Remove unnecessary icon from indicators

Is there anyway to remove this ugly and unnecessary icon?
I remove 'indicator session' from startup programs but has no effect.

Remove the indicator-session package from your system - the indicator will be gone for good after the next login.

sudo apt remove indicator-session

As a side note - it's always been desired to appear in the top-right, like pre-Unity times, which has finally been fixed in 19.10 and onwards.



Another way to get what you want without removing anything is to just disable the service and reboot.

pkexec to get temporary admin rights, navigate to /usr/lib/x86_64-linux-gnu/indicator-session/ and rename indicator-session-service to indicator-session-service.disabled. Close super user and reboot.
