Everything was working fine with my GPU. I had to use boot-repair, and it added grub to some partitions. After that I only get low resolution Ubuntu, it does not detect the driver. nvidia-settings give this
ERROR: NVIDIA driver is not loaded ERROR: Unable to load info from any available system
I went through some questions here, they suggest to edit /etc/default/grub I did that by doing
sudo update-grub, no changes.
