Clearing crashed apps from the desktop

[Kenna]

I have to use the open source app Qgis for my university study. My lecturer says that it's a good program but occasionally crashes in Windows, requiring a reboot. The Linux version does the same for me in Zorin 18 & 18.1 Pro with 64M of RAM. It just freezes with no response at all to the mouse, although the mouse will move over it OK.
I'd rather not have to reboot unless absolutely necessary.
Is there a way to clear the crashed app from the desktop? I'd rather not use terminal, but if that's the only way, how do I do it there?

If you press alt+F2, then enter in

lg

That is lg for Looking Glass

Then in the Looking Glass GUI, select the Qgis Window > Force close, does that kill the process?

I always use xkill which I have bound to a keyboard shortcut - but Wayland does not support xkill...

[Kenna]

Looking Glass is just what I'm after! Thanks!

I'm still very new to both Linux and Zorin, so is there an easy way to create icons for Run a Command and/or lg and get them to appear in System Tools or Utilities? (I still can't predict in which of these I'll find utility apps that I might be looking for.)

[Aravisian]

Looking Glass is built into a program and this is kind of a thing... Some software is not its own independent software, but a portion of a larger stack. So it cannot be isolated and targeted in the same way that software is.

Fortunately for you, I think these two can be anyway.

@Kenna

Run a Command

This is invoked with alt-F2
And LG - you know already... If you want them in the App Menu:

You can create a .desktop file and place it in ~/.local/share/applications just for the user... Or in /usr/share/applications for system wide.

By the way - you can alter the contents of existing .desktop files if you want - say you want GIMP to be shown in "Games" category for some reason that only you would understand...., in the .desktop file change category to 'games'

For alt_f2 Run Command:

[Desktop Entry]
Name=Run
Comment=Open GNOME Alt+F2 command prompt
Exec=sh -c "gdbus call --session --dest org.gnome.Shell --object-path /org/gnome/Shell --method org.gnome.Shell.Eval 'Main.openRunDialog()'"
Icon=system-run
Terminal=false
Type=Application
Categories=Utility;

For LG:

[Desktop Entry]
Name=Looking Glass
Comment=Open GNome Shell Looking Glass debugger
Exec=sh -c "gdbus call --session --dest org.gnome.Shell --object-path /org/gnome/Shell --method org.gnome.Shell.Eval 'Main.createLookingGlass().open()'"
Icon=utilities-terminal
Terminal=false
Type=Application
Categories=Utility;

The Name= part can be safely changed. Like... if you want to call "Looking Glass" something else, like "Inspectaholic" or "ISeeYouNavi"...
Comments can be changed - that is what displays as its Hint Tip

I agree about xkill:
Log out and select "Zorin Desktop on Xorg" from right bottom setting icon. (But if it says zorin desktop on wayland, then select the version Zorin Desktop)

Then open settings:

This way when you click on a window, it's gonna terminate it immediately.

I also use Xorg. It is mature and stable. Wayland is not yet ready for public use, despite it being pushed so heavily onto us.

But - a note: @Kenna, the above is a suggestion - not a requirement. If you prefer Wayland, you would need to ignore the suggestion.

Thanks. I've not seen any issues that I could attribute to Wayland, so I'll leave well enough alone. I've never used x11 so I've not even an idea of what to look for.

I don't know if someone can prefer Wayland (no gain just pain), It's like sitting on billions of needles...
