EDIT:

It seems like solving this problem is like rocket science, its unfixed. Instead of wasting time debugging it, i finally re-install the ubuntu.

Solution 1

Try this. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo apt-get install --reinstall ubuntu-desktop

Solution 2

Follow below instructions:

1. sudo dpkg --configure -a
2. sudo apt-get install --reinstall ubuntu-desktop
3. restart your computer and go to desktop

Solution 3

when I encounter this on my machine I simply delete the /etc/X11/xorg.conf and restart the system. BUT - I always make backups! :)

Solution 4

What display manager did you have before? Go to protected mode as root with Ctrl + Alt + F1 Then try reinstalling the following packages:

apt-get install --reinstall xorg-xserver*
apt-get install --reinstall gdm
apt-get install --reinstall unity

In case you have a different display manager than gdm, type kdm or lightdm.

I once had that too - regarding nvidia-drivers ...

Solution 5

There was posted in Ubuntu-forum this here to solve the problem after

"Stopping userspace bootsplash" appears like in your boot-log:

With the proprietary drivers installed they did the following:

Ctrl + Alt + F1 (To open up a terminal) and after login:

sudo apt-get clean

sudo apt-get autoclean

sudo apt-get autoremove

sudo dpkg-reconfigure -phigh -a

reboot

Entered Grub recovery mode and selected "repair damaged packages"

reboot

Hold Shift to get to grub menu hit E to enter temporary changes into grub place 'vmalloc=192MB' next to quiet splash

F10

And problem now solved ?!

They then made the change permanent by editing the /etc/default/grub to include:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=192MB"

Maybe this solves your problem ? Let me know !

Try sudo startx what happens?

[Admin]

@Mitch: FAILS (no luck)

[soulsource]

Please post the contents of /var/log/Xorg.0.log to pastebin and link it. Without having any clue what could be wrong, you could try to move /etc/X11/xorg.conf and all files in /etc/X11/xorg.conf.d to a backup directory.

[Admin]

@soulsource: here plz find: paste.ubuntu.com/5881280

This is strange. It seems that the Intel graphics card driver does not find, or more probable, cannot use your graphics chip. What happened before your system stopped working? Is the hardware detection at least correct, meaning, is it an Intel graphics chip?

[Admin]

@soulsource: yes its working perfect when i 1st install and when i use LiveCD, but suddently now it does not work at all when i run from Disk. but when i use liveCD it works

[soulsource]

Since it seemed to be an issue with the intel driver, you could try to purge and reinstall it: sudo apt-get purge xserver-xorg-video-intel and sudo apt-get install xserver-xorg-video-intel, but I'm not too optimistic that this will help. Be careful when purging - I have no clue which other packages might depend on it... Another possible cause would be that you might have updated this package to xserver-xorg-video-intel-lts-quantal - in that case, you can try to remove xserver-xorg-video-intel-lts-quantal and install xserver-xorg-video-intel again.

[Admin]

@soulsource: just did it, but no luck still same, it boots to terminal without having any GUI at all.

[soulsource]

Ok,I have to confess, I have no clue what else could be the cause.

[Tianyu Liu]

Dont had any xorg.conf file even.

[Admin]

I have SSH access and CTRL+ALT+F1 terminal access only. There i have done also reinstall of ubuntu-desktop. After reboot still same.

[dschinn1001]

@YumYumYum - what display manager did you have before ?! go to protected mode as root then do try reinstall of different packages:

[Rodislav Moldovan]

hm.. you can try this :: sudo dpkg-reconfigure xserver-xorg but please be carefull, or try to see what youtube is showing on this topic.

[Admin]

FAILED - not working, still boots in the terminal screen, no desktop.

[dschinn1001]

@YumYumYum - you still did not tell, what window-manager you used ? It was unity ? What happens if you install gnome ? or KDE ?

[Admin]

Unity, default Ubuntu desktop.

[dschinn1001]

@YumYumYum - have you seen my 2nd answer ?! getting closer to solution ?

[dschinn1001]

@YumYumYum - you have settled the rest after reboot ?

[dschinn1001]

no - it is the grub repair modus - when pressing shift - not reaching this ? "recovery mode" ? - well, but thats already much ! now supergrub-CD would help ?!

[Admin]

Step 1: clean/autoclean/all done Step 2: changed the grub settings Step 3: update-grub / update-grub2 is applied. but still i have same problem booting in to terminal no GUI.

[dschinn1001]

have you read that after 2nd reboot ? read the lines slowly. press 'shift' to get to grub menu and hit 'e' (for edit) - read above.

[Admin]

YES - those are done, basically if you do it after login permanently its same. /etc/default/grub is same by hitting shift/e.

[dschinn1001]

Don't know how to proceed - could be something quite different and banal: a) you ask this guy here - he solved it: ubuntuforums.org/showthread.php?t=2147113 b) it is banal and only a wrong spell-checking about directories ? like here: askubuntu.com/questions/65852/cannot-login-to-my-user-accoun‌​t/… - more I have not found out ... soon bedtime here.

[Admin]

i removed the ~/.Xauthority file but still not fixed (From your second link).

Tried did not solved, wired

I just built a new computer, took the hard disk from my laptop, put it in my new desktop, but couldn't get X working with the new hardware. Deleted the xorg.conf and immediately everything worked perfectly! Thanks!

@YumYumYum how do I go back to UI after CTRL+ALT+F1 ?

[Radu Craciun]

worked for me just by making clean, autoclean, autoremove and reboot. Thanks!

[hal]

I've opened terminal with Alt+F2 when my ubuntu stops during the boot. Hope this helps someone.

[mredig]

this worked for me between running the command on xorg and gdm3 (ubuntu 18)

[oscar1919]

works also with lubuntu-desktop :)

[Philippe Paré]

works also with gdm3 (gnome)

[Hristo Atanasov]

I hit esc key during boot to enter into recovery mode and login via terminal. Some useful info here wikihow.tech/Recover-Ubuntu
