Upgrade Nvidia driver on windows, ubuntu won't boot

nl flag

I have a computer with RTX 3080, which I dual boot Windows 10 and Ubuntu 20.04

I had nvidia-driver-460 installed on Ubuntu, which worked fine. Yesterday I updated the driver on Windows through GeForce Experience to 466, after this Ubuntu won't boot. I didn't change anything on Ubuntu.

I thought that drivers on Windows and Ubuntu are independent and should not affect one another.

I have tried upgrading the driver on Ubuntu, reinstalling, trying older drivers, but nothing works. Ubuntu only boots with nouveau, but it doesn't detect my second display.

What can be the problem and what should I do to solve it?

If I uninstall Windows and reinstall Ubuntu only, would that solve the problem or did the driver change the graphics card itself?

EDIT: I have removed quiet splash from grub settings to try diagnose the problem, but it won't even show any messages when using nvidia driver.

What you install on one does not affect the other.

I have managed to get it working by installing nvidia-driver-460-server. I'm not sure whether it is working correctly, but I have both my monitors at correct resolution and nvidia-smi is working properly.

I have thought to install server driver because nvidia-smi was freezing the computer with normal driver even from root shell. So I thought to install just the server part to run my AI tasks, but surprisingly after installing server driver I managed to boot successfully.

I'm not sure what is the difference between normal and servers driver, but just happy to get it working at all.

One thing that comes to mind is that GPUs have a firmware. Maybe it got updated during the drivers update on W10 which broke it for older drivers on your Ubuntu? Just a theory, though. Something like this: https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/

Most likely, or vBIOS somehow got updated by GeForce Experience. Not sure why on Ubuntu the server driver is working, but normal one doesn't.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
