When installing CLS on my laptop, I’ve noticed that as soon as I install laptop-mode-tools, it breaks the configuration of networkmanager. The network interface is an USB ethernet dongle. Before I install laptop-mode-tools, NetworkManager start the interface without issue (fixed IP), but when I install laptop-mode-tools, the interface doesn’t come up properly. A ping from another system shows me that sometimes the interface comes up briefly (I receive a resulting ping), but then it goes down again.
Forgot to add, after logging in, I can nmcli c up eth0 and it’s working (with using laptop-mode-tools).
