I have been a Windows user for the past decade or so and I switched to Linux just for a change. I have observed that there are so many Linux distributions available, and each distro has several desktop environments. If somebody asks me where the control panel is in Linux, I have to ask my own questions about which distro is installed.
The answer for this would be simple if the user is on Windows or Mac. My question here is: can we have a simple/common user interface for everything in Linux?
