Unable to log in and flashing command line message after restarting frozen Ubuntu 16.04.1 using REISUB

I restarted a frozen Ubuntu 16.04.1 session using Alt + PrtSc + REISUB and now the graphical login manager does not show and I cannot log in. The following message briefly displayed and then disappears in an ongoing cycle.

/dev/sda1: Clearing orphaned inode 12976130 (uid=0, gid=0, mode0100600, size=334)

I managed to log in using Ctrl + Alt + F1, however after a few seconds, the screen flashes black, and continues displaying the message above in the same manner. I can press Ctrl + Alt + F1 and the login is still active.

I've tried restarting it a few times using the power button with no success.

How can this be resolved? I still have access to recovery mode.

Solution 1:

Try holding Alt+Ctrl+F2 It seems to do that randomly sometimes. It could be due to a late start of gdm, but I'm not certain as I don't know what each application does exactly. I do know that my graphical interface disappeared as well and went to that same screen, but the interface was still on tty2, so I just switched back over to it as simply as the above method.
