In tools system devices I checked the two boxes that are associated with graphics and audio on my graphics card. Then I clicked the button on the bottom hoping it would break up the iommu group they are both in. Next I rebooted to save changes and got stuck on 'vf io-pci 0000:01:00.0: vgaarb: changed VGA decodes: old decodes=io+mem,decodes=ii+mem:owns=io+mem' I am assuming that it is getting stuck because breaking up two devices that are on the same physical device is not possible.
I do not have a backup of my USB drive.
Is it possible to edit something on the USB drive and reverse the changes that I made or is the change on a hard drive?
I'm not sure what to do. Please help.
Thank you in advance.
