Steps to change from Nvidia to AMD GPU

General system Kernel, boot, graphics & hardware
1

Hi there,

I’d be grateful if someone could check my plan for this update

I’ve got an RX6000 arriving tomorrow.

I’ve done some research and plan to:

uninstall nvidia-dkms and nvidia settings

remove /etc/X11/xorg.conf (this was created by Nvidia settings I believe)
remove /etc/x11/xorg.d/20-nvidia.conf

Install xf86-video-amdgpu
Install lib32-mesa vulkan-radeon lib32-vulkan-radeon vulkan-icd-loader lib32-vulkan-icd-loader (some of these are already installed)

Shut down, swap cards and keep fingers crossed

is there anything I’ve missed or that’s just plain wrong??

Thank you

I think that’s what i would do. What is in xorg file? I didn’t think this was created by Nvidia or should have been removed by it?

cat /etc/X11/xorg.conf | eos-sendlog

Thanks,

xorg.conf mentions nvidia and not much else, so guessed it best to remove

This was most likely created by Nvidia settings so yes.

Thanks,

hopefully I wont have to bother you all tomorrow with a blank screen issue :grin:

I’ll let you know how it goes either way

Thanks again

What card did you actually get?

Its a PowerColor RX 6600 Fighter

Vaguely affordable and has a 0db fan mode.

I’m not big into gaming, but needed 2 Displayport ports and using wayland would be good too

8

What does that mean?

9

fan turns completely off (i.e silent) below a certain temperature.

10

Oh okay. I have an RX 590 Gigabyte and it has a fan stop mode. It lights up when the fans stop. They don’t stay off long though. It is intermittent. My other Nvidia GTX 1060 i have never seen the fans even run? I almost wonder if it doesn’t get hot enough? They aren’t supposed to come on until it reaches a certain temp. :man_shrugging:

Edit: Not a gamer either.

Project temporarily aborted.

8-pin GPU PSU connector not compatible - need adapter :frowning:

12

What does the power supply leads give you?

Edit: Is it only a 4 pin and you need 8

13

Its an old (but good) seasonic PSU. It has, what I thought, was an 8-pin GPU connector, but the ‘shapes’ of the individual connectors don’t match. I don’t think it wise to force it in!!

14

You would think it would be universal. There is an 8 pin CPU plug for power that goes into the board and their are 8 pin GPU power that are for graphics. They are definitely different.

15

Yes, I checked the 8-pin CPU plug. That is a different layout again (and wouldn’t fit the GPU)

Thanks

Well if you have a couple options 12 volt molex to 8 pin Gpu. Or Sata to 8 pin Gpu if it has those plugs.

Thanks,

Yes I’ve ordered the 12 volt molex to 8 pin Gpu cable

should be here in a couple of days.

At least I got the nvidia back up and running without any grief :slight_smile:

I swapped from NVIDIA to AMD 2 years ago and what I did was install mesa and xf86-video-amdgpu and uninstall all NVIDIA related packages. Then I swapped the cards. It’s very easy and works out of the box.

Since it is a recent card, make sure you have the latest kernel. I have seen someone unable to get his 6700 XT working at launch because their kernel were not up to date.

Thanks,

but don’t worry - I’m an update-a-holic :slight_smile:

just be careful with some of these connectors. They like to make them shotty at best sometimes which can become a fire hazard fairly quickly. There is also the issue of if the molex/sata on the PSU are really up to the task or not
