Startup won't run latte-dock

So here’s the thing.
Startup works fine, tried with Firefox.
Enabling startup through the app places it in the startup menu but does not work.
Changing the command from “latte-dock &u” to “latte-dock & disown” does not work.
(i am new to Linux but i noticed that &u closes the program when you quit the terminal so i thought that might be it.)
Reinstalling does not work although upon reinstall it kept my configuration so maybe whatever caused the problem stayed with me.
In a previous install of leap 15 that i ****ed up (read new user should not config what he does not understand) startup worked fine.
Installed through terminal first time second time through the software center
So if you have any ideas or know of a way to completely remove and do a fresh reinstall that would be grand

Cheers

Completely removing an app isn’t always assured.

You can do any combination of the following…

If you want to know what was installed in your machine,
Install the package again or in a throwaway virtual machine (Virtualization is great for things like this… You can use them for testing and then throw them away without affecting your real, physical machine)
Then run the following to display the contents of that package

rpm -ql *packagename* 

Or, from what you have now…
After uninstalling the package which can leave remnants in your system,
Install the locate utility which is part of the mlocate package

zypper in mlocate

After installation, the locate database updates every 24 hrs automatically but we don’t want to wait a day before first use, so run the following to populate the database

updatedb

Now you can quickly search your system for any files and directories.
I’m going to guess that “latte” is a pretty unique word that can only be related to the app you just removed, so the following will display all directories and files with “latte” as part of the name

locate latte

If what you see look like they’re related to the app you’re trying to purge, then manually delete them.

HTH,

I figured it out. If there is a notifications widget on the dock while another one exists anywhere it won’t open on startup.
Still this information seems valuable and for that i thank you.
