1606941 - [Wayland] Graphics hardware info in about:support partly broken

Status: RESOLVED FIXED

(Core :: Widget: Gtk, defect, P2)

Description

[Viktor Jägersküpper]

OS: Arch Linux (with Mesa 19.3.1)

In about:support some graphics hardware information is incorrectly displayed when the Wayland backend is used. With mozregression I found that bug 1556301 is the reason.

Broken:
Vendor ID (now listed as X.Org)
Device ID (now the same as "Description")
RAM (now just "0")

Additionally the information about the display resolution (together with display count) is no longer listed.

Most importantly this breaks the WebRender qualification decision because it now leads to "Unsupported vendor".

Thanks.

Attachment: Bug 1606941 - prefer GLX in glxtest for now

WebRender qualification needs actual GPU vendor info.
It's currently only available through GLX
(eglQueryRendererIntegerMESA is not available yet)
so let's only use the Wayland native path for non-Xwayland systems for now.

Fine, let's prefer GLX for testing for now. With D58656, the test still works without Xwayland, but everything should be as it was before if you do have a DISPLAY from Xwayland.
