770688 - about:support should explain why graphics acceleration is disabled

Status: RESOLVED DUPLICATE of bug 1801780

(Core :: Graphics, enhancement)

Description

[Jesse Ruderman]

When graphics acceleration is disabled, about:support should say why rather than just saying "0/1 windows are accelerated".

e.g.
* Firefox does not yet use acceleration by default on Linux (bug 594876)
* Firefox is not familiar with your graphics card
* Your graphics card is known to be problematic
* You need to _upgrade your graphics driver_

There's a message in the "0/1 windows are accelerated" line [1] when the graphics system provides one [2].  If you're not seeing a message, nsIGfxInfo.getFeatureStatus likely returned FEATURE_NO_INFO, so about:support doesn't have any message to show.

Assuming that the front-end uses getFeatureStatus correctly, and that status messages should originate in core and not the front-end, I'm moving this to Core::Graphics.  But the bug would be more helpful if it described a particular situation or system where a message should have been shown but wasn't.

Actually this looks similar to bug 673490.
