Although GNOME Shell integration extension is running, native host connector is not detected

This is a bit of a nuisance, after a fresh install of Ubuntu Gnome, I was not able to install extensions from extensions.gnome.org.

Firefox asked me if I’d like to install the extension but after a Firefox restart I still wasn’t able to install any plugins.

To be precise; this message was shown:

Although GNOME Shell integration extension is running, native host connector is not detected. Refer documentation for instructions about installing connector.

The solution was to install the chrome-gnome-shell package;

sudo apt-get install chrome-gnome-shell

This fixes the message from both chrome and firefox.

Fedora Gnome-shell abnormal high CPU usage in combination with Intel GM 4000 videocard

I’ve been using my trustworthy thinkpad for a couple of years now, but as soon as I installed Fedora on it, it became quite slow due to gnome-shell using a huge amount of CPU power.

My thinkpad isn’t the quickest out there, it’s a dual core machine from around 2006, but 50% CPU on two cores for just Gnome was a bit excessive.

I’ve been searching a lot, and didn’t found any solution, until I started fiddling with Gnome-tweak-tool and saw the “Background logo” entry.

If you haven’t yet; Install gnome-tweak-tool with the following command:

sudo yum install gnome-tweak-tool

The background logo is an PNG overlay on your desktop, and that overlay doesn’t work well with Intel GM cards.

Start gnome-tweak-tool, disable that extention and see your CPU usage drop to 2%, which is what it should be.
