I have the following output and my ubuntu boots very slowly. it takes like 2-3 minutes to boot up where was windows only takes like 15 seconds. Here the output of journalctl: http://paste.ubuntu.com/24706296/

It would be nice if someone could help me as i'd really like to boot fast into ubuntu.

I have everything on SSD (/) but only /var and /home on hdd.

Partial answer... work in progress...

Step 1:

You may have some disk corruption on your SSD.

Lets first check your file system for errors.

To check the file system on your Ubuntu partition...

  • boot to the GRUB menu
  • choose Advanced Options
  • choose Recovery mode
  • choose Root access
  • at the # prompt, type sudo fsck -f /
  • repeat the fsck command if there were errors
  • type reboot


Now we begin to fix your /swapfile problem.

Edit your /etc/fstab...

gksudo gedit /etc/fstab

Change this line:

/swapfile   none   swap    sw              0       0

To this:

#/swapfile   none   swap    sw              0       0

Save the file and quit gedit.

Reboot and note if there's a boot time improvement.

More pending...

If boot times improved... delete /swapfile...

Create a swap partition or swapfile on /dev/sdb...

Edit /etc/fstab...

Delete /dev/sda7 swap partition...

Step #3:

There seems to be problems with 17.04 and encrypted swapfiles... and there are some workarounds...

Edit your /etc/crypttab like so:

gksudo gedit /etc/crypttab

Change this line:

cryptswap1 UUID=xxxx-xxxx-xxxx-xxxx /dev/urandom swap,offset=1024,cipher=aes-xts-plain64

To this:

cryptswap1 /swapfile /dev/urandom swap,offset=1024,cipher=aes-xts-plain64

Also make sure that your /etc/fstab contains this:

/swapfile               none  swap  sw  0  0
/dev/mapper/cryptswap1  none  swap  sw  0  0


Ubuntu Desktop 17.04 64bit slow boot



  • I've completeley reinstalled before I read your answer. It didn't help my bootup still takes long. I've set up a completely new swapfile, now the swap works. After reboot I have 4GBs of swap. Anyway, I did what u said, scan my filesystem for errors, but i didnt get anything. What I got was some error about cryptswap. Because I set my home folder to be encrypted. Heres a picture of everything: goo.gl/photos/p6MwdPBJjNEXt9Cq6 – Uwe Pfeifer May 30 '17 at 20:52
  • ive tried commenting /swapfile in /etc/fstab but it didnt help. it still loads that long. one thing. when the system boots up, for a really short time it displays some text but it goes away too fast i cant read it. is it possible that my system scans something every time on boot up? – Uwe Pfeifer May 30 '17 at 23:41
  • I only wanted to comment out your original /swapfile because it was causing problems. It was sized incorrectly, and probably didn't have mkswap performed on it, and your journal log showed the problem. Since you've reinstalled, the /swapfile is probably fine, so commenting it out now won't make any boot difference, unless you have the same problem as before. You will still want to relocate /swapfile to the SSD. The message that you briefly see is fsck telling you that the file system is clean. – heynnema May 31 '17 at 2:49
  • this helped. thank you very much my system boots within 5 seconds now! :) – Uwe Pfeifer Jun 1 '17 at 15:37
