You can see the "metamodes" was to setup the screen positions and rotation. Please note that the monitor on left is rotated.
"DP-0.8: nvidia-auto-select +0+503 {ForceCompositionPipeline = On}, DP-0.1.8: nvidia-auto-select +1920+0 {rotation=left, ForceCompositionPipeline = On}"
However, issue 2 is bit tricky. After some trial-and-error, I found that the sequence of screens declare on the "metamodes"did the trick. The last screen shows the text in text mode. So, I swapped the DP-0.8 and DP-0.1.8 in the "metamodes":
"DP-0.1.8: nvidia-auto-select +1920+0 {rotation=left, ForceCompositionPipeline = On}, DP-0.8: nvidia-auto-select +0+503 {ForceCompositionPipeline = On}"
Now, it works perfectly.
