Doesn't work on Fedora 23 with Gnome 3.18

[heis2201]

libgtop2 is installed. Installing this extensions gives an unspecified error.

Hi @heis2201, What do you mean by unspecified error?

Can you open a terminal and run journalctl -b -f in there. After that try to install it again. Paste the errors you got from the terminal here.

[heis2201]

Error is reproducable. So, here is the output of journalctl -b -f:

@heis2201 Sorry, but these errors mean nothing to me. I don't see how it's connected to this extension.

I suggest you to report this problem to the Gnome developers at https://bugzilla.gnome.org/.

But before that you might want to disable all other extension first and try to do the installation again. If it works, then some other extension is incompatible with this one, otherwise it's probably a bug in one of the Gnome components.

I had the same problem with a Debian stretch. I solved it by installing lm-sensors. Somewhat installation of system-monitor does not ask for it but it does seem to need it! So heis2201, try installing that before you reinstall system-monitor. Best

[heis2201]

Hi already have lm_sensors installed. That didn't fix it. But thanks anyways.

I have similar symptoms on Ubuntu. I'm trying to run from master branch commit 20d87db.

Tweak Tool says "Error loading extension."

LookingGlass says "System_Monitor@bghome.gmail.com has not emitted any errors."

journalctl shows:

 1月 30 11:15:01 gnome-session[2879]: (gnome-shell:2944): Gjs-WARNING **: JS ERROR: Exception in callback for signal: extenson-found: Error: Requiring GTop, version none: Typelib file for namespace 'GTop' (any version) not found

So it seems like this is a libgtop dependency problem, but it looks to me like I have the required dependencies:

Update

The extension started and works fine after I installed the libgtop2-dev development package

$ sudo aptitude install libgtop2-dev

@jamesdbrock Thanks for letting us know. I've updated the installation wiki page.

[skyghis]

Installing sudo apt install gir1.2-gtop-2.0 is enough on Ubuntu 17.10 to fix the error.
