can provide more information if necessary.

You may want to review the requirements for arc:

@Fahadali   Read the arc requirements.  The Z390 is not supported/not compatible.

Thanks for the help, guys. You pointed me in the right direction - I wasn't aware of the resizable BAR thing. I followed the instruction here (https://www.asrock.com/support/faq.asp?id=498), and while this seems to have drastically cut down on the number of times the computer would restart and not display anything, it doesn't seem like the GPU is actually doing anything if I launch a game. I've realized that, even if I was able to get this working, it would probably only buy me a couple of years since this motherboard and CPU are each 6+ years old, so I should just do something else with the GPU. 

Thanks again.
