Ubuntu machine is not booting properly? [solved]

When you press the power button of your Ubuntu machine or Linux Mint machine if it does not boot properly, try this it will fix your issue.

Reason :
when you shut down your machine last time, it may not have shut down properly. So some Operating System data may have been corrupted.

Message of the black screen:

nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 6013d4 [ IBUS ]

nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 10ac08 [ IBUS ]


You are in emergency mode. After logging in, type “journalctl -xb” to view
system logs, “systemctl reboot” to reboot, “systemctl default” or “exit”
to boot into default mode.
Press Enter for maintenance
(or press Control-D to continue):

You can fix this issue following steps below.

  1. Press “Enter”.
  2. Now you are in command line as root user.
  3. Type
    fsck -AR -y
  4. Wait for few seconds untill process finished.
  5. Done! then type the “systemctl reboot” or “sudo reboot” to reboot the machine.

Now your machine will boot smoothly.

I have installed following applications to my machine.

  1. Kdenlive
  2. GIMP

I have a doubt above mentioned applications may be the reason for this data corrupting issue when shutting down the machine.
