Can't shutdown/reboot/suspend system

:+1: Welcome to Manjaro! :+1:

    • Remove this:

      from GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub

    • Ensure all your files are saved and no applications are running before going to the next step.

    • Execute:

      sudo update-grub
      sudo reboot
      
  1. If REISUO doesn’t ring a bell, please read this:

    [HowTo] reboot / turn off your frozen computer: REISUB/REISUO

  2. After a REISUB, post the output of:

    journalctl --boot=-1 --priority=3 | tail --lines=50
    
  3. Why? Because the GTX 660 is supported by the 460.56 series driver.

  4. doesn’t provide memory information nor a lot of other things. For the future, use

    inxi --admin --verbosity=7 --filter --no-host --width
    

    instead.
