Presentation tools used ?

Hello All

I am going to give a talk about PostgerSQL, so I'd like to ask you 
people what do you use for your presentations, also I have no idea how 
the remote control works to navigate through slides. I have seen it, but 
never came close to using one.

I have access to google slides and libreoffice Impress.  What tools 
would you suggest ? What's your setup ?

Thank you!
