Following the previous discussion [1] and the gathered support, here's a proposal for the user switching criterion. I believe we should put it into the Final milestone [2]. ~~~~~~~~~~~~~~~~~~~~~ User switching User switching must work using the mechanisms offered (if any) by all release-blocking desktops in their default configuration. What is user switching? User switching is a process of changing the currently presented desktop session between concurrent sessions of two or more different users. The user sessions keep running in the background, and users can switch between them repeatedly without losing any running application state. For the purpose of this criterion, user switching doesn't include switching between different sessions of the *same* user. Work? The switching mechanism must correctly attempt the requested operation. If the operation doesn't work on a subset of graphical drivers, the release blocking decision should be based on the number of affected users, the problem severity and available workarounds (as is our [standard procedure](Basic_Release_Criteria#Basic_Release_Requirements)[3]). ~~~~~~~~~~~~~~~~~~~~~~ The "in their default configuration" part is there to cover only cases where the system hasn't been modified in a substantial (and relevant) way. This will exclude cases where people e.g. install several desktop environments, replace their DM for a different one, tweak systemd settings, or install a non-default graphics driver. In the last paragraph I explicitly pointed out that we'll use our usual approach of judging the impact if the issue only affects certain configurations. I hope that alleviates some hardware-related concerns. Note: I considered the option to also include user switching in text-only environments (simultaneous user login on different VTs, as is common on Server), but it's not completely the same. I concluded it's better to have a separate and tailored criterion for it, if there's interest. Please comment, thank you.

I think we don't need the weasel form in this criterion as we actually do want to block on user switching *fully working*. So I think I'd agree with Lukas (and Brandon) that this can be changed to "perform", but keeping the reference to conditional violations if you like - but I'd change the link to this part of the blocker bug FAQ: https://fedoraproject.org/wiki/Blocker_Bug_FAQ#What_about_hardware_and_lo... which is what we usually use as the target for such references.
