672712 - Blocked graphics table incomplete for Intel and doesn't match about:support

Status: RESOLVED INVALID

(Websites :: wiki.mozilla.org, defect)

Description

[skierpage]

User Agent: Mozilla/5.0 (Windows NT 6.0; rv:5.0) Gecko/20100101 Firefox/5.0
Build ID: 20110615151330

Steps to reproduce:

WebGL pages fail on my Windows Vista Thinkpad, with "Warning: WebGL: Can't get a usable WebGL context" in the error console.

After 20 minutes of searching, I found https://wiki.mozilla.org/Blocklisting/Blocked_Graphics_Drivers . Meanwhile "Is WebGL supported on my computer" at support.mozilla.com suggested I run about:support



Actual results:

Bug 1.  Firefox's about:support says I have "Adapter Description: Mobile Intel(R) 965 Express Chipset Family".  That is not listed in the Intel Cards table.

Instead I used Windows' Display Settings > Monitor > Advanced Settings...  > Adapter to discover that I have a 965 chipset family, with the Adapter String "Mobile Intell(R) GMA X3100".  That looks like the entries in the "GPU family" in that page, but
Bug 2: there's nothing listed in the table for "GMA X3100".


Expected results:

1. Add GMA X3100 to the current table.
2. The table should have entries or a new column matching the Adapter Description from about:support, i.e "965 Express"
3. If that's not detailed enough, then change about:support (a product bug).

I added pointers to about: support and Display Settings to the wiki page. I still don't know if the GMA X3100 is supposed to work, about:support says ""Blocked on your graphics card because of unresolved driver issues" even with the 7.15.10.1576 driver that Windows thinks is up to date. If I override webgl.force-enabled in about:config, the Flight of the Navigator demo seems to run fine.

This text, "Mobile Intel(R) 965 Express Chipset Family", is something that the Intel driver returns. We don't control that. It's a marketing name, of little technical use. Indeed, the "965 chipset family" covers both GMA 3000 chipsets (like the Q965) and GMA X3000 chipsets (like the G965). There isn't much that we can do about this, short of building a complete list of Intel GPUs, which we probably wouldn't have resources to keep up to date in the long term.

The table has GMA X3000, which is how it's often referred to. There's a whole family here, with the X3000, X3100, X3500... I assumed that X3000 was the best way to refer to this family and that people would understand that it really means "anything that has a X, then a 3, then 3 more digits". I'll try to clarify this a bit on the wiki.

I suppose that it would help if about:support linked to the wiki.

Oh, I remember now.

Again, to be clear, as far as we're concerned, GMA X3100 is the same thing as GMA X3000. Sometimes the former number is used, sometimes the other.

http://en.wikipedia.org/wiki/Intel_GMA#GMA_X3100

"The GMA X3100 is the mobile version of the GMA X3000"

Please understand that we can't fill the wiki with a complete list of all product names that Intel ever came up with. We have to group products by families and "GMA X3000" is a good name for the group consisting of X3000, x3100, X3500, etc.

The wiki page clearly says that the required minimum version in your case (Vista, X3000) is 7.15.10.1666. So your driver version is blacklisted (1576 < 1666).
