Linux effectively cheats with refresh rates to "hack" multi monitor support. My current laptop reports 50 and 51Hz which are both a lie. It does this via "mode lines", a very outdated way of dealing with monitors. Hell its typically not even a real mode line anymore (ie you put it into your xorg.conf), now things like nivida drivers set them up at xorg load time.
You can fix this with the addition of some modes that have correct refresh rates. For nvidia drivers the nividia-settings can even force it or do it for you. lwjgl3 handles it a bit better BUT you have to do a bit more work your side to ensure you have something workable (TBH i have not got it working properly in jME).
As for pure OS drivers. No self respecting linux user expects games to work on them at all. If we play games we install the vendor drivers that "taint" the kernel in ways only Richard i'm a extremophile Stallman would care about.
