New Radeon RX 560

I'm trying to install this new card. I took out the old card but it will not boot. It says it's looking for the Graphical Interface and that's as far as it gets. Should I put the old card back in with the new card and try to configure the new card with the old one in there? The old card is an NVIDIA GT 730.

Re: New Radeon RX 560

I doubt that a new graphics card is stopping the machine from booting. It is just not loading your graphical environment. Read your journal.

Re: New Radeon RX 560

I put the old card back in and it boots fine. I believe the issue is that it's looking for the NVIDIA card in order to do something with the GUI. Since it's stopping at the Graphics Interface at boot up with the Radeon card in there.

I think I need to remove all of the instances of NVIDIA in order to make the new card work. That would mean uninstalling the NVIDIA software, drivers, etc. Unfortunately, I can only have one video card in my machine as it only has one space for a video card. At install I added these packages (nvidia nvidia-utils nvidia-lts) I'm guessing I need to remove those completely from the system. I have mesa installed already what else do I need to install for this new video card?

You stop trying to boot into the graphical target and fix it from there: https://wiki.archlinux.org/title/System … _boot_into

Re: New Radeon RX 560

So you're saying I should boot into a command prompt with the new card and remove the NVIDIA drivers from there?

Re: New Radeon RX 560

Check the journal / Xorg.0.log if the system uses X.  The cause could be configuration files specifying use of the Nvidia GPU rather than just the packages being installed.

Re: New Radeon RX 560

Yes. It looks like it's loading LOTS of NVIDIA stuff. Is there an easy way to turn that all off?
I put it on pastebin.

Please also post the contents of /etc/X11/xorg.conf.  though if it was generated by nvidia-xconfig you may as well delete it.

Disable that config when not using the Nvidia card.

Disable it how? Like rename it, delete it or something?

Re: New Radeon RX 560

I would rename it for now in case you can not get the RX 560 working.  Just change the extension to something other than .conf.

OK, and that will keep all of the NVIDIA stuff from loading?
Do I have to install anything for the Radeon card to work? I heard the drivers are built into the kernel.

Re: New Radeon RX 560

The nvidia kernel module will not load without the card present.  The nvidia X module will not load without the nvidia kernel module.
There is no point in keeping the nvidia packages installed after the card is removed.  See AMDGPU#Installation for new packages may want to install.

OK, that worked. Thanks for that info. Now, my next question, Why is the Display Port monitor so grainy looking? It wasn't like that with the NVIDIA Card. Is there a way to set this Radeon card to bring up the resolution a bit. It's at 1920 x 1080 but for some reason it's not a clear picture like the VGA was using the same monitor.

Bad cable maybe?

Re: New Radeon RX 560

Possibly, incorrect DPI setting could be likely, the nvidia driver automatically sets that based on EDID, most of the open ones just default to 96: https://wiki.archlinux.org/title/Xorg#D … ze_and_DPI
