An anonymous reader writes "How good are open source graphics drivers in 2014 given all the Linux gaming and desktop attention? Phoronix has tested 65 different GPUs using the latest open source drivers covering Intel HD Graphics, NVIDIA GeForce, AMD Radeon, and AMD FirePro hardware. Of the 65 GPUs tested, only 50 of them had good enough open source driver support for running OpenGL games and benchmarks. Across the NVIDIA and AMD hardware were several pages of caveats with different driver issues encountered on Linux 3.15 and Mesa 10.3 loaded on Ubuntu 14.04. Intel graphics on Linux were reliable but slow while AMD's open-source Linux support was recommended over the NVIDIA support that doesn't currently allow for suitable graphics card re-clocking. Similar tests are now being done with the proprietary Linux drivers."

    Right now, there are practically no reasons to focus on video drivers and graphics acceleration for Linux. DVDs and GNOME 3 are barely enough to scratch the surface. Once games come in and improve the driver landscape, there are all sorts of things that will benefit from access to the video cards' power.

    • Interestingly Valve doesn't merly influence the market by their game being a reason.
      They actually do directly help progress with actual code.

      See reports on the same Phoronix website of various OpenGL 4.x extension being added to Mesa by Valve.

      One day, when the Mesa finally achieves full opengl 4x compliance, you'll know it's partly due to developer on Valve's payroll (in addition to those on Intel's and AMD's payrolls, and the independent volunteers in Nouveau project, and the thousands of other contributor

    I recently updated my Mint install and discovered that the newer AMD/FGLRX drivers have a big issue with the backlight on various laptops (mainly, that they turn it off or down to zero).
    At first I thought I had no display, but later noticed that if there is some front-light I could vaguely see the login window.

    As it's an older model, it seems to get less attention from AMD (Nvidia is much the same). However, I was happy to see how much better the FOSS driver seems to work these days, so for now I'm back to using that. Backlight works, and video seems reasonably fast. I haven't tried any 3d/gaming yet but it will be interesting to see how that stacks up.

        I second this.
        I installed Linux Mint 17 recently and first went with the AMD proprietary fglrx drivers.
        Overall any video (file playback or gaming) would always be choppy and jittery.

        I decided to give the open source radeon drivers a shot. The performance is much better. All the choppiness/jittery is gone.
        I may have lost some fps but it was completely worth it.

        The open source driver needs to be good; the latest version of the ATI proprietary driver has dropped support for relatively new cards - anything before HD 5000 series. This means that cards that include very good h.264 decoding engines such as the AMD Radeon HD 3850 256MB reviewed can no longer use the latest driver. In Ubuntu 14.04 this also means that trying the older last-supporting driver version no longer works, one would need to downgrade the x server version used in the distro.

      Honest question. Outside of certain Linux packages/distros and kernels pissing and moaning about loading proprietary drivers why not use them? If you are simply "using" the graphics card there is nothing against this that I can tell, just not recommended by Linux developers because it's anti GPL by nature.

        The GP *was* using the proprietary drivers. He was complaining that they were broken, and to his surprise the FOSS driver worked better.

            Yeah, to be specific, fglrx (proprietary) worked very nicely until an update (I believe a combination of new backlight functionality in a recent kernel and/or updated fglrx) caused it disable the backlight in X11.

            I went back to using the GPL driver, which is working much nicer than it was the last time I used it. This is good because otherwise I'd have to choose between slow unaccelerated video (suck) or dim barely visible video (more suck).

              I think my bigger concern is when people make a stink about performance while using the open source driver. The open source driver is not a performance driver and never has been, it's a compatibility driver. If you want performance, you are not running older hardware and not running with older drivers.

              I can see running the benchmarks to find out what works, but people will complain about and ridicule the benchmarks as given. That Windows can't run worth shit without proprietary drivers does not make a di

      • For me (a relative non-techie for this site) I find the more open-source I have on my computer, the easier it is to update the system without things breaking. I can just go to synaptic and check all updates and let it run. A lot of proprietary drivers don't play nicely with the package management, or require a manual install. Aside from that I also find them a bit glitchy, although there's no denying that if you need fps then there is no alternative.

      And that's AMD official stance:
      - once the opensource drivers get good enough, support for older cards gets removed from catalyst, and radeon is pointed as the official go-to solution for older cards.
      - so catalyst = drivers for the current generation of cards (unless you want to beta test the bleeding-edge development) and radeon = drivers for all the previous generation (unless you want specifically a card that still isn't phased out yet, probably because the current openCL support is better in catalyst).
      - that's also part of the reason why AMD has opensource driver developers on their payroll.

      • by phorm (591458)

        And that's totally fine by me, so long as the FOSS drivers are relatively within the performance/feature threshold of the proprietary ones by the time the hardware is no-long supported by Catalyst.

        In my case the hardware is effectively supported by the fglrx/catalyst drivers in the aspect that they still detect it and install, it's just that there's a new bug introduced. I've seen various other laptops that also seem to be bitten by this (mainly Asus and I think some Acer) so it may be that it'll be fixed b

    I have an old Radeon X1950PRO in guest/spare PC. While it's getting long in the tooth it's still good enough for some Star Craft 2 and Dota 2 action with friends. Unfortunately I have to boot to windows 7 to get decent performance. The kernel devs are always changing the driver interface, so the last time I was able to use the proprietary drivers was around Ubuntu 6. Now in Linux my only option are buggy, glitch drivers like Phoronix described in their drivers or booting to Windows. The hardware specs were released. Now if after 8 year, the open source drivers are still buggy and slow, they will never be as good as the proprietary. What Linux needs a stable driver interface like Windows has.

      Windows does not have a stable driver interface. What windows does have is the market share necessary to not suffer too much when the interface changes.

      In any event its inexcusable in both cases to ever undergo more than 1 driver interface change per architecture. I get it.. at first you do something that works but later the design proves inadequate, so the second time around it should be designed right. Pick an ABI and stick with it, and design to be extensible.

        Their interface is stable per version of Windows. They freeze the ABI and it is set until the next one. They don't change it much usually anyhow, Vista being a notable exception. Now of course when new DX features come out you have to update your drivers to support it if you want those features, but it isn't necessary to make your driver work, the old driver continues to work.

        It does not get updated with every kernel patch, ala Linux.

        Windows does not have a stable driver interface. What windows does have is the market share necessary to not suffer too much when the interface changes.

        In recent history there was WDDM 1.0 (Vista, 2006) 1.1 (Win7, 2009) 1.2 (Win8, 2012) and 1.3 (Win8.1, 2013) and as far as I can tell they're backwards compatible - if your graphics card has a WDDM 1.0 driver you can still run Win8.1, however it'll also cap your DirectX level. Unless I'm mistaken that's 8 years of a stable (but expanding) ABI, it seems like DirectX 12 will require WDDM 2.0 which may be the next clean break but we won't know until Win9 is out. But I agree that the market share helps Microsoft a lot, particularly the market share of gamers despite Steam now being on Linux - according to their May 2014 survey 95.5% run Steam on Windows. Also for all those pointing to Distrowatch, at least 0.64% of the 1.10% running Linux use Ubuntu with only 0.08% verified as Mint...

        • Going with distrowatch numbers is complicated, as it seems to be promoting/pushing not so good distros, and then either all the users are retarded, or something smells fishy, either the statistics are damned lies, or even the users might smell fishy, as in conspiracy and stuff, ya know.
        • And one day, once Mesa and DRI/Gallium etc. mature enough you'll probably going to have a similar landscape in Linux.
          For now, it's "work in progress" zone.

      • Windows XP still has ~25% market share. If Linux users were still running whatever version of Red Hat came out in 2001, it'd probably have good driver support by now.
    • I have an ancient X1650 card with my main monitor on the analog VGA and TV on the DVI. Every Linux distro ignores my X config and makes the monitor some miniscule resolution like 320x240. However if I unplug the TV its fine. This happens even with the TV powered off.

    I just wanted to say that Phoronix is an undervalued gem. These guys (I think just one guy actually) puts in the grunt work to get us hard performance numbers. He's developed a fully automated testing system that makes it easy to bisect kernel patches to identify the source of kernel regressions. I get the impression he runs on a shoestring budget out of his house but the work he does is the kind of thing that OS vendors of old used to dedicate entire teams too. He really ought to be fully funded by some group like the Linux Foundation because his work is invaluable in that nitty-gritty unsexy way that really helps out more visible engineering.

    The real trick for Linux compatibility is the ability to go to a box store, buy a new graphics card (or any device) Plug it in into your PC and see if it works, works without having to spend hours finding the driver for your common distribution, and works well.

    That has been my biggest problem with Linux support.
    It is a case where a particular component failed on my computer, and I need a new one right away. Being that your computer is down, you are unable to research what you should get. So you go to the store look around and find something that would seem to work with your computer. A name that you recognize, and specs that are probably better then your old one.

My 80 year old grandmother I think might have just one... but she's not going to be researching hardware for her linux desktop build by herself either.

      My biggest gripe with Mint is that a few versions ago they removed the option to do a non-graphical install, and also switched to using Nouveau by default, which for some reason locks up after a few seconds on my laptop, meaning I have all sorts of issues trying to install Mint on it.

      If you favor open-source games, the Radeon drivers, especially on 6000-series cards, have been absolutely excellent. The GCN architecture change certainly stalled progress, as well as the need to shoehorn GLAMOR onto the stack (no 2D acceleration hardware on GCN cards). Performance is definitely getting close, though, and Intel is even putting work into GLAMOR now, allegedly because it shows more promise than even SNA as an EXA alternative.

        The open source Gallium3D driver for Southern Island Radeon GPUs has come a LONG way in the recent months. Given a 3.14+ kernel and the soon-to-be-released 10.2 Mesa libs, you can expect performance within 80% of that of the Catalyst driver, and it only keeps getting better. The stability is also pretty good. I love being able to flip smoothly between a full screen game and a chat window or a Web browser.

    I bought a 6870 as an upgrade to my Mac Pro, mainly because it was highly compatible with OS X (it only fails to show the grey apple screen during boot) and is far cheaper than officially-supported cards. It's also a good mid-tier card on Windows.

    And according to this, the 6870 is also basically the best card for use under Linux using open-source drivers, so I guess it's just a very good card in general. When I do a new from-scratch build, I might put Linux on the old Mac so I can play around with Linux gaming more.
