Hello,

I found that my BB AI has a quite high idle load (around 15% on both cores, 225MB of RAM used. Measured with htop). Has anyone else experienced the same?

Maybe, there is a striped down debian image (dabian 9 or 10) that only contains the necessary applications?

Regards

Stephan

Depends what you call necessary. There is a Debian console-only image.

I just tested through some images. As far as I can tell, the lxqt-panel generates around 11% CPU load. The debian 10 alpha (without graphical desktop) needs way less resources on idle.

For my plans I want to have the option of a graphical desktop, so I have to live with that.

I found you can stop the lxqt-panel process to save on CPU load. It runs even if no display is attached. If you were running headless then I would stop the whole graphical desktop environment.

Thanks for your response.

For now I deactivate the the lxqt-panel via systemctl:

sudo systemctl isolate multi-user.target

And restart it with:

sudo systemctl start graphical.target

Maybe someone else finds this handy

You can take this further if willing. Since no display is needed you may edit the device tree file to disable GPU, BB2D, DSS, and HDMI.
