778942 - set resolution as builder user before buildbot starts

Status: RESOLVED FIXED

(Infrastructure & Operations :: RelOps: General, task)

Description

[Dustin J. Mitchell [:dustin] (he/him)]

Running 'screenresolution' doesn't work before anyone is logged in, which means that it won't work while puppetizing a new host.

This *might* be able to work in puppet when it is not puppetizing, if we're lucky enough to run puppet after the autologin has completed.  I'd prefer to run this as part of the buildbot startup process, though.  At that point, we know the builder user is logged in, and we're running in the correct context.

C.f. bug 712206.

OK, well, this *does* seem to work as root, once the user is logged in, and puppet will retry if it cannot set the resolution because the automatic login has not proceeded.  We only need to exclude this during puppetization, which is easy since there's a $::puppetizing fact.

So, this will do for now, and if the timing turns out such that this fails, then we can revisit.  We'll get error emails in that case.

I named this screenresolution::talos in case we later want screenresolution::builder or screenresolution::maximum or something like that.
