So after some trail and error found out that lubuntu isn’t so light as it is presented but bodhi linux is.
So i switched to bodhi linux and sure enough I can work now with my vscode opened google chrome and the rest of the tools i need without a problem.
So if anybody else is having issues give this distro a try.
