Hello World,
By using the system settings you can choose the position where notifications appear but only in a basic way. 
However I would like to keep it in that corner, but be able to modify it’s Y position too, to put it a bit higher, otherwise… well you can see my problem when I have OSDlyrics turned on in the pic. So is there any way I can do that?
Thank you.
I don’t know which desktop you use, but maybe you have to put a little work in your used theme?
Oh sorry, my bad, so KDE Plasma with Expose Air theme that I have made some modifications over the time.
Although I’d be lying if I said I remember exactly what I did to it, but the window decorations is set to Breeze theme and the plasma style to Expose Air for example.
You could try disabling Plasma notifications and using a DE-agnostic notifier instead.
This is how my Cinnamon is set up to use Dunst. When searching for docs to do this, especially the Arch wiki, they told me it’s not possible. Yet here I am with Dunst notifications in Cinnamon. So, it may be possible in Plasma as well.
Built-in
Cinnamon, Deepin, Enlightenment, GNOME, GNOME Flashback and KDE Plasma use their own implementations to display notifications, and it cannot be replaced. Their notification servers are started automatically on login to receive notifications from applications via DBus.
Arch Wiki: https://wiki.archlinux.org/title/Desktop_notifications
The process is to find out what disables Plasma notifications, then set Dunst to autostart.
Example:
gsettings set org.cinnamon allow-other-notification-handlers true
Oh, interesting… Ok I’ll play with this tomorrow and let you know what I manage to destroy. 
for anyone else reading it is DE-specific:
cinnamon: no
budgie: yes
lxde: depends on sun and moon and stars
etc
For anyone else reading, this guy did not read/understand my post. 
Cinnamon: needs a simple command (See above)
Budgie: probably the same as Cinnamon (See above)
LXDE: See above…
Etc.
just responding to title question. I do plead guilty to not reading every post in this one and for that you caught me red-handed and sheepish.
but.
still I can’t pick my notification corner in cinnamon. (I asked this recently in a thread)
I can pick my corner in budgie.
lxde: act of god
Well, yes, the default Cinnamon experience limits what you can do. But because I use i3 and Openbox mostly, I ended up getting used to the customization they provide, and very used to using Dunst for notifications.
So, I searched the webs and ended up finding out how to use Dunst in Cinnamon, since it’s my “backup DE”, and seeing Cinnamon notifications threw me off whenever I used it.
Long story short: This is Linux. Almost anything can be achieved.
I’m not a developer, by the way. I’m just really good at web searching.
not to hijack but the magic of Dunst and Picom is incredible. Have used them both. Just enough configuring to keep me away from WMs and with a conventional DE
