It happened when I tried to set up dual monitors.
I have an RTX2080ti with 3 HDMI and 3 display ports; I was using a single monitor connected via HDMI. Then I tried adding a second one but I didn’t have any other cable than a VGA at the moment so I plugged it in the mainboard GPU which is “Intel Corporation UHD Graphics 630 (Desktop 9 Series) (rev 02)”.
Then I found out that I need to actually plug the monitors into the same GPU; got a DVI-to-HDMI cable for the second monitor (no HDMI ports on that monitor) and plugged it in the RTX. Nothing happened. Reboot. Now even the first monitor wasn’t working. After some switcheroo on the RTX ports and multiple hard reboots, I plug one of the monitors back into the Intel GPU and it works. But the RTX GPU doesn’t work anymore.
This one is the closest to my problem I think - nvidia rtx 2080 ti - dual monitor stopped working - smi driver not loaded - ubuntu 18.04.2
I followed the steps proposed there and here are the outputs:
grep nvidia /etc/modprobe.d/* /lib/modprobe.d/*
/etc/modprobe.d/blacklist-framebuffer.conf:blacklist nvidiafb
/etc/modprobe.d/nvidia-installer-disable-nouveau.conf:# generated by nvidia-installer
/lib/modprobe.d/nvidia-kms.conf:# This file was generated by nvidia-prime
/lib/modprobe.d/nvidia-kms.conf:options nvidia-drm modeset=0
no blacklist nvidia file
did sudo update-initramfs -u and reboot
This is the output of

and
sudo modprobe nvidia
modprobe: ERROR: could not insert ‘nvidia’: No such device
furthermore I can’t even see the gpu with lspci:
lspci | egrep -i "vga|display|3d"
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Desktop 9 Series) (rev 02)
other things i’ve tried (in order):
prime-select query shows nvidia; also tried setting to intel and back to nvidia and rebooting
deleted /etc/X11/xorg.conf
set the nvidia-drm modeset=1 to 0 and sudo update-initramfs -u and reboot
added PrimaryGPU Yes to /usr/share/X11/xorg.conf.d/10-nvidia.conf
resulted in login loop. reverted
disabled wayland
also resulted in login loop. reverted
