I'm currently running Ubuntu 18.04 with an Asus motherboard with an Nvidia 3000 graphics chip. It was running fine in 2d but not 3d. I have a couple of Nvidia R9 380 cards, so I tried to install one on the machine. Hardware install went fine, but when I tried to get it running on Ubuntu the drivers didn't work, so I pulled it out. Now the issue is that the 3000 is not getting an associated driver. Result of lshw -c video is:
*-display UNCLAIMED

product: RS780L [Radeon 3000]
vendor: Advanced Micro Devices, Inc. [AMD/ATI]

I tried various Nvidia drivers but none are compatible, and the kernel is also not providing a driver. I've removed all Nvidia drivers but the issue remains. Any help would be greatly appreciated!
Update: I finally got the kernel driver to load:

But it seems there's still an issue with the Xsession video driver as the session is still not loading.
I've checked .xsession.errors but I'm not seeing anything there that gives me a clue:

I've also checked /var/log/messages, but no hints there.
Currently the only display manager that seems to function is lightdm and there I get the login prompt, enter my password, brief black screen and back to the login page. I've tried all the fixes I could find for the login loop issue, but none worked. It seems that the display manager can load, but then when it tries to load the X session it breaks. I've also tested with another user account on the machine with the same result. Testing with VNC the session loads fine.
Thanks in advance for any ideas.
