[bcmedeiros]

Same here on Arch

[epifanio]

same for me .. great extension, I am missing it <3

[hadim]

same here

[flauschzelle]

Same here...

I had to install it manually, because the gnome shell extensions browser plugins don't work any more with 22.04's snap browsers.

After a restart of the system, it looks like this in the gnome-extensions tool:

If I click on the "Settings" button, I get the following message. (The same message also appears if I run gnome-extensions prefs [email protected] from the command line.) I hope this contains helpful info for fixing the problem:

[epifanio]

just a side note .. I if I install and log-out then log-in .. the widget shows on the top bar and works as expected -- it then disappears at the next log-out -> log-in

[leillo1975]

I have the same problem. Please give support for Gnome Shell 42

[johnmee]

Yep, same here. Highly annoying. At first, I thought "No problem, the git repo is already on my machine, just need a quick pull and 'make install'".

Like you said, first log out/in gives you the extension you just installed, but if you bring up the Extensions app, you see that it'll be "updated" on the next login.

The good news is that the latest code does work on Gnome 42. So, most likely, just needs a proper release.

[philb61]

I had to install it manually, because the gnome shell extensions browser plugins don't work any more with 22.04's snap browsers.

FYI, Chrome (.deb from their repo) still works. One of the few reasons to still have it around, along with if you know anyone using Google Meet.

just a side note .. I if I install and log-out then log-in .. the widget shows on the top bar and works as expected -- it then disappears at the next log-out -> log-in

Not for me. Shows up every time after logout->login. Manual install of current master:

origin https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet.git
commit 02a590ee43187bf252cb21dbd278159d212e1f15 (HEAD -> master, origin/master, origin/HEAD)
Date:  Sun Apr 10 01:00:42 2022 -0400
GNOME Shell 42.0
Ubuntu 22.04 LTS
extension metadata "shell-version": ["3.26", "3.28", "3.30", "3.32", "3.34", "3.36", "40", "41", "42"],

PS: Sorry, by 'install' I thought you were referring to a manual install.

[diegolgz]

Simple fix until it's patched:

Edit file ~/.local/share/gnome-shell/extensions/[email protected]/metadata.json and add a comma after "40" in line 14 and add a "42" after line 14.

Restart gnome-shell (Alt+F2, r) and the extension should work as expected.

[e11bits]

Or even easier without any editing:

git clone https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet.git cd gnome-shell-system-monitor-applet ; make install

[leinardi]

Or even more easier, just install the "next" version of the extension: https://extensions.gnome.org/extension/3010/system-monitor-next/

This fork of paradoxxxzero/gnome-shell-system-monitor-applet is for packaging purposes only. This extension is built and updated continuously with the upstream master branch.

This is preferable for users on bleeding edge distributions that prefer not to wait for a stable release from the main repo. Of course, since we're releasing directly from master some instability is inevitable.

[diegolgz]

Or even more easier, just install the "next" version of the extension: https://extensions.gnome.org/extension/3010/system-monitor-next/

Sorry but that extension is not the official one, so I prefer either to install it from source, as stated by @e11bits, or edit the file until they release an official release.

Anyway, I appreciate your comment and effort :)

[laurentpayot]

Simple fix until it's patched:

Edit file ~/.local/share/gnome-shell/extensions/[email protected]/metadata.json and add a comma after "40" in line 14 and add a "42" after line 14.

Restart gnome-shell (Alt+F2, r) and the extension should work as expected.

@diegolagoglez Thanks a lot, it worked for me! :grin:

Same worked for me. I didn't have a line 14, but here's my metadata.json:

I get Tried to construct an object without a GType on Gnome 42, Ubuntu 22.04.

make sure you have required dependencies $ sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0 gnome-system-monitor

[flauschzelle]

I get Tried to construct an object without a GType on Gnome 42, Ubuntu 22.04.

make sure you have required dependencies $ sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0 gnome-system-monitor

I get the same message and I have all those dependencies already installed :(

[flauschzelle]

I (kind of) found a solution:

I cloned this git repo and copied all the contents of this folder into my .local/share/gnome-shell/extensions/[email protected] folder to replace the previous versions, and now it works as intended :)

Even though I had first installed the extension on this computer only a few weeks ago, it appears to have been a more outdated version than I thought.

Popping in to report my steps to get this working. This is on a fresh Pop!_OS 22 instance.

• sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0 gnome-system-monitor per @hexdecimal16
• git clone https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet.git; cd gnome-shell-system-monitor-applet per @e11bits . I'm on commit b359d88
• NEW Edit [email protected]/metadata.json to change "version": -1 to "version": 42
• make install, log out and back in
• Open Extensions app, turn "Manually Installed" plugin on.

[ShrirajHegde]

You can also disable extension version validation temporarily (instead of doing this for several extensions)

gsettings set org.gnome.shell "disable-extension-version-validation" true 

[jmcvetta]

Or even easier without any editing:

git clone https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet.git cd gnome-shell-system-monitor-applet ; make install

This worked for me on Ubuntu 22.04. Requires a logout/login before the extension is available.

The same with me

• make install, log out and back in

I'm on Ubuntu 22.04 and this worked for me.

Note that many of the set of steps provided do not set the metadata.json file. As a result, for me, the extension would work after the logout/login. However, after a reboot, it seems Ubuntu updated the extension to the one from the "store", and as a result made the extension deprecated again. I had to uninstall the extension, set the version to 42 as mentionned in the quoted steps, and make install again. Now the extension survives rebooting!

[quanhieu]

Uninstall old gnome-system-monitor and install next version here https://extensions.gnome.org/extension/3010/system-monitor-next/

[ejgutierrez74]

Is there any easy way to delete this extension ? It appears as Outdated, and ive installed the system-monitor-next...so no reason to maintein this outdated....im on ubuntu 22.04.1

[bmaupin]

Here are the full steps I used on Ubuntu 22.04; a few notes:

• Based on this, the only prerequisite package seems to be gir1.2-gtop-2.0
• ⚠ Adjust the last line as needed, otherwise it may disable your other extensions. Or just use gnome-shell-extension-manager to enable it manually

# Install prerequisites (https://packages.ubuntu.com/impish/gnome-shell-extension-system-monitor)
sudo apt install gir1.2-gtop-2.0 git

cd /tmp
git clone https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet.git
cd gnome-shell-system-monitor-applet

# The packaged extension always has a version; set one manually
sed -i 's/"version": -1/"version": 42/' [email protected]/metadata.json
make install

# Cleanup
cd ..
rm -rf gnome-shell-system-monitor-applet

# Reload Gnome Shell; this is required for Gnome Shell to see the new extension
killall -3 gnome-shell

# Enable the extension
gsettings set org.gnome.shell enabled-extensions "['[email protected]']"

[igorpupkinable]

This is the most popular system monitor extension. I hope it becomes compatible with GNOME 42 out-of-the-box some day.

[johnmee]

@igorpupkinable You want the bottom one in your list "system-monitor-next"... https://extensions.gnome.org/extension/3010/system-monitor-next/

[lotyi]

You can also disable extension version validation temporarily (instead of doing this for several extensions)

gsettings set org.gnome.shell "disable-extension-version-validation" true 

thanks. it works for me. Manjaro 22.0 with GNOME 42.5
