    Can't power off Ubuntu 16.04.2

    I have issues whenever I attempt to shut down my computer. Whenever I shut it down (using the GUI), the computer takes me off the main screen to the Ubuntu splash screen with the dots that illuminate one by one. This screen will not go away and the only way to shut down the computer is to hold the power button on the laptop. I do not wish to continue doing this because I am afraid of what it will do to my laptop. I have also tried shutting it down using different commands from the terminal, but I run into the same problem. Does anyone know how to fix this? Should I be worried that my laptop may be damaged if I hold the power button down at the splash screen to turn it off? Any help would be appreciated.

    Yes. Forced power down can corrupt your filesystem.
    Until you receive further advice on how to figure out why you can't shutdown, use this controlled shutdown procedure:-

    ...

    Press and hold down <Alt> key .. then slowly press in sequence (one key at a time) while holding down <Alt>:-

    <Print Scrn> followed by ..
    R
    E
    I
    S
    U
    B

    Here is one thread which might help.

    OK do I attempt the suggestion you made <Alt> etc. at the Ubuntu Splash screen?

    I tried the link thread you referred to. It did not work for me though

    OK. The link worked but it did not solve the problem I have.

    The key sequence will be tough to do before the splash screen comes up. It appears very quickly as soon as I shutdown the computer using the GUI.

    dragonfly,

    I tried the key sequence. I tried it once before the splash screen came up as I powered down the computer. I also tried it once at the splash screen itself. All it did was restart my computer. The splash screen went away and my computer just rebooted, but didnt shut down. Any ideas of what to do next?

    I use from time to time the Alt + PrntScrn,R,E,I,S,U,B key sequence when my desktop is frozen.
    I do not use it after starting the menu option Power Off.
    Here is a thread explaining it more fully.
    https://www.reddit.com/r/Ubuntu/comm...ps_responding/

    You still have the problem of troubleshooting why you can't power off cleanly. Refer to the last thread which had ideas.
    And also look to the right of the page to explore a list of several other threads with same theme.

    When you next boot up can you try selecting Recovery mode from your GRUB menu?

    Having read this linked thread can you give more information on what laptop you are using?

    OK I have a Toshiba Satellite A-215. The thread mentions a band-aid to for shutdown but no description. Do you have any band-aids solutions for this?

    The Alt + Prt Screen R E I S U B is to reboot. To shut down instead, do Alt + Prt Screen R E I S U O
