1. 3

    Sounds about right. I’m stuck with a 2K resolution on a 4K screen and no HDMI sound. Even picked a pricey GPU that’s supposed to be well supported. Can anyone suggest an AMD card that supports the above?

    1. 3

      I currently have an AMD RX580 and use dual 1440p monitors without issue. I have also tested another 2x 1080p simultaneously with those 2x 1440p. All at 60Hz. So it can definitely push the necessary pixels for 4K on Linux. You need a more recent Linux kernel (4.8 or above iirc, I’m on 4.12) for the newer AMDGPU driver. There are some improvements to be made on certain codec playback support (I get occasional tearing on VP9 at 1440p for instance) but ever since the switch to the AMDGPU stack I have a lot of confidence in AMD fixing things as time goes on.

      My previous Nvidia card was supposed to support 2x 1440p, but wouldn’t run the second one at the correct resolution, instead limiting it at some odd resolution of 2160x1200 (iirc?). Would not work in nouveau, would not work in the latest proprietary drivers.

      As for HDMI audio on the RX 580, I am traveling but will try and test when I return home. I don’t know if I have an HDMI audio device though.

        I believe HDMI audio is still not available ootb until a set of AMD patches (that have been around for quite a while now) are mainlined.

          Yeah, HDMI audio with the latest AMD cards got pushed back when their big code dump was refused back in the spring. They’ve been rewriting it to use kernel APIs instead of wrappers ever since & the main code merge was accepted by Dave Arlie a week or two ago IIRC. So, barring some ironing out of wrinkles, 4.15 looks hopeful.

      2. 2

        I have an R9 390X that drives 3840x2160 + 1920x1080 all at 60Hz in Linux without issue. I’d do some research, though; I don’t even come close to stressing it in Linux, it’s there so the Windows install on that machine can run games.

        No idea about sound, my monitors are connected over displayport and dvi, respectively, and my speakers are plugged into my sound card.

        1. 1

          Even my old intel i915/i5 testing setups can push 60Hz@4K, it’s likely that it’s not about your card but rather about the combination of (GPU, connector, cable and display) or bandwidth saturation. KVMs and similar stuff in between can mess with the negotiation. For 4k@60Hz you want a chain capable of HDMI-2.0 or DisplayPort. It might simply be that Xorg probes the connector, gets the choice of 2k@60Hz or 4k@30Hz and picks the former.

          AMD cards won’t give you HDMI sound on the open source drivers unless you manually integrate their HAL patches. The relevant fixes are slowly trickling in, and chances are that in 4.15 the support will get there. But really, “recent” features like display-port chaining, event-driven synch like FreeSync etc. all have spotty support and its a gamble if it will work on any given card.

          1. 2

            I’m using the DisplayPort cable that came with my monitor. I can set it to 4K but the DE becomes unusably sluggish on both Wayland and Xorg. Thanks for the pointers.

          I’m not a designer, but I think it looks cool. My one quibble is that using j/k turns it into a different mode that you can’t escape from. I think that either it should be full-on modal where you start in details mode and switch to title mode by hitting some key, or else just choose one mode.

          Edit: Never mind, I misunderstood how it worked. It would be nice to be able to collapse an article that has been put in details mode though.

          1. 1

            Scrolling with the mouse puts you back into headline-mode so you don’t have to scroll past entire articles. I could bind the Escape key to keep you in headline-mode when you’re using the keyboard to navigate or to just collapse the current article. I’ve been meaning to add a few more shortcuts, e.g. s to save.

            1. 1

              Hmm, I’m not seeing that behavior. The articles which aren’t in headline mode stay not in headline mode when I scroll with my mouse.

              1. 1

                Yes, expanded articles stay open. Collapsing them as you scroll down would move the rest of the page up (unless I make the page scroll in the opposite direction automatically.) I’m not sure if there is a real reason to close articles after you read them, they disappear from view as you keep going down.

                I haven’t really though of it as being modal. The headline view is the default but it’s tedious having to press two keys (j, o) if you just want to read articles or see the images. If you’re just interested in headlines you would hit j (or the space bar) repeatedly or use the mouse. I realise people use the site differently though, I appreciate your view on this.
