Testing 65 Different GPUs On Linux With Open Source Drivers
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.
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 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.
So go buy a goddamn subscription you cheap motherfucker.
The problem is that games and benchmarking applications require only a single simple OpenGL context but the performance of composited Linux desktops is trash.
SOL
I am sensing a lot of hostility.
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.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
As far as I know the only way to get good gaming performance on Linux is by using the proprietary drivers on a NVidia card.
Has anything changed lately?
I apologize for the lack of a signature.
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.
Nouveau project is a secret plot to make Intel graphics look good by comparison.
It's the best game ever. The GPU can handle it -- believe me.
When I rant about something like that, the typical robotical response I get is "and proprietary software is any better?". There's a lot of hardcore open source fans around here, and you won't get the message across their boneheads, no matter how much it is obvious that open source sucks in that particular area.
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.
Since we're on this subject and I'm too damned lazy to research, I'd welcome any suggestions for cards that play nicely with 4k monitors, preferably at 60Hz, on Ubuntu derivatives, especially Mint.
[FUCK BETA]
While hacking open source drivers for many things is great, it seems like a huge waste of time when the proprietary drivers exist. The end user isn't really to concerned about where the driver comes from so long as it works.
This is not true. For most Slashdot readers it is extremely important that software is open source. Proprietary software is shunned upon. I'm not completely sure why this is, though, but it's just the tradition around these parts. It should be respected.
These people would do as well to stand on a soap box on a public street corner to engage in gifted oration, then hand out leaflets to the crowd suggesting that people express their support and appreciation by signing up for a no-cost-to-your-pocket-book alcohol tolerance study at the local university (to more precisely characterize the vomit threshold for the advancement of medical science) , for which the orator himself receives a small referral fee.
Advertising, much like alcohol, is hardly known as a tonic to clarity of mind. I'll pass, thank you very much. I've far in extreme of the Mormons on the issue of what passes into my brain through my eye sockets. Alcohol only makes me vulnerable to the lizard housed within (he's not so bad, really, once you stare him down). Advertising, on the other hand, exposes me to spitting cobra exotoxins. The dead giveaway is the spinning iris of seduction: animated GIFs, Flash-based logo rotations, pop-ups, pop-overs, all resembling nothing so much as a vulture with the twitching tail of a live and highly agitated squirrel shit to the ischium out of the vulture's ass.
Shall I welcome this bubonic creature to peck at my eyeballs from the side of my screen? Even for "Four score and twenty" or "I have a dream"?
Nah. I don't think so. Not unless I've got a bag full of Shuriken ice picks and it's somebody else's HD monitor.
They paid for their bandwidth and he paid for his.. Now they want him to pay for theirs too? Who's the cheap motherfucker again?
Just pass the test the same way you could in 2000 and download the NVIDIA or AMD driver from their websites. If you want a dead simple answer without artificial restrictions that's all you have to do - instead of whining about how your artificial restriction is making things hard.
In fact such a post makes you look so stupid that I strongly suspect you have an agenda to push and do not care if you look stupid to many so long as you manage to fool the naive. Is that what is going on here?
You could conceivably say that of the 65 tested, "only" 15 did not have good enough OpenGL support. This...other...usage of the word "only"...I do not think it means what you appear to think it means...
Wow, you are a nutter. And like most nutters, you won't even be able to see it.
The proprietary driver works today. Tomorrow, it stops working. It's happened to me and probably to any linux user, your computer gets a few years old and the manufacturer drops all support for your card for newer kernel versions. Better hope there's an open source driver.

A subscription for Phoronix? The site that yesterday published a multi-page article comparing Clang and GCC's OpenMP performance using -O0 for Clang and -O2 for GCC? I'm sure that's a good use of money...

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 contributors - some corporate other independent).

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.

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.

The interesting part, is that the guy is building a test-farm infrastructure.
The kernel benchmarking/bissecting stuff could be automated and could become part of the normal development project.
(Having the test farm continuously benchmark key linux project (llike kernel, mesa, etc.) while they are developed).
That is going to be:
- a very valuable ressource for linux development
- a service that can be sold or that can be sponsored by big player (Valve co-financing the mesa/gallium continuous benchmarking ?)

He is... They happen to be providing content that is useful in this particular case while he's not providing anything in return
