[Rant]: RX 5700... a frustrating experience
Tuxee commented on 28 March 2020 at 1:11 pm UTC

subDo you have a spare old HDD?
I even have a spare NVMe SSD in an USB3 case :-)

subAny chance of just giving Arch a try?
I had zero (apparent) issues so far.
And I didn't manually build the driver stack
and fiddling with the BIOSes.
Just the plain experience.

Reading through this thread it gives the experience
that AMD still struggles with Navi.
But from my POV that's absolutely not the case.
Neither on Linux nor on Windows.

As stated already: My 5.3 kernel with Mesa 20.0 works pretty much flawless, too. It just took its fair time getting there and I didn't expect any regressions. The last couple of 20.04 boots (kernel 5.5, Mesa 20.0, BIOS back from November) went smooth again...

So Arch might be fine for some time. Or for several boots.

subReally, don't know what's wrong with your setup. XD

Sorry.

Neither do I. But reading through the various bug reports I might not be the only one.

Edit: How many displays do you use? Seems as if some issues stem from multi-monitor setups.

Only one. A TV screen to be exact. This is a sofa gaming setup.

You might be right that this only happens if you use multiple display outputs (or a specific single output). I'm using the HDMI only.

I have an ASRock one too. Have you read the smallprint before downloading and upgrading to the latest BIOS? For my model they don't recommend upgrading the bios past a certain version for some AMD CPUs.

Well, upgrading made sense: With the most recent upgrade I can finally run my RAM at 3600MHz. Before that I could only go up to 3200. And I can't detect any problems with the CPU.

I've got 3 different Radeon cards that work with amdgpu, not one of them could generate a functional mutli monitor setup without a massive hassle. None of them work ootb with a vga monitor I've got. I just got a 5700 and it took me hours and hours to get a working multi monitor setup. I had to hook my Acer monitor up to my NVidia system and export an EDID file and then figure out the horribly documented kernel switches needed to get the EDID file read so the monitor would work at over 800x600. I also had to include the edid file in the initrd (not 100% sure this was necessary due to the aforementioned bad documentation but what I read seemed to indicate that amdgpu uses early KMS and requires the EDID in the initrd). The end result is great but a massive amount of work needs to be done to get EDID reading and multi monitor setups to work. I shouldn't have to have a NVidia box around to generate edid files so that my AMD video card can display to a monitor properly.

I saw some edid progams available in Ubuntu (read-edid, parse-edid???) but couldn't get them working in Fedora. Getting properly functioning monitors shouldn't be this complicated.
