Firefox 4 hardware acceleration

x33a · 2011-04-01 08:51:11

Hello fellows,

has anyone got hardware acceleration working on linux with firefox 4? I have checked "use hardware acceleration when available" under the preferences, but in the about:support page i get:

GPU Accelerated Windows 0/1

I am using nvidia binary with 8600gt card. I know that hardware acceleration for linux is very buggy, but i read it somewhere that it is supposed to be working nicely with nvidia binary drivers.

Please post your thoughts and experiences about this.

I think there are still issues with flashplayer and hardware being enabled.

Try starting with

MOZ_ACCELERATED=1 MOZ_GLX_IGNORE_BLACKLIST=1 firefox

Works for me on r600g but makes it actually slower. Maybe it's better with nvidia proprietary.

Launching Firefox the way Cdh mentioned enables acceleration. However, in my case, with nouveau drivers and gallium I experience frequent browser misbehavior -- e.g. when scrolling 'code' boxes on the forum color artifacts appear on the screen, some Youtube videos load with malformed picture (reloading several times seem to help), performance issues are common as well. Ffox without acceleration works very well, though.

It works well only with the Nvidia driver (the closed one), you can see that on the official mozilla wiki

No issues here, but I didn't see anything ... different.

I can't agree, intel gma965 here, the result:

What you need to differentiate here is WebGL and layers acceleration. WebGL is whitelisted only on nvidia cards. Opengl layers acceleration is turned off by default on *any* card, because it's not ready yet in Linux. But that doesn't mean layers aren't accelerated. They are, just not with opengl, but through xrender. That's why the FishIE test works quite well even on low end intel cards. Same goes for the psychedelic test: http://ie.microsoft.com/testdrive/Perfo … cBrowsing/

With 20 fish, it can go well on any system. It should go well with much more fish:

Thanks that did enable hw acceleration, but in my case too, actually made the rendering slower.

On this site:

http://demos.hacks.mozilla.org/openweb/HWACCEL/

Without acceleration, my old p4 managed 45+ fps, and with acceleration it managed only 10-15 fps.

I don't know what exactly the problem is, but i think i'll pass on this, till it gets more stable.

Thanks for the input everyone.

In my case (core i3 graphics). Nothing really change. With acceleration the result is pretty close to normal. Except I think it's a bit more unstable since the frame rate drop a bit some times.

I've got 30fps with 250 fish, 21 fps with 500 fish and 8-9 fps with 1000 fish for intel gma965 in linux it isnt that bad.

Much slower with the "acceleration" enabled indeed. It must still need a lot of work.
Opera and Chromium both handled 20 fish at about 30FPS, and quickly dropped off from there.
Firefox 4 on the other hand did quite well with acceleration off ... it held 60FPS up to 500 fish, and dropped to only 35FPS at 1000 fish, not too shabby after all.
With "acceleration" though (and propietary nvidia drivers) ... 50fps with one fish, drops off to 30fps by 500, and down to about 22 with 1000 ...

Well, Acceleration is nice but I'm pretty content with firefox right now. Even without graphics acceleration the speed improvement is nice.
