enter image description here

dev/sda1: clean, 552599/6111232 files, 7119295/24414464 blocks

After I turn on my laptop this message appears. The system never boots, the message just stays there.

    This is a normal startup message. It lets you know that there are no filesystem errors. – heynnema Feb 11 '17 at 20:49

    this message does not disappear how can try this solution – El-Dow Feb 12 '17 at 16:24
  • This message is OK. – Pilot6 Feb 12 '17 at 17:09
  • @Pilot6 OK? but how can use OS – El-Dow Feb 12 '17 at 17:28

    Oh, I see askubuntu.com/questions/162075/… – Pilot6 Feb 12 '17 at 17:30

I have had this problem occur a few times, and every time it was ODDLY Nvidia's fault - yes COUNTER-INTUITIVELY

If in Ubuntu after a long painful reboot run:

sudo apt-get purge nvidia*

or if locked try Ubuntu's awesome way of troubleshooting and try: Ctrl+Alt+F1 through F7 to get to "TTY1-7" and run the same thing. Reboot for good measure, and re-install Nvidia's Proprietary Drivers.

I hope I helped, Mark

    Good lord, after trying dozens of other things, this is what eventually worked. – wordsforthewise Nov 25 '17 at 21:18

    Please note, that the /dev/sda1:clean message comes from fsck being run at boot time (see answer here). The fact that OP's system wouldn't boot has no relation to the message. Booting issue was likely due to improper graphics driver being used, which is why this answer worked for some people. – Sergiy Kolodyazhnyy Dec 17 '17 at 7:48

    But what if we need NVIDIA, e.g. if we're using their GPU? – ComputerScientist Feb 18 '18 at 20:04

    @mikewhatever 🙄 how are you so sure?! This happened to me twice already and it's just after a kernel update. The nvidia module goes missing and the system never finishes booting. Removing the driver (to clean anything that reamined) and then installing it again (thus creating a module for the new kernel) solves the issue. I'd be glad if you can prove it has nothing to do with that and explain us why. This is not "nonsense". – Enrico Jul 2 '18 at 22:57
  • I'd be glad to prove it, if you can arrange access to your PC for evaluation. Without that, asking for something like that poses an impossible task. The nvidia module should get auto-rebuilt by dkms after a kernel update. It's been working for me for many years on multiple PCs with different Nvidia cards. I've never ever had to remove the driver and reinstall. – mikewhatever Jul 6 '18 at 17:57

ctrl+alt+f2 or f3

  • login with your account
  • type sudo apt-get update (enter password when prompted)
  • type sudo apt-get install xserver-xorg-video-intel
  • reboot

  • or type journalctl and check what is going on there – swietyy Oct 16 '18 at 16:56

I experienced the same problem; though Mark's (top answer) solution didn't immediately work (since ctrl+alt+F2 etc. brings up a flickering TTYL which is nearly impossible to use), his suggested cause was correct, as it was a problem with the nvidia driver.

Also for beginners like me, here's the fool-proof step-by-step solution:

  1. Boot into safe mode (recovery mode). Enter this mode by holding the left shift key when the computer starts.

  2. in terminal, type:

    sudo apt-get purge nvidia*

    sudo ubuntu-drivers autoinstall #Make sure you have internet connection

Other solutions suggested elsewhere didn't work (e.g. installing boot-repair or sudo apt-get update)

(This worked on my dual booted computer (Windows 10 and Ubuntu 18.04)

my error message was /dev/nvme0n1p5: clean, nnn/nnn files, nnn/nnn blocks

    I tried many things (including changing my display manager). sudo ubuntu-drivers autoinstall is what finally worked for me, thank you! – cyrusbehr Dec 31 '19 at 1:15
  • It worked for me in normal mode also, not necessarily in safe mode. – RecklessSergio May 26 at 3:11
  • It worked perfectly for me. Thanks – Nuno Rolo Jul 16 at 13:27

Step #1

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

If for some reason you can't do the above...

  • boot to a Ubuntu Live DVD/USB
  • start gparted and determine which /dev/sdaX is your Ubuntu partition
  • quit gparted
  • open a terminal window
  • type sudo fsck -f /dev/sdaX # replacing X with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot

Step #2

If step #1 doesn't fix your problem, then do this...

  • boot to the GRUB menu
  • choose Advanced Options
  • choose Recovery mode
  • choose Root access
  • at the # prompt, type:
    • sudo blkid
    • sudo cat /etc/fstab
  • edit your question to include the output from the two previous commands
  • type reboot

Step #3

pending fix here...

Step #4

If you dual-boot with Windows, then do this in Windows...

  • open the Power control panel
  • click on change what the power buttons do
  • click on change options that are unavailable
  • uncheck fast start
  • close the Power control panel
  • open an administrative command prompt window
  • type powercfg /h off (turns off hibernation)
  • type chkdsk /f c:
  • approve that chkdsk runs at next boot time
  • reboot Windows

  • Run these steps and tell me the result, and I'll finish the answer with the final fix. – heynnema Feb 13 '17 at 21:32
  • I have the same problem, it shows me the same /dev/sda1: clean..... message when I run the sudo fsck command. I type fsck and then reboot, however the problem still persists. I am not dual booting, I intend to have one OS that is Lubuntu on my 8 yr old netbook. Can you suggest what to do next – Transistor Overlord Dec 1 '17 at 16:03
  • @TransistorOverlord please start a new question. Provide as much detail as possible. Describe exactly what you've tried to fix the problem. – heynnema Dec 1 '17 at 16:29

I am not sure if this will work for everyone but I managed to fix this by removing every occurrence of nomodeset from /etc/default/grub file and then by executing sudo update-grub.

This was because nomodeset disables the use of any graphic driver. I disabled my nouveau drivers before installing nvidia ones.

Though this might not be the case with everyone.

  • Thanks, yes that make sense too. I have alienware 13 R-3, To install ubuntu I added nomodeset to enable ubuntu os to load. Once I installed nvidia driver, I was getting the above error. So on grub I pressed e for edit and removed the nomodeset and ctrl+x to rebboot. After that I got desktop all fine. – Mian Asbat Ahmad Mar 11 '19 at 13:31

I had the same problem. Neither of the answers worked for me. I have an old laptop with an Atom processor which hasn't Nvidia graphics. Thus, I've adopted an alternative solution with nomodeset mode as following:

In installation scene, press F6, use arrow keys to go down to nomodeset, and press Enter. An x will appear to its left. Then press Esc, and press Enter to "Try Ubuntu without installing" or "Install it".

I had this problem with fresh install of 18.04.3 desktop on proxmox 6.1 Had to change to vmware compatible graphics for the VM before it would work..

| improve this answer | |

I reinstalled Nvidia drivers and the PC started working:

ctrl+alt+f2 or f3

  • login with your account
  • sudo add-apt-repository ppa:graphics-drivers/ppa
  • sudo apt update
  • sudo apt install nvidia-settings
  • reboot

(thanks to @Shahad and his solution at https://askubuntu.com/a/1218483/750140)
