1739476 - glxtest error when starting ESR 91.3.0 on Linux via ssh X forwarding

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect)

Description

[James Pearson]

When starting ESR 91.3.0 on Linux (CentOS 7.9) via ssh X forwarding, the following is output to the terminal:

Crash Annotation GraphicsCriticalError: |[0][GFX1-]: glxtest: X error, error_code=1, request_code=143, minor_code=32 (t=1.85423) [GFX1-]: glxtest: X error, error_code=1, request_code=143, minor_code=32
Crash Annotation GraphicsCriticalError: |[0][GFX1-]: glxtest: X error, error_code=1, request_code=143, minor_code=32 (t=1.85423) |[1][GFX1-]: glxtest: process failed (exited with status 1) (t=1.85432) [GFX1-]: glxtest: process failed (exited with status 1)

Firefox appears to start and work OK

This doesn't happen with ESR 91.2.0 via ssh X forwarding

Starting ESR 91.3.0 directly on a workstation doesn't output these 'errors' - only happens when using X forwarding over ssh

I'm assuming the errors are harmless?

The error is most likely caused by:

95c4aa0fd3dab04aec9981111cc3da2ad1d400b6 Robert Mader — Bug 1710400 - Blocklist HW-WR on Intel DDX driver, r=aosmond a=RyanVM

bug 1737499 comment 16 found out that a minimum version check is required for xrandr because X11 forwarding has a different and extremely outdated xrandr version.

This was fixed in FF 95 by https://phabricator.services.mozilla.com/D129522 / bug 1737499. For ESR we'd need to backport the toolkit/xre/glxtest.cpp part of that. Ryan, can you do that easily or should I prepare a patch?

Go ahead and post a backport patch here and request uplift.

(In reply to Ryan VanderMeulen [:RyanVM] from comment #3)

Go ahead and post a backport patch here and request uplift.

Ah, I see, the backport was not completely trivial (which is why I didn't do a backport right away). Uplift request in bug 1737499 comment 29.
