I tried testing again with the newest Ubuntu liveCD, and at least in that environment it works correctly. And the wifi reconnects much more quickly too. It's looking more likely that this is some strange quirk of my system which has been upgraded a few times and may have some bad config hiding somewhere.
Is there an accepted way to reinstall Ubuntu on top of an existing installation, preserving at least the home directory? Otherwise I'll just flatten and reinstall and see if that fixes it. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1261753 Title: [Dell XPS 13 (L322X)] Laptop often suspends once immediately after resume Status in “linux” package in Ubuntu: Confirmed Bug description: It takes 10-15 seconds for the second suspend to trigger. I can tell I'm going to get a double-suspend when the network doesn't come up after resume. I have tried the nmcli nm sleep false trick.
