    Lubuntu & modem-manager : crash on reboot

    Hello,

    I have Lubuntu 16.04.5 LTS on an ARM board (https://www.friendlyarm.com/index.ph...product_id=227). All is going well, except one big problem with 4G...

    By default, I can create a "Mobile broadband" connection but I can't connect on it. So i install "modem-manager" with "sudo snap install modem-manager" command.
    I now can connect on my 4G and it works.

    But the problem is that it crashes on every reboot (black screen). I did many Lubuntu fresh installs and some problem everytime, when i install modem-manager with "sudo snap install modem-manager", I could not reboot anymore after that (black screen).

    Thank you very much in advance for answer,
    Best regards!

    I found the problem !!!
    Add "blacklist qmi_wwan" to /etc/modprobe.d/blacklist-modem.conf file
    Reboot
    It works!
