On every bootup it's the same:  /dev/sda1: clean, 908443/38690816 files, 44176803/154733312 blocks   Is it some kind of option Ubuntu uses to ensure filesystem consistency or is there something wrong with my HDD? fsck takes up to 30s while booting and so about triples the time needed otherwise.

I've been running Alpha releases of Ubuntu for some time now. I keep running into issues - how can I get these resolved? What should I do when I encounter these problems? And where can I find other Ubuntu+1 users to ask questions?

I've started getting random blue screens from my (admittedly aged PC). Unfortunately it reboots straight away so I don't get chance to read the error. It's been happening when browsing Stack Overflow in Google Chrome and Firefox so I'm assuming that it's something fairly fundamental.  Most of the time it puts up the "Report the error to Microsoft" dialog and I've checked the data files it wants to send but can't find the information there. I'll freely admit I could be looking in the wrong place.  I'm running Windows XP SP3 and I'm fully up to date with the updates.  The CPU is an Athlon XP 2600+, I've got 2 GB of RAM installed, an nVidia Quadro4 980 XGL driving two DELL 2001FP flat panels at 1600 x 1200 pixels (32 bits/pixel).  I've checked the CPU fan (which has been recently replaced) and that seems to be turning freely. The insides are a little dusty, but not excessively so.  So I need to either stop it rebooting or find out where the error code is stored so I can read it after the reboot.  UPDATE 22/09/2009  OK - just had the BSOD and it's in win32k.sys. I'm doing some research to see if I can find anything that might help. If I get stuck I'll post a new question. Thanks for all the suggestions.

I upgraded to Ubuntu 20.04 today, choosing LightDM over gdm3 during the upgrade. During the upgrade I was asked if I wanted to keep or replace /etc/sane.d/dll.conf file. I decided for keeping it. Now, without actively rebooting, the &quot;Oh no! Something went wrong&quot; screen appeared. As I am still inexperienced with this kind of troubleshooting, I feel it wouldn't be safe to just try out answers from other threads that don't have exactly the same 'history'. Solutions I read included Ctrl+Alt+F4 and trying to login and get more information from the command line (). Is that safe to do? Ideally, I'd like to save my data that is stored on an encrypted harddrive before trying to fix errors. I'd like to avoid reinstalling the OS. From reading other threads, I know this post may be criticised as not being precise enough or haven't tried enough, but really I cannot get more information from that white screen myself and don't want to risk ruining everything just to provide more information... Thank you for your help!! :) Edit: I have no idea if the problem is related to lvm2-activation-generator, as in  This and other solutions include booting from a live usb. Can I do this 'safely' by simply switching the laptop off at this stage? Do I have to do sth before?

I've been trying to install ubuntu 11.04 on Asus k50IJ notebook. All via Wubi went without problem. After a reboot, everything starts but during veryfying the installation, this error appears:     "No root system file defined"   I tried to run chkdsk because I thought there might be some HDD problems, yet nothing has been found.

What happened  I was working on my laptop while it upgraded from 15.10 to 16.04 (which I admit was a mistake) when suddenly the Unity overlay disappeared and the only thing on screen was the Firefox browser window. I switched to a new terminal, logged in and tried to run sudo service lightdm restart but instead of restarting correctly, the screen started turning on and off repeatedly, which freaked me out, so I physically turned off the PC.  Long story short: I forced a shutdown halfway through the Ubuntu upgrade.  Ever since, any attempts of logging in normally have been met with a solid black screen and the idle whirring of the CPU fan.  What I have tried  I have tried the recovery mode boot up, but no luck (The log does greet "Welcome to Ubuntu 16.04 LTS!"). I tried out each option that seemed useful:   dpkg goes through the packages as advertised, but strangely enough it always locks up on some Braille package until I do Ctrl+C, at which moment it spouts some error messages and then I think throws me into the normal boot. failsafeX results in a similar situation to the normal boot: a black void. fsck says the single partition I have is a-ok. grub seems to get a bunch of stuff. Don't know if it searches locally or fetches from the internet. network didn't work I think.   I tried following  but couldn't do the sudo part because the filesystem was mounted as readonly. So I ran fsck which mounts as RW and tried again.   This time, after running apt-get autoremove it went through many packages (Setting up foobar (X.Y.ZubuntuN) ...), sometimes installing packages, which I assume is the usual behavior. One thing to note though is it kept getting stuck several times, so I had to Ctrl+C it out of processing the current package. It finally ended on "Processing was halted because there were too many errors.".  While  seems to mention some of the graphics problems I've been experiencing... I have Intel HD Graphics, not Nvidia. I'll keep looking into it.

How can I find out the size of a block device, such as /dev/sda? Running ls -l gives no useful information.

Ubuntu doesn't boot up and it goes into initramfs. I am writing from a live CD trial session. what should I do?  I understand that the boot flow is broken and that when the files from root are going to be loaded into the ram, it does not find the files in the root directory. Please correct me if I'm wrong.  The following is the output from ashell as I input the "exit" command:  (initramfs) exit /dev/mapper/ubuntu--vg-root contains a file system with errors, check forced. Inodes that were part of a corrupted orphan linked list found.  /dev/mapper/ubuntu-vg-root: UNEXPECTED INCONSISTENCY; Run fsck MANUALLY.     (i.e., without -a or -p options)  fsck exited with status code 4. The root file system on /dev/mapper/ubuntu--vg-root requires manual fsck

This problem happens sometimes when ubuntu starts up. You can't really boot to the interface sometimes.  Splash Screen with the 5 dots and a message saying:     waiting for network configuration   followed by:     waiting an additional 60 seconds for network configuration

After upgrade to 15.04 my ubuntu loads really slowly, slower than Windows 8 on the same machine, which insults me.  I turned off splash screen, and when I boot the system I get this:  A start job is running for dev-hdb2.device   and It stays that way for 1:30 minute, with a time counter next to it set exactly to 1:30.   Also when I reboot I get this message:  A stop job is running for Session c2 of user MrMino   same here - it stays that way for 1:30  Output of dmesg:   Unfortunately bootchart isn't working for some reason not known to me now, so I can't post logs from it.  How to make this go away? I'm running ubuntu on Dell Inspiron 3537.

The process is not stuck because the terminal shows "progress", it keeps trying to remove files that it can't find, the messages read something like: /..../file x: Warning: Source ID XXXXXX was not found when attempting to remove it  The reason I am reinstalling is because my installation was messed up when I installed ubuntu-touch and the system wouldn't reboot.   I was able to fire up a live USB through grub and start the installation process, I figured it would be possible to simply reinstall but it seems to be taking forever. Is this normal behavior? Should I stop it and simply go with a fresh install instead?  Thanks!

Sorry for repeat the same thread but nobody answer me and I need a fix as soon as posible because I can't stay updating PCs going first to 15.10 and later to the LTS. Please help me! Thanks in advance!  This is the original message.  I have a Toshiba NB300 with 1 GB RAM with Intel® Atom™ processor N450 and I recently installed Lubuntu 16.04 LTS i386 and I have this message on the screen instead of the login box  /dev/sda6: clean, 124768/2379216 files, 881581/9509376 blocks   How can I fix it?  Thanks in advance.

Cross post from   I have a laptop I'm running as a file server, which is running Ubuntu 10.04 Desktop. Now that summer heat is here, and because I love the environment, I'm look for all sorts of ways to reduce the laptop's power/memory/heat footprint.  One part I never touch any more is the GUI as the lids always closed.  I thought perhaps simply removing GDM from all run-levels my achieve this, so I did so using sysv-rc-conf. However this didn't make any difference and upon reboot the lovely Ubuntu boot screen and graphical login prompt appeared.  Please help!  Additionally, perhaps this is a silly question, I want to make sure that the monitor is off at all times the lid is closed, which it is already set to do when the GUI is running, can/do I need to configure this separately for non-GUI environments? (Seems to be doing this fine)  Thanks :D  EDIT: Ok maybe I'm using sysv-rc-conf wrong and it needed 2 reboots to apply the settings or something? As rebooting it a second time since removing GDM from all run levels I got a command prompt.  However I didn't watch it reboot and was a little confused by this, so I rebooted what I believe to be a 3rd time, and now it's booted to a black screen with a solitary white underline in the top-left, no other text. No amount of keyboard mashing in order to change run levels is having any effect, however I am able to access it via SSH and the SMB shares, so I suppose it's doing almost what I want. The lack of a CLI on the screen itself is still concerning however.

My PC was working yesterday without any problem. I shut it down and tried to open this morning. It prints out these messages on the black screen:  systemd-udevd[713]: failed to execute '/bin/systemctl' '/bin/systemctl start --no-block nvidia-persistenced.service': No such file or directory  systemd-udevd[852]: failed to execute '/bin/systemctl' '/bin/systemctl stop--no-block nvidia-persistenced': No such file or directory   It then continued with the login screen. I entered my password and pressed enter. It waited for a while and the login screen reappeared again.  How can I fix the problem?

This morning I went to turn on a family member's laptop to find the SMART message displaying that the laptop's hard disk is close to failure and needs replacing.   The laptop is around 2 years old now and I have now backed everything up just in case of this 'imminent' failure.   I ran the HDTune programme to test the amount of damaged blocks there are in the hard disk.  This resulted in 24/2500 blocks (1%)  To me, (someone who doesn't know a great deal about computer hardware) this doesn't seem like a very large amount and I am not entirely sure where to go from here.   Shall I just suggest to immediately buy a new hard drive for the laptop as this one will just keep on deteriorating?  Or, as everything is now backed up, keep on using the laptop until the inevitable happens which could be; days, weeks or months, as this laptop isn't really used for anything majorly important?  Thanks in advance,  JD
