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."
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.
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.
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.
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?
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.
