I didn't read the whole thread (it's too big), but I noticed the last two posts and on one side you are saying that you work with optimus-switch but show optimus-manager status. Those are two DIFFERENT things and you shouldn't have both solutions at the same time, just as you can't have two antiviruses on the same time on Windows.
Also, when copying the output from terminal, maximize window so you could copy THE WHOLE part. Your output above is just partial:
Error is : Failed to execute '>**
Execute what? We can't help if we get incomplete data.
Alternativnelly, when you still have fragmented lines even in maximized mode, simply output them to text file with
> text, so for example
sudo systemctl status optimimus-manager > optimus-manager-status.txt
This will create
optimus-manager-status.txt file with the output, so you can open it, copy relevant parts and post here.
Mine is even bigger:
However, system boots as quick as before or maybe this 1,5s is so little I didn't notice any difference. Did you? As long as it works and didn't disturb me in any way, I wouldn't care about that result.
