gpu_init.cc Passthrough is not supported, GL is disabled

• This issue is blocking
• This issue is causing unreasonable pain

I haven’t run darc in many months, but today I needed to, so pulled main (6d47939a55dde813), ran .\eng\common\darc-init.ps1, followed by darc authenticate.

For some reason, I got this error on my physical machine during the authenticate:

[4184:1015/103136.034:ERROR:gpu_init.cc(440)] Passthrough is not supported, GL is disabled

The editor opened, I entered my tokens, saved/closed, then the error appeared after 30 seconds or so.

On a VM I have, I performed the same steps, using the same tokens, and it worked immediately.

Has this issue been seen before? From a quick web search, it sounds like it often occurs due to some Chromium driver issue, but I don’t understand how that would be related to darc.

I just tried a darc authenticate and for whatever reason, today I’m not getting that error. Sounds transient and external, so I’ll close. Thanks!

That makes a lot more sense, now, as to why Chromium drivers may be in play. On my machine that repro’s the issue, it’s VS Code, which is an Electron app. ......Microsoft VS Code\Code.exe" --wait

However, when I run the same command (with the same path and arguments), VS Code opens just fine. Does DARC not support VSCode as an editor, or is there a new bug? I have had this configuration for years, and definitely used DARC before without the error.

I use VSCode as an editor for darc, It’s just using your core.editor for git, which I have set to:

PS C:\r\runtime> git config --list | findstr -i code
core.editor="C:\Users\mmitche\AppData\Local\Programs\Microsoft VS Code\Code.exe" --wait

It does show error and odd messages from time to time, but darc itself knows nothing about vscode.
