Startup problem in 16.04? [duplicate]

After upgrading from 14.04 to 16.04, in startup it shows

/dev/sda1: clean, 291272/4292608 files, 480345/18174432 blocks

which makes Ubuntu take some time to load.

Same problem here. I thought this problem was due to the changes that I made in the secure boot settings (UEFI) in the upgrade process of my dual boot laptop (ubuntu and windows). After browsing some forums and comments section, I finally found the solution (for my laptop at least, I dont know if this works for everybody)

Open terminal at log-in screen (ctrl+alt+F2) after logging-in, run sudo apt-get purge nvidia*

/dev/sda1: clean, 291272/4292608 files, 480345/18174432 is output from a fsck check.

In the /etc/fstab file you probably have a line that looks like this:

/dev/sda1 / ext4 errors=remount-ro 0 1

According to the fstab information the 1 on the end of the line is the pass number. The definition to that is:

Controls the order in which fsck checks the device/partition for errors at boot time. The root device should be 1. Other partitions should be 2, or 0 to disable checking.

Which will make the system check the / root partition with fsck during boot time for errors and correct them if any are found. This can cause a slow down during the system boot for the check. This should not run every boot up as I believe that there is a flag to let it know if it needs to run or not.

Some observations I have found from upgrading and clean installing Ubuntu 16.04:

Clean install of Ubuntu 16.04 has defaulted to LVM partitioning scheme. This has created an ext2 root partition that gets checked with the fsck command on every single boot.

Upgrade install over an old Ubuntu 14.04 installation keeping the drive at ext4 has not caused the host to run fsck at every boot.

It appears to me that having the ext2 format on the root partition causes fsck to run at every boot.

Hope this helps!
