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.

Since people normally only report on negative experiences: I was lucky enough to get a reference AMD 6900 XT during the GPU shortages.
Switched from Ubuntu to Fedora for it because Ubuntu didn't have firmware for it yet.
Ever since then it has been a rock solid GPU. Never even had such a stable GPU under Windows.
Have been running Fedora with Wayland for more than 2 years now and can count the crashes on a single hand, most were my fault.
I'm sure once that issue is sorted out that GPU is going to ride along for years with minimal maintenance required.
(You might want to downgrade your kernel until then though)
I couldn't get my 6900XT to drive my G9 at 240Hz, but 120 isn't too bad. I should probably try again soon.
Been 20+yrs of some random flavor of driver problems for me, since my 9700 Pro at the very least.
Over DisplayPort? That's interesting, I knew AMD can't do HDMI 2.0 but there shouldn't be a problem with DP.
Might wanna try a proper new certified DP 2.1 cable, just to be safe.
I "only" drive a AW3423DW but no issues at 3440x1440 with 165Hz.
Indeed over DP. It works fine at 240Hz in Windows, but of course the graphics quality in games is not as good as with nvidia.
Anything interesting going on in the kernel log while connection doesn't work?
If so, you could maybe write a bug report at the amdgpu repo.
One thing I could imagine that is happening is that Linux chooses a higher chroma subsampling than on Windows. Had that issue before with a monitor that had a wrong EDID. Unfortunately it's a real pain to set the chroma subsampling on Linux with AMD.
