recently, I've seen few users running Fedora with nomodeset. They didn't know about that and were just complaining about poor resolution and/or performance (and those systems worked just fine without nomodeset). Also, sometimes, users choose basic video driver because something is broken, but the broken state can change over time. 

That led me to an idea - wouldn't it be better to provide some info for users running Basic Video Driver that they're probably not getting the best Fedora experience?

What came to my mind? 

Having two GRUB entries for Fedora - with and without nomodeset. Users who would install system while booted with nomodeset would see grub every time with nomodeset option being default for the first time and then defaulting to the last used entry.

Apart from this, there could be either notification (or window) shown every time GNOME is launched with basic video driver, probably with some basic information and link to Fedora Docs explaining what that does mean.
