Bug 1999060

Just a confirmation that this bug is also reproducible on RHEL-9.0 with anaconda-34.25.0.25-1.el9.

I was able to reproduce this bug on newest RHEL 9.0 GA (2022-05-05) with anaconda-34.25.0.29-1.el9_0 and on other OS built from code of RHEL.

Hello GNOME, this is probably something on your side of the stack. Quoting https://bugzilla.redhat.com/show_bug.cgi?id=1998460#c7 :

> After fiddling with this more, it appears that most of the assumptions Anaconda GUI made about modality etc. are no longer true. The list so far is:
> - in all GNOME-based environments, yelp starts maximized (but not under KDE)
> - on boot.iso under gnome-kiosk, yelp loses the title bar after unmaximizing (this very bug)
> - on boot.iso under gnome-kiosk, nm-connection-editor is not really modal with --keep-above, it merely stays on top

Can you please help us understand this?

Hi Ray,
could you please advise how to move forward with this problem? Is there an easy workaround for anaconda?

*** Bug 2132491 has been marked as a duplicate of this bug. ***

sorry i haven't tried to reproduce at all. anaconda is just running yelp ? can you provide a screenshot?

(nm on the screenshot, i've reproduced in a vm)

I think this commit should fix it:

https://gitlab.gnome.org/GNOME/yelp/-/commit/245c0936cd026f0cce5d9a63870a1fdfdbe4fab3

i just quickly tried it and it's not exactly working right even with that commit

gnome-kiosk patch that fixes this

So what's happening here is, gnome-kiosk isn't detecting anaconda as "the main app" because anaconda isn't making it's window go fullscreen when it goes fullscreen. Instead it's just going monitor sized.

gnome-kiosk then doesn't consider it the "main" kiosk application and promotes yelp to that.

The above patch changes the heuristic to pick up anaconda too, so yelp gets second class status as it should.

This could be fixed in anaconda too, I think, by making the anaconda window fullscreen.

Tried that just now with https://github.com/rhinstaller/anaconda/pull/4373. However, going fullscreen does not appear to change the behavior. 

Ray, is there some easy way to get a RPM with the patched yelp - I mean this from comment 12?

i could give you a scratch build with the commit you mention from comment 11, but like I said in comment 12, it's not really working right with that change either. gnome-kiosk is getting confused so it only works after closing and opening the window once (with ctrl-w). Would you like a scratch build of gnome-kiosk with the fix from comment 13 ?

gnome-kiosk scratch build started here: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=48216862

assuming it doesn't fail, it should be ready soon I think.

builders seem hung up so i did a c9s scratch build instead: https://kojihub.stream.rdu2.redhat.com/koji/taskinfo?taskID=1497774

Ray, thank you, this appears to resolve the issue!

(It's weird, why does this work and full-screening anaconda does not, but never mind...)
