I have set (and double-checked) my notifications to appear in the bottom-right corner, just as I had it in Plasma 5.x where this issue never happened (as far as I can remember).
Seemingly randomly (I can’t find any pattern to reliably trigger it), one of the notifications instead appears in the top-left corner! How can that be?
It even sometimes shows a couple of notifications in the bottom-right part but then one in the top-left at the same time, instead of all three in the bottom-right.
At first, I thought that maybe it had to do with the “priority” of the notification, but that wasn’t the case.
My notifications are all in the bottom left, unless a specific application does something different…
You should provide a much more informative explanation of this issue… and confirm whether the same issue occurs using Wayland too, custom rules can interfere and sometimes themes and layouts can cause issues.
You can test it with:
notify-send "Test Notification" "This is a Plasma 6 notification test."
Is KDE Plasma the only desktop you ever installed on your system? having a penchant for mixing and matching (GNOME/Cinnamon or whatever) then a lot of desktop functions can be hijacked and messed up.
The upgrade from Plasma 5 to Plasma 6 was also a very major one, requiring a great deal of intervention and cleaning up…
This also links into a KDE Bug Report from August 2024 (as you’re using Debian, you might just be catching up a year later…). Perhaps a temporary fix involving kscreen2…
Posting the output of inxi -zv8 would be helpful for some of the boffins in the forum too
Well, all of the notifications I’m talking about are ones sent by my own scripts with notify-send "Test Notification" "This is a Plasma 6 notification test.".
As for Wayland, I can’t easily test in it because I’d have to turn off everything and log out and log in again. Wayland has so many problems that it becomes a pain to use the computer at all with it. But why should the “graphics mode” have anything to do with how Plasma decides to place notifications?
As for “custom rules”, I have no such. I’m deadly afraid to touch anything exotic after 2+ years of using Linux full-time and repeating having to reinstall from scratch and even buying new hardware in desperate attempts to solve all kinds of problems, always assuming that I have “done something wrong” (which never actually turns out to be the case).
If I simply open a terminal and run the same notify-send command multiple/many times in a row, all of them show up in the bottom-right corner. The top-left ones have nothing “special” about them but happen several times a day at seemingly random times. Like I said, this didn’t happen in Plasma 5 with the same exact commands/code/setup.
Yes, Plasma 6 is the only DE on my system.
Debian 13 with Plasma 6 was installed “clean” – it was not an upgrade and I did not import any old config files full of cruft from 5.
inxi -zv8 outputs a wealth of personal information. Anything in particular that would be relevant for this?
For the record, I only have and use one monitor. The bug page seems to suggest that this is related to multiple screens.
This will drive me nuts if I have to endure it for another two years! (But please don’t tell me again about how outdated Debian is. I’m aware. I can’t use Fedora because it has no ESR Firefox, and at any rate I just don’t have the energy left to undertake such a move at this point.)
It has happened a number of times since I posted this, and still I can’t see any pattern. It seems truly random. Is there some way to avoid this happening?
I can further add that I’ve tried it with both the “custom location” and “Near notification icon” settings, with the same result: it completely randomly and unpredictably displays the notification in the top-left corner, but mostly in the bottom-right corner. I only have one monitor. This bizarre glitch is torture…
It’s just a known bug. You’ll have to wait for someone to fix it, or change your system configuration to something that doesn’t encounter the bug (i.e. the Wayland session).
