I am running Ubuntu Studio 21.10 on Kernel Version 5.13.0-2-lowlatency (64-bit);KDE Plasma & Frameworks versions are 5.22.5 and 5.86.0, respectively. Qt is version 5.15.2.

The system is AMD w/ 8 GB RAM.

I don't recall doing anything to tell magnus to pop up and annoy me each time I log in.

It is not in the usual "Startup" system setting dialog.

I'm unaware of other "startup" settings where it may be hiding.Do you know where/what I need to modify to prevent this tool from popping up without being requested.

    Does uninstalling the program ok?

    A stock install of Magnus (screen magnifier) will autostart. The reason is not documented, but one imagines it's to avoid the chicken-and-egg problem of a visually-impaired user unable to see how to launch it. Run dpkg -L magnus to see where all the Magnus files are located. Find the location of the file magnus-autostart.desktop. Edit that desktop file to disable autostart.

    @user535733: Can you promote your comment to an answer? Also, the fact that the user isn't provided with clear instructions about what magnus is, why it autostarts, or how to disable it, is, IMO, a bug.

  • @MRule I would gently suggest that it's design decision, perhaps one that you feel introduces a usability papercut. In this case, only Ubuntu Budgie and Ubuntu MATE are affected. Both are community-driven flavors of Ubuntu -- you can get involved and solve that papercut.

    I'm not saying that Magnus shouldn't be there. I'm saying that introducing a new, unexplained autostart program --- with absolutely no information about what it is, why it autostrats, or how to turn it off, is a bug in the documentation and/or on-screen information accessible via magnus on first encounter.

Straight up removing the file solved the issue.

sudo rm /etc/xdg/autostart/magnus-autostart.desktop
