[xubuntu-users] plug-and play monitor loses configuration

[pereira]

Jordan,

FYI I got a videocard specifically to support this system,
a GeForce GTX 960; the driver is  352.79.

According to the specs, this card supports the monitor that
I can tell. I don't know the differences  between the drivers.
