Ubuntu is unable to detect my GPU

[enon97]

Hello,

I have an MSI laptop which was working fine with Ubuntu 18, but I decided to upgrade. It has one of these dual graphics setups, which and Intel HD 630 and a NVIDIA GTX 1060 6GB. On Ubuntu 18, I simply get the NVIDIA GPU to work by selecting its drivers on the "Additional Drivers" tab under "Software and Updates", but on this version of Ubuntu, my GPU doesn't appear there any more.

Also, if I type this in the console: $ lspci | grep -i --color 'vga\|3d\|2d'

This is the only line I get:
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 630 (rev 04)

Just in case, my laptop model is this: https://es.msi.com/Laptop/GL72VR-7RFX

Any help would be appreciated.

Thanks.

Edit: I forgot to say that I also have Windows on dual boot and the GPU works perfectly fine there. Also, it is not disabled on the BIOS or something like that. I don't think that is even possible on my BIOS either.

This same thing happened to me. Except that I was on Ubuntu 19.10 and working perfectly fine. I could either enable the nvidia card or disable it and use just the intel built-in and both worked fine. Now, like you, on Ubuntu 20.04 the nvidia card does not even show up with lspci or lshw. It's just plain missing. And, like you, I can dual boot and the nvidia card is found in Windows and works perfectly fine. It's a problem in Ubuntu 20.04 but I don't know why. I've tried disabling secure boot, makes no difference. I've tried installing the 5.6 linux kernel found in the official ubuntu source. That doesn't fix it either. What's strange is that this doesn't seem to be a widely reported problem but a whole lot of people must be running into it - unless we're both doing something stupid or ran into a very obscure issue.

Hello collin80, please start your own thread if you need support for this issue so you and the OP of this thread can both get the individual help that you deserve plus it gets confusing for all involved when more then one person is receiving help in a thread.

Thanks

Any clues in dmesg or 'sudo journalctl -b'?

Try reinstalling the nvidia drivers. This caused it to enumerate the nvidia card for me but then something else was broken that caused the GUI to not come up and I had to use the command line. But, I wonder if you will not have that problem.
