ps: the booting problem (black screen) also occurs when the system is somewhere on the road, not connected to any network. *two: /dev/sdb1 is an external usb disk which should not interfere. It could be half connected or some other problem. I'll do an fsck on it -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960605 Title: System freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1960605/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
