Ok, this is what happened:
- linux69 got removed from the repos
- there was an Nvidia driver update and you used Pamac (Add/Remove Software) for your system update
- Pamac might have notified you that he will remove linux69-nvidia due to a conflict
- System update was done but Nvidia GFX is your primary graphics card
- on reboot you only had access to the CLI
When there is a kernel EOL and got removed a different kernel should have been on the system. We will look into a solution which would automatically install needed kernels if a running kernel got removed. We might also check to prevent any updates in that case until a supported kernel is installed.
So this can fix the issue:
sudo mhwd -i linux66
sudo pacman -S linux66-nvidia
sudo mhwd -i linux610
sudo pacman -S linux610-nvidia
