[Bug 1415039] Re: laptop unresponsive after suspend
The message in /var/log/pm-suspend.log quoted in the report "Failed to connect to non-global ctrl_ifname: (null) error: No such file or directory" comes from the wpa_supplicant sleep hook. This hook shouldn't be run when NetworkManager is operating, since NM handles sleep and resume DBus notifications itself. More often than not, the result of the race between the two is a half-working network that appears from the GUI to be working but actually isn't and has to be fixed by disabling and re- enabling Networking. At any rate it isn't connected with the original problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1415039 Title: laptop unresponsive after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1415039/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can you try something for me? I'm wondering whether you're getting the same thing I reported here that may be a part of another, earlier bug (https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1375271/comments/8). When you resume from suspend and find the system non-responsive, press ctrl-alt-f1. If you get a text login screen, don't do anything on it, but press ctrl-alt F7. This should bring you back to the visual session. Do you then get an unlock screen or a working desktop? If so, it's probably the same issue I'm having (waiting to see if it should be a new bug or a continuation of that old one). If not, let me know anyway just so I can cross it off the list. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1415039 Title: laptop unresponsive after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1415039/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
