App icons dissapeared / whisker menu

Hi,
don’t know what i did.

In the whisker menu the whole category “internet” disappeared.

Also some icons/apps from “all applications” disappeared.
Which are: firefox, chromium, thunderbird, filezilla. (maybe more).
There’s only this “start firefox” icon (2 little gearwheels),
when i type the whole app name.

Also browsing the internet became veeery slow,
with both ff and chromium.
Also Thunderbird is slow in connecting the mail servers.
On another tablet computer internet is fast as usual.

Does this issue persist if you create a new user and log in there? (E.G. haines2)

:thinking:

All the app icons and the “internet” category are there.
But the internet speed is still slow…

Also, this menu has a manjaro icon in the new user.
Here, in the weird situation,
this menu has a symbol of a mouse head, i guess…

I can’t help you with that and no one can until you create a new topic all by itself for this issue and post much more information:man_shrugging:

So you have an issue in your user profile and finding out which exact setting you changed is going to take weeks if not months, therefore, we’re going to do the following:

  • Verify that the new user has access to the same groups as your old one by executing groups and comparing the output of both users.

    groups twitty
    groups twitty2
    

    (Where obviously, twitty is your old user and twitty2 is your new one.)
    E.G. if twitty is a member of operator and twitty2 isn’t, execute:

    usermod --append --groups operator twitty2
    
  • Copy all data files from your old profile into your new one

    cp --verbose --recursive --preserve=time-stamps /home/twitty/Documents/* /home/twitty2/Documents/
    

    If that worked and you had no errors, remove the documents from your old user:

    rm --recursive /home/twitty/Documents/*
    

    repeat for:

    • Pictures
    • Videos
    • Music
    • .thunderbird
    • .mozilla/firefox/
    • Templates, and everything else that is important to you.
    • Linux games like Battle of Wesnoth have their game data stored under ~/.local/share/ E.G. ~/.local/share/wesnoth/

    After everything has been copied over, disable the old user so you cannot accidentally log on:

    usermod --lock twitty
    

    If you would have theming going on, don’t do everything in one day but do this at the rate of 1 application / theme / whatever per day and if the same issue crops up again, roll back your last change and thus you’ve now pinpointed the exact setting that made your old user misbehave. :thinking:

  • in 1 month delete the entire home directory of your old user, but don’t delete the user itself so that in 6 months time files still owned by that user will still show up under its username.

  • If you ever migrate to a new machine, just don’t migrate the old user: only the new one.

  • From now on, start making backups so you can roll back and never have to do this again:

Both, old and new user, were in exactly the same groups…

But first, thanks for your detailed and comprehensive reply.
Got a lot to think about from it.

After ducking a while around i found the solution.
I found menulibre (using with -v option) which said, the “internet” category was hidden.
So i reversed that.
It also said, that there was apparently an faulty entry in org.kde.kded5.desktop
which i corrected.
Now everything is fine again, and even the web page loading is fast again.

Thanks a lot.
