I’m on a local system, it’s just my daily work laptop; like I said, it just happens at the login screen, not in /etc/passwd, and I can correctly login with both displayed options (I don’t know if I’m clear enough, it seems to be a duplicate display of the same item, not a duplicate item itself).
It happens now with Plasma 5.8 and it happened before with previous versions, and doesn’t seem to affect functionality of the system at all.
On the system that i clean-installed two days after the official release i had duplicated display icons on kde’s task bar after i changed the display language and adjusted localization to a different than the default. The removal of one of the two icons was not possible.
I had this issue on Leap 42.2 KDE.I didn’t see that this issue is on Tumbleweed.
I apologize for that. If the moderators think that this post does not belong here please remove it where else
Regarding the original problem: I just had a quick look at SDDM’s source code, and it just seems to read the entries from the /etc/passwd file via the standard system functions.
So I don’t really see how a duplication could happen there, unless they are already duplicated in /etc/passwd…
Though according to the getpwent() man page, it may get users from NIS or LDAP as well.
Unfortunately I have absolutely no experience with this, so I have no idea what could be wrong either.
Try to change them accordingly, i.e. remove the “files”. I suspect that having “compat” and “files” as source would result in reading /etc/passwd twice or something like that.
Strange though that what you have is actually the default in Tumbleweed. So if that’s the problem, it should happen on every TW system. So there must be something else playing a role here too… :-/
