--- Comment #8 from Adam Williamson <ad...@happyassassin.net> --- I think there's definitely an underlying bug here with the "Cannot write display number" messages. In Fedora openQA testing we're also getting frequent failures of the user switch test. I tried that out manually too, and saw the same issue - when I switch users, it takes a long time for the second user's session to start (so long that openQA gives up, but in local testing I found it *does* come up after a while). In the logs I see that error four times, then a message from kwin saying it's giving up on Xwayland after four tries - and indeed the second user's session has no Xwayland process. And, of course, sometimes I get at least some of those errors just logging in as the first user (which is when we see this notification). I tested an F41 install for comparison. There, on two attempts, user switching worked flawlessly, both sessions have an Xwayland process, and there were zero "Cannot write display number" errors in either user session on either attempt. So we should probably dig further into what's going on there, and how it's changed since F41. -- You are receiving this mail because: You are watching all bug changes.
