When I use Ubuntu 17.04, 16.04, or Linux Mint 18.1, I hear coil whine coming from my CRT. When I use Windows 7, or Linux Mint 17.3 using fglrx drivers, I get no coil whine (Windows I use solely for gaming, Mint 17.3 is acting up). While it may seem that the coil whine goes away with fglrx because it's suited for older hardware, on Windows 7 I use the latest ReLive drivers, and have no coil whine. I use dual monitors.

Is there any way to solve this?

The resolution and refresh rate will affect coil whine (specifically, the horizontal refresh rate, which is the refresh rate multiplied by the vertical resolution plus a vertical blanking interval). It's likely that you are using a different refresh rate or resolution on Ubuntu as you do with Windows or Ubuntu with fglrx drivers.
