[dreua]

Thanks!

Can you run gnome-extensions listfor me?

[dreua]

1. And maybe gnome-extensions enable [email protected] just works?
2. Have you done a reboot since installing the extension and tried again? (Or restart X via Alt+F2, r, enter)
3. Are you using X or Wayland?

[Jerther]

Sure thing.

$ gnome-extensions enable [email protected]

Extension “[email protected]” does not exist

I haven't tried a reboot yet. Will do after this post.

Using Wayland

[Jerther]

No way.... I rebooted, did gnome-extensions enable [email protected] and the thing started...

Having to reboot was the usual thing to do back in 1997 but it has become a rare thing in late years. I think I may have become a bit spoiled ;)

By the way I really did a reboot. I did not try to log out and back in but that might have worked too and it would make sens.

[dreua]

Meh, so this is another one of the Wayland hurdles. I'm still with X by the way... You are right, reboot should not be necessary but at the end of the day, it is the way to make absolutely sure that everything is reloaded. With X Alt+F2, r works fine, I don't know the equivalent Wayland commands unfortunately.

[Jerther]

Well I don't install this extension every day so I can live with that.

For now... ;)

Should I close this issue?

[dreua]

Yes, this issue sounds closed to me.

Wayland/Gnome really needs a better way to handle this but that is another topic, not specific to the system-monitor-applet. Happy monitoring! :tada:

[p91paul]

@dreua there is not an equivalent unfortunately. alt-f2+r just doesn't work, and apparently there isn't a way to make it work.
AFAIK with X your windows, and gnome shell itself, all use X for drawing, so you can restart the gnome-shell process without killing everything else.
With wayland instead the shell also acts like a compositor for all other windows. So there is no way to safely restart the shell without also killing all of the user processes.

My explanation is probably quite inaccurate because I don't have a very good understanding of neither wayland nor X, but that's what I got when I was googling how to restart the shell on wayland a while ago. It's a PITA when you are debugging extensions.

[dreua]

@p91paul I think you got that right, I also understand it like you said. I'm wondering: Is it to be fixed in Wayland or in Gnome? Any open Bugs already?

[p91paul]

@dreua I believe it's in gnome, they would need to implement a way to reload extensions without restarting the whole gnome-shell process.

Apparently it was reported, but closed without leaving hope for a fix.
