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.

I wasn't able to enable VRR on my monitor (with freesync). I'm using KDE Wayland on Debian Testing, just wondering if you knew a workaround or something?
What kernel are you using? Debian tends to lag behind with kernel updates which makes it a bad choice when running new hardware. I switched from Debian to Arch when I got my A770 because at the time Debian's latest kernel even in sid didn't support Arc at all while it worked fine in Arch.
I'm running 6.5.10, also with an A770. I could maybe try/compile 6.6 later, but 6.5 seems new enough I thought.
Hmm, 6.5 should support VRR just fine yeah
Yeah no change with 6.6, I guess I'll probably open an issue somewhere when I have the time to figure out what's broken.
Just to make sure, you're using DisplayPort right? I don't think the Arc cards support VRR over HDMI. The HDMI port on the Arc is actually a built in DisplayPort to HDMI converter, and I don't think any converter chips support VRR modes.
Yep, it's definitely using DisplayPort!
Okay so for whatever reason, turning Freesync on and off a bunch of times from the OSD and then replugging works until the next reboot, so I've dumped the working EDID and I'm trying to figure out how to load it at boot (~~but I'm not having much luck~~).
For reference, the monitor is a Samsung LC24RG50.
Edit: Got the EDID loaded, KDE says it's supported, but VRRTest doesn't really seem to do anything.
Edit 2: Other games work fine.
