I have done some test with Kubuntu 9.10 x86_64 / 10.04 x86 / 10.04 x86_64 inside a VirtualBox environment.
The bug is 100% reproducible. Reading your last message, I have noticed that in Kubuntu there isn't a way to edit the "Auto Eth0" connection (as you do). It is shown by knetworkmanager and by plasma-widget-networkmanagement as available, but if you go to the "Manage Connection" panel only the custom connections are shown. The "Auto Eth0" is hidden. I have attached a screenshot. After I create my static connection, the "Auto eth0" remains alive and I can't de-select the "connect automatically" item. I suppose it takes priority over the other connections. If this is true (and I think so), the only way to use network-manager in Kubuntu is only through dhcp... This is definitely a Kubuntu/Kde bug, not a network-manager bug. I'm going to open a new bug. ** Attachment added: "auto-eth0-missing.png" http://launchpadlibrarian.net/49846802/auto-eth0-missing.png -- Static IP ethernet network setting is lost after reboot https://bugs.launchpad.net/bugs/303068 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
