When my laptop is at work (running OpenSUSE Tumbleweed), and when the network cable -> USB adapter is plugged in, eventually in a day the computer sort-of-freezes. I can still operate everything normally, but as soon as I attempt any sudo command, the process attempting it freezes; this includes sudo reboot. On the other hand, doing an su -s still seems to work. It's purely the sudo that is frozen, and it seems to be related to being plugged in to the network via the USB adapter.

As a side note, this does NOT happen when I use KDE as my window manager; however, I usually use exwm (emacs). I can't even think of a possible explanation. Any ideas?

  • What the brand and model of your notebook? does it have an ethernet port? – Rui F Ribeiro May 9 '18 at 23:34
  • Access to /etc/sudo.conf sounds like one of the suspects. – ajeh May 10 '18 at 0:10
  • @RuiFRibeiro No ethernet port; it's a Dell XPS 13 – Webdev Tory May 10 '18 at 16:32
  • defining your hostname in /etc/hosts is it possible, and does it solve the problem? – Rui F Ribeiro May 10 '18 at 16:46
  • In this case, I would be more inclined that you could be using a dodgy ethernet adapter. Please details the brand and/or the output of lsbusb command in the question. However, the XPS 13 has known wifi problems due to bad design of the board. – Rui F Ribeiro May 10 '18 at 16:48
