Scary Ubuntu incident

Charles Irons
Hello Ubuntu Technical Support

Ubuntu died on me today while it was doing nothing for me.

The sidebar with all my apps , active and inactive, was still shown but no "Activities" icon at top left.

None of the apps could do anything and the "Show Apps" grid at bottom left flashed icons on the screen that went blank.

I tried to shut down but the power light on my PC box kept flashing. Pressing it reverted to the same display of the sidebar with apps.

Finally I disconnected the mains power and then restarted. That worked OK so I opened system log files and copied parts to gedit.

I have saved syslog and dpkg.log but they are big and I don't know what may be relevant. 

Please check the strange time stamp sequence in the auth.log below.

Is there anything I need to do to secure my data and system software?

Thanks for your attention. Chas (old retired user)

Sounds like your power button is set to put the computer to sleep, not
to turn off.

OK, 2 hints here.

[1] For any Linux computeh with a graphical  desktop, if the desktop
crashes really badly and you can't use it, you can reboot cleanly by
pressing

Ctrl+Alt+F1

(or F2 through F6) until you see a text screen, and then pressing

Ctrl+Alt+Del

This is *much* safer than pulling the plug.

[2] If even that doesn't work, almost any kind of computer can be
forcibly turned off by pressing *and holding* the power button for
about 10 seconds.

This is no better than pulling the plug, but it's easier.

If the infamous three-finger-salut does not work,

Try holding down ALT + SYSRC, and press sequentially, one key after another:
R
E
I
S
U
B

((This should perform a restart, but if you rather would do a shutdown, type: )),

R
E
I
S
U
O
