I'm using pop_os with Wayland and I was wondering whether there was a way to remove certain processes from the Alt-Tab menu.

In my case I have a certain gjs process @!0,28;BDH which appears in my Alt-Tab menu and I would like to get rid of it.

Try finding out who is making that window, process is wrong word I guess, alt+tab show open windows. Say ps aux | grep gjs in terminal or search it in Gnome System Monitor or htop and kill it, but check if it is some thing important. Or wmctl -l to find the window id and kill the window with xkill.

  • Hey, thank you for reaching out. I have already tried to kill it by using system monitor but it doesn't work, it just restores itself. I think it's a wayland thing, so as long as i use wayland it'll just come back up. Simply killing it doesn't seem to work, so i was looking for a way to hide it from alt tab at least.

  • i tried that, problem is that gjs is not listed in wmctrl. I think the os sees it as an underlying background program and not as a window. This is the output i get when compiling wmctrl -l and you can see gjs is not listed although i can see it on alt tab 0x01800005 0 pop-os organizer5.py - Programs - Visual Studio Code 0x00a00002 0 pop-os xubuntu - XFCE: Hiding an application from the taskbar - Ask Ubuntu - Google Chrome Commented Jul 29, 2021 at 10:34
  • That's odd, in my system, KDE Plasma (Kwin WM), it even lists root windows, marked -1, 0x02000042 -1 artix Plasma Commented Jul 30, 2021 at 5:02
  • I know right? Even when i use the searchbox it shows the windows wmctrl sees, that means gjs is not showing, it's only present in the Alt-Tab menu Commented Jul 30, 2021 at 12:03
