Further information, it turns out that pm-suspend is no longer used, and systemd-sleep is the new system. The scripts section of pm-suspend is still there, but it is broken as per https://launchpad.net/ubuntu/+source/pm-utils/+bug/1455097 (why does everything I look into seem to be broken????).
To fix the problem, I created the script (make it executable) /lib/systemd/system-sleep/broadcom_wl_suspend with the contents [code] #! /bin/sh #mp035: unload buggy broadcom sta driver during suspend. case $1 in pre) modprobe -r wl ;; post) modprobe wl ;; esac [/code] This has fixed the problem. I'm not sure where to push this from here, either the 1) the broadcom package should add ths script, or 2) or the broadcom sta driver needs fixing. Perhaps (1) immediately while we are waiting for broadcom to fix (2)? -- 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/1495043 Title: Suspend/Resume Regression 3.19.0-28-generic Dell xps15 Status in linux package in Ubuntu: Triaged Bug description: Suspend resume was working on 3.19.0-26 but 3.19.0-28 appears to suspend, but no longer resumes.

What happens: The keyboard backlight and the power button light come on, but the screen remains blank. Using Ctr-Alt-F1 does nothing (can't get to a virtual console, indicating that it's not just X that has stopped) What I expect to happen: On opening of the laptop lid, I expect the lockscreen to show.
