From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How is the external display connected? I have never seen Freesync over HDMI work. The early implementations were AMD proprietary and the new ones require HDMI 2.1 which has some ridiculous bullshit about not being implemented by open source drivers. HDMI sucks, use DisplayPort if possible. If your laptop doesn't have a DisplayPort connector, try a USB-C to DisplayPort cable, as usually the type C ports on laptops support DisplayPort alt mode.
Yeah I agree that HDMI sucks but unfortunately my Laptop doesn't have any Display Port and my USB-C port doesn't have display port alt mode.
Is this your experience on all OSes or on Linux only¿? AMD does mention on their website that many displays support freesync over HDMI.
