Ubuntu – Ubuntu 14.04 hangs on “Restoring resolver state…”

14.04bootdriversgrub2nvidia

I have A VM with guest Ubuntu installed which I use for development. Everything was setup and working nicely until yesterday evening when I rebooted the VM (updates were installed during that session, if I recall correctly). The booting splash screen showed up and just hung there.

I looked into these questions and their solutions and high rated answers:

… but with no success.

If I press Right Shift when the VM fires up and choose to use Ubuntu with older version of kernel (latest shown 3.19.0.-51-generic, first older 3.19.0-49-generic), then I successfully get to the login screen but can't login with my credentials, it just keeps throwing me back to the login screen. TTY login works.

I used the recovery menu to drop to root shell and reinstall nvidia-current package, removed "quiet and splash" to see what's going on, cleared /tmp directory as suggested in one answer, updated grub, but with no success. Is it possible to rollback the updates somehow? Here's where booting hangs:

The VM is running on an SSD disk partition, 60GB of space, with ~20GB still free. I'm using an NVidia graphics card.

If reinstalling can be avoided, it would be really appreciated.

I kind of got this working with help from a friend - by that I mean we managed to get past the "Restoring resolver state..." and successfully log in.

The solution was two-part. I removed all packages related to latest Linux kernel (3.19.0-51) since that got updated with the automatic update that messed things up.

Use tail -n50 /var/log/apt/history.log to see what got updated (adjust -n as needed).

This got me to the login screen, but then I was unable to login. I checked for issues with "Login loop" here on askubuntu.com, but it turned out permissions were okay and the issue was not with lightdm. One of the answers pointed to an issue with graphics, so I looked around for a way to update the graphic drivers without using nvidia-current package.

I followed instructions in this OP http://ubuntuforums.org/showthread.php?t=2263316 with a couple of differences; I didn't pull the latest linux kernel packages and didn't just remove nvidia drivers, I purged them (copied from the link):

sudo gedit /etc/default/grub change line "GRUB_CMDLINE_LINUX_DEFAULT..." to GRUB_CMDLINE_LINUX_DEFAULT="nouveau.blacklist=1 quiet splash nomodeset" #(forces low-level graphics to ensure putty does not give black screen)
sudo update-grub2
sudo apt-get purge nvidia* && sudo apt-get autoremove
sudo reboot

After the reboot I was able to login. I proceeded to install latest nvidia drivers from a .run file as per instructions, but that just threw me back to the login loop issue.

I purged nvidia drivers again, and was able to log in successfully. The downside now is that I can't seem to use the "Cycle multiple monitors" feature of VMWare Player (could be vmware tools issue, but don't want to mess with it now), but at least I can get back to work.

I'll update this answer if I get a solution that works with latest updates.

Ubuntu – Upgraded 12.04 to 14.04, splash gets stuck at “Restoring resolver state…”

I was having this problem on an HP Mini netebook when shutting down the system, if I hit Ctrl+Alt+F7 I would see:

restoring resolver state...

These steps cleared the issue:

sudo vi /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash acpi=force”
sudo update-grub

So basically edit the grub file to add the acpi=force at the end of GRUB_CMDLINE_LINUX_DEFAULT= command.

Ubuntu – 14.04 Freeze on Splash after Installing NVIDIA Drivers

There is a complicated answer here that worked for me: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1362848

I fixed the problem with my nvidia graphic card using the post #15.

Thank you very much kcpr (mkasprzyk5) without your help I would not be albe to fix it.

Here how I fixed in details:

Log out and go to the console:

CTRL-ALT-F1

If (like me) you tried to install latest nvidia driver (nvidia-340 ...), you need to revert back with following commands:

sudo apt-get install ppa-purge
sudo ppa-purge xorg-edgers
sudo apt-get purge nvidia*

Then copy all xorg config files in a temporary dir:

cd
mkdir temp
sudo mv /etc/X11/xorg.conf* ./temp/

Then clean, update, upgrade and reboot the system:

sudo apt-get autoremove
sudo apt-get update
sudo apt-get upgrade
sudo reboot

Go to the console:

CTRL-ALT-F1

Install nvidia 331:

sudo apt-get install nvidia-331 nvidia-prime

Copy the old xorg.conf made by nvidia back in its directory:

sudo cp temp/xorg.conf.nvidia-xconfig-original /etc/X11/xorg.conf

And edit it (I used vi, you may prefer nano):

sudo vi /etc/X11/xorg.conf

To be as the following:

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

Section "Device"
    Identifier "intel"
    Driver "intel"
    BusID "PCI:0@0:2:0"
    Option "AccelMethod" "SNA"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1@0:0:0"
    Option "ConstrainCursor" "off"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

Eventually reboot the system:

sudo reboot

Now I have nvidia set as graphic card and the hardware acceleration works fine.
