 Posted: Thu Jul 27, 2017 11:21 pm Post subject: user-manager in plasma desktop not populating users |
 |
|
As the topic states, when the user manager in Plasma desktop is launched, it does not list the users on the machine.
There were some bug reports for fedora, but they were listed as fixed. I'll report as a bug if others can confirm, unless someone has a workaround.

I experienced something similar earlier this year. It is a bug in KDE Plasma 5, similar to -- or the same as -- the bug https://bugs.kde.org/show_bug.cgi?id=336994
I tried the work-around given in Comment 9 of that bug report:
| Code: | $ qdbus --system --literal org.freedesktop.Accounts /org/freedesktop/Accounts org.freedesktop.Accounts.CacheUser fitzcarraldo
[ObjectPath: /org/freedesktop/Accounts/User1000] |
That resulted in my user account being visible again in 'System Settings' > 'Account Details'. If I log out or reboot, the user is still visible in 'System Settings' > 'Account Details'.
Is that what you are experiencing?

Yes. This works, HOWEVER, if I try to make a change, it seems to clear the cache.
Example:
Pick a new avatar, click apply.
I get two dialogs asking for root privileges. One to make the change, the other to add the change to sddm. If I do this, my user name is wiped from the user manager again.
Also, the last portion of the command you provided:
| Code: | | [ObjectPath: /org/freedesktop/Accounts/User1000] |
resulted in | Quote: | | Invalid number of parameters |
. I pasted the whole line replacing your user name with mine. It worked fine when I did not use the portion after the user name.
Thank you!

You're welcome.
The second line I posted:
| Code: | | [ObjectPath: /org/freedesktop/Accounts/User1000] |
is not part of the command, it is the output resulting from the command on the first line (there is a carriage return after the username). I suppose I should have made that clear, but I posted the output so that you could see what the command would generate in the terminal. Anyway, glad that it (partially) solved your problem.

Can you confirm on your side that changing the avatar wipes the user info from user-manager?

Yes. It's a bug in KDE (see link in previous post). Unfortunately we have to wait until the KDE developers fix it.
EDIT: If you run System Settings from the command line you can see that User Manager does not work properly:
First I log in under my user account (fitzcarraldo, UID 1000), launch System Settings and see that the main user (UID 1000) is not shown in the User Manager GUI:
| Code: | fitzcarraldo@clevow230ss ~ $ systemsettings5
true
log_user_manager: "org.freedesktop.DBus.Error.ServiceUnknown" "The name org.freedesktop.login1 was not provided by any .service files"
fitzcarraldo@clevow230ss ~ $ |
So I list the users by using the following QDBus command in a Konsole window, and it indicates only the other user's account (brian, UID 1001):
| Code: | fitzcarraldo@clevow230ss ~ $ qdbus --system --literal org.freedesktop.Accounts /org/freedesktop/Accounts org.freedesktop.Accounts.ListCachedUsers
[Argument: ao {[ObjectPath: /org/freedesktop/Accounts/User1001]}]
fitzcarraldo@clevow230ss ~ $ |
So I use another QDBus command to re-add the missing user (fitzcarraldo, UID 1000):
| Code: | fitzcarraldo@clevow230ss ~ $ qdbus --system --literal org.freedesktop.Accounts /org/freedesktop/Accounts org.freedesktop.Accounts.CacheUser fitzcarraldo
[ObjectPath: /org/freedesktop/Accounts/User1000]
fitzcarraldo@clevow230ss ~ $ |
Then I use the QDBus command to list the users, and it now lists both users:
| Code: | fitzcarraldo@clevow230ss ~ $ qdbus --system --literal org.freedesktop.Accounts /org/freedesktop/Accounts org.freedesktop.Accounts.ListCachedUsers
[Argument: ao {[ObjectPath: /org/freedesktop/Accounts/User1000], [ObjectPath: /org/freedesktop/Accounts/User1001]}]
fitzcarraldo@clevow230ss ~ $ |
So I launch System Settings again and try to add an avatar to user fitzcarraldo (UID 1000) via the User Manager GUI:
| Code: | fitzcarraldo@clevow230ss ~ $ systemsettings5
true
log_user_manager: "org.freedesktop.DBus.Error.ServiceUnknown" "The name org.freedesktop.login1 was not provided by any .service files"
No file found for ".xml" , even though update-mime-info said it would exist.
Either it was just removed, or the directory doesn't have executable permission... ("/home/fitzcarraldo/.local/share/mime", "/usr/share/mime")
log_user_manager: Starting: QUrl("file:///home/fitzcarraldo/Pictures/Avatars/Fitzcarraldo.png")
log_user_manager: From: QUrl("file:///home/fitzcarraldo/Pictures/Avatars/Fitzcarraldo.png") to: "/tmp/systemsettings.FW8131"
log_user_manager: Avatar created
log_user_manager: Saving on Index: 0
log_user_manager: "org.freedesktop.DBus.Error.UnknownMethod"
log_user_manager: "No such interface 'org.freedesktop.Accounts.User' on object at path /org/freedesktop/Accounts/User1000"
log_user_manager: "org.freedesktop.DBus.Error.UnknownMethod"
log_user_manager: "No such interface 'org.freedesktop.Accounts.User' on object at path /org/freedesktop/Accounts/User1000"
kf5.kauth: Tried to start an invalid action
fail "Tried to start an invalid action"
log_user_manager: "org.freedesktop.DBus.Error.UnknownMethod"
log_user_manager: "No such interface 'org.freedesktop.Accounts.User' on object at path /org/freedesktop/Accounts/User1000"
log_user_manager: Failed Roles: (AccountModel::Email, AccountModel::Administrator, AccountModel::AutomaticLogin)
fitzcarraldo@clevow230ss ~ $ |
User fitzcarraldo has disappeared from User Manager in Systems Settings, and you can see from the error messages above that User Manager did not work correctly.

OK, I've been playing around with this KDE and freedesktop.org mess and have a work-around, at least in my situation (LightDM 1.18.3 with the patch in Gentoo Bug Report #605370 for non-systemd installations with the LightDM GTK Greeter, and KDE Plasma 5.9.5):

My patch for LightDM 1.18.3 is probably irrelevant as far as this KDE Plasma 5 User Manager mess is concerned, but I mention it just in case.
Although I use LightDM, included in the steps below are addtional steps I think are necessary for SDDM, although I believe they are irrelevant in my case.
1. I created a 96x96 PNG avatar /home/fitzcarraldo/Pictures/Avatars/Fitzcarraldo.png
2. I edited the file /var/lib/AccountsService/users/fitzcarraldo to contain the following (replace 'en_GB.utf8' with your language)
| Code: | [User]
Language=en_GB.utf8
XSession=plasma
SystemAccount=false
Icon=/var/lib/AccountsService/icons/fitzcarraldo |
3. I made sure that file has 644 permissions
| Code: | clevow230ss fitzcarraldo # ls -la /var/lib/AccountsService/users/fitzcarraldo
-rw-r--r-- 1 root root 104 Aug 5 16:43 /var/lib/AccountsService/users/fitzcarraldo |
4. I copied the avatar to the relevant directory and made sure it has 644 permissions
| Code: | clevow230ss fitzcarraldo # cp /home/fitzcarraldo/Pictures/Avatars/Fitzcarraldo.png /var/lib/AccountsService/icons/fitzcarraldo
clevow230ss fitzcarraldo # ls -la /var/lib/AccountsService/icons/fitzcarraldo
-rw-r--r-- 1 root root 12667 Aug 5 16:23 /var/lib/AccountsService/icons/fitzcarraldo |
5. I also copied the avatar to ~/.face.icon (possible SDDM requirement, I believe)
| Code: | | fitzcarraldo@clevow230ss ~ $ cp ~/Pictures/Avatars/Fitzcarraldo.png ~/.face.icon |
6. I edited /etc/sddm.conf and changed the path of FacesDir as shown below
| Code: | # Face icon directory
# The files should be in username.face.icon format
#FacesDir=/usr/share/sddm/faces
FacesDir=/var/lib/AccountsService/icons/ |
7. I rebooted (logging out is not sufficient).
I now have the avatar Fitzcarraldo.png on LightDM's GTK Greeter screen, on the KDE Plasma 5 Lock screen, in 'System Settings' > 'Account Details' > 'User Manager', and at the top of the KDE Plasma 5 Application Launcher menu.
I recommend not using 'System Settings' > 'Account Details' > 'User Manager' again until the bug is squashed, but you can try copying the avatars of other users to /var/lib/AccountsService/icons/ and editing the other users' files in /var/lib/AccountsService/users/ as I explained above, to see if you have any success, but I would leave things alone.
EDIT1: I have always used app-admin/superadduser on the command line to add new users, and it's never failed me. I have just now used it to add a new user, and then I manually repeated the process I described above. The avatar of the new user is displayed correctly everywhere it should be, and my own account's avatar is still displayed everywhere it should be. So you can achieve what you want without touching 'System Settings' > 'Account Details' > 'User Manager'.
EDIT2: Regarding Step 6 above, I think the avatar used by SDDM in FacesDir has to be named fitzcarraldo.face.icon so, for SDDM users, I would add an addtional step:
6.5. Make a copy of the avatar for use by SDDM in $FacesDir
| Code: | | clevow230ss fitzcarraldo # cp /home/fitzcarraldo/Pictures/Avatars/Fitzcarraldo.png /var/lib/AccountsService/icons/fitzcarraldo.face.icon |

My curiosity having been well and truely piqued, I've been investigating further. Another thing to try is to launch System Settings with the root user's permissions, i.e. using kdesu5:
| Code: | | $ kdesu5 systemsettings5 |
If I do that, a user who is not shown when System Settings is launched either via the KDE Application Launcher or via the systemsettings5 command alone does appear in the 'User Manager' GUI.

I tried the above before making the changes you suggested, and it did not work.
Your suggestions are a workaround for the bug currently, so thank you for that!

Latest update on KDE bug report 336994. Comment 27 states:
| Valeriy Malov wrote: | There seem to be multiple separate issues
On Gentoo in particular AccountsService seems to be broken because of /etc/passwd and /etc/shadow mismatch on "old" installs: portage user is sometimes missing from /etc/shadow but is present in /etc/passwd. This causes AccountsService to go haywire. This can be fixed (back up your stuff beforehand) by regenerating shadow with pwconv. I'm not sure if /etc/shadow can be considered malformed in this case or it is worth reporting to AccountsService bugtracker.
Another problem is that we accidentally overwrite first item in the model when polling AccountsService via dbus with currently logged in user. This causes some other user to disappear from the list. If anyone wants to review the patch: https://phabricator.kde.org/D12837 |
