Notifications in the middle of the screen

Hi everyone,

Notifications appear in the lower middle of the screen no matter what the applet settings are.
Probably not the same bug as 481736 – On X11, Notifications pop up in the middle of the screen after being away from pc for a while - happens all the time, not only after monitor sleep.
Started happening after updating to 6.2.4 on Neon.
Using X11 with Nvidia driver.

try this, maybe it helps

As he stated, he probably did that.

Hi - I do wonder if there is some underlying shared cause between what you’re seeing, and what’s described in that bug report, which might be triggering the “right” conditions even without the monitor going to sleep.

Does adjusting the size of the Plasma panel back and forth by a pixel correct the issue, even if temporarily?

Yes, already tried setting notification location without success. No matter the setting, the popup appears on the same place.

Resizing the panel and back did not help either.

I’ve checked man notify-send and skimmed through the 9 pages of Desktop Notifications Specification but did not find anything related to x/y position nor window placement.

Hmm - a couple general troubleshooting steps might be helpful to at least rule things out. Could you try:

  • Creating a new user account, and seeing if the issue shows up in that account? (To rule out an issue with the specific configuration files and settings for that user)
  • Checking the system journal (logs) after the issue occurs to see if any errors related to the display, shell, notifications, etc. specifically show up when it happens? Running sudo journalctl --since=-1m would give you all of the journal entries in the past minute, which may hold some clues?
  • Logging in to a Wayland session to see if the issue occurs there?

Thank you for the suggestions. Here are the results:

  • Creating a new user account:
    Everything fine, notifications appear next to the tray icons.

  • System logs:
    Nothing in journalctl and ~/.xsession-errors.

  • Wayland session
    Couldn’t start, black screen and the screen backlight flashes on-off.

Edit: fixed Wayland session with:
options nvidia_drm modeset=1
options nvidia_drm fbdev=1

Notifications appear where they should - next to the tray.
