[SOLVED] WebGL not working in Firefox

[smh377]

I've just installed Mageia 3 on a new Dell Inspiron 14R. All of the hardware works out of the box--no configuration necessary for anything. It has an Intel graphics chipset, which works with OpenGL, but for some reason, Firefox can't detect the GL support, and so no WebGL code works in FF.

Curiously, WebGL demos *do* work in Chromium, but just not Firefox.

Any ideas on what might be going wrong, or what I could do to fix this?

thanks!

What site you using, just gone onto , just checked several and all are working.

Could be the intel graphics bit I suppose

eg.
http://madebyevan.com/webgl-water/

http://helloracer.com/webgl/ Am sure F1 cars don't have reverse. and the wrong tyre manufacture ...

Any of them (e.g. http://get.webgl.org/ is a good basic test).

FF can't see the hardware drivers at all, but Chromium and every other program can use OpenGL just fine..

[pete910]

Could be FF is picky about what it considers GL capable as webgl is built in iirc.

Shows as "Your browser supports WebGL" when I goto that link.

Running FF 17.0.8 on 64bit Mageia3

Right, it sounds like everything works fine for you. It isn't working fine for me..which is kind of why I'm posting to the forum at all.

I've got another older machine still with mga2 where FF detects WebGL without problem. And, as I said, Chromium can run WebGL, and every other program can use GL without complaint.. so, why not Firefox?

What intel graphics is it?

Code: Select all

lspci | grep VGA

in a console and post output if your not sure

As there are some which are blacklisted.

see here https://wiki.mozilla.org/Blocklisting/Blocked_Graphics_Drivers

From lspci | egrep VGA:

Code: Select all

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

And if I go into about:config and toggle webgl.force-enabled to "true" then it does in fact work! So, at least I've got a workaround. I'm still curious why it doesn't detect the driver and work without being forced, but not so concerned now that it's working at all.

thanks!

Cool,

Mark/edit Topic as solved please.

Did you actually read the posted link?
https://wiki.mozilla.org/Blocklisting/B ... ers#On_X11

Of course not. If someone else reads the link, they'll notice that they don't mention the Intel drivers at all (only nvidia and ATI), and that the mageia 3 version of mesa3d falls within the supported libraries (they need 7.10.3+, we're on 9.something). But I didn't read the link, so I'm just making some really lucky guesses here.

In all seriousness, though, what are you referring to? They don't mention Intel graphics on Linux at all.

[doktor5000]

Interesting attitude ... you ask yourself "still want to know, why is that the case ..." after someone else provided you a link to that information. Kinda contradicts itself, no?

Which means they are not whitelisted, and you need to get around the blocking as described here.
They mention all the drivers there which are explicitely whitelisted, Nvidia and ATI.

[smh377]

Yep, and those two, and Mesa - https://en.wikipedia.org/wiki/Mesa_%28c ... raphics%29 - it's not just a software-only renderer anymore...thanks all the same, though.
