Public bug reported:
I had left my computer with my Ethernet connection in and I don't have the
correct wireless drivers so I cannot use that, and my computer went to sleep
with my Ethernet wired connection still in, and when I tried to wake my
computer as normal by pressing the power button it made noises and it stopped
glowing as it does when the computer is sleeping, but the screen was still
black. I then after waiting for about 30 seconds, pressed it again and then
finally the screen came on and it asked me if I wanted to shutdown, restart or
suspend, and as I had clicked the power button again to just wake it up
properly (it has never happened before that pressing the power button once does
not work) I closed that dialog. I then typed my password in in the log-in
screen and it logged me in and I was still logged into some online services and
I tried to log out of them and it told me that there was no internet connection.
I then had a look at my connection status and it said something like
"Networking Disabled", and the "Enable Networking" option did not have a tick
next to it, so I ticked it, but this made no difference other than adding a
tick next to the option in the pull-down menu from the bar at the top right.
I went into the "Network" options in System Settings and it said that there was
a connection, but that it was "Unmanaged". I was spooked by all this so I
restarted my machine and all works fine now. But I thought that I should file a
report anyway as this is not normal and not meant to happen. And if it happened
permanently then I would have no internet access and would have to start
in-depth debugging in the system which would probably take lots of time and
effort. It was also a little worrying that it would not wake up immediately.
