Bug ID: 202449 Summary: vrr_capable not showing up in xrandr with eDP display. Product: Drivers Version: 2.5 Kernel Version: 4.20 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: haxk612@gmail.com Regression: No

xrandr doesnt show vrr_capable option for eDP display but the option is there with HDMI. While its true that my internal display on laptop doesnt report that it supports FreeSync but i know that it works with Freesync because when i edit EDID in windows freesync works. But im sure the issue isnt that my display doesnt report Freesync since when i connect a monitor that i know isnt freesync capable to HDMI the option is still there.
I attach output of "xranr --props" of my laptop.
Laptop has Ryzen 5 2500U with VEGA8 (Raven Ridge) and dedicated RX560X.
VEGA 8 is connected directly to internal display (eDP) and RX560X is connected to HDMI port.

--- Comment #1 from Haxk20 (haxk612@gmail.com) --- Sorry after further reading im not sure that dGPU is connected to HDMI directly. Is there a way to see in linux ?

I'm not sure if this will actually let you use variable refresh rate features but this should attach the properties for your eDP panel at least.

Gonna compile right now. I surely wont be able to use vrr still since i need to edit EDID to report a freesync range but at least eDP now has a way to enable it. Thank you.

This fixes the issue. I know its too late for this to be sent into 5.0 but can you send this into drm-next-5.1-wip so that this makes it into 5.1 ? Thank you.
