Here is the copy of apport.log. Can someone help me understand and help me troubleshoot ? This is crashing almost everyday.

After following a suggestion in the comment to remove compiz I lost my launcher. Now the question is kept on hold asking to upgrade ubuntu. Now my question is does upgrading my Ubuntu to 15.04 and then to 15.10 and there to 16.04 LTS help me in getting back my launcher ?

Also please help me on upgrade path as I would like to update using DVD because online update if in case of internet and power outage could cause permanent loss of data. Please suggest on upgrade path and method.

    What Ubuntu version is this? What did you do prior to the problem occuring? Do you experience the crashes running any other operating system, can you reproduce it running the live image?

It seems here that the error comes from compiz with wrong settings, so I advise you to uninstall and reinstall compiz:

sudo apt-get purge compiz*
sudo apt-get install compiz* --fix-missing

It's happening because hud-service is trying to load, but it's getting a segmentation fault interrupt. You can disable hud-service with:

sudo chmod -x /usr/lib/i386-linux-gnu/hud/hud-service

Then, reboot.

You can find more information about HUD-service here.

As your comment indicates that you are using Ubuntu 14.10 (which is out of support) my best guess is that you are affected by a bug that was fixed quite some time ago for a currently unsupported version of Ubuntu. I suggest that you update to a currently supported version. Instructions for doing so can be found here. Another option would be to boot from a live media of a supported version such as 14.04 or 16.04

    Your version of Ubuntu is 2 years old and is not an LTS release, so it is no longer supported by Canonical or Ask Ubuntu. If you want tech support, please consider upgrading to an up-to-date version that is still supported.

The errors you are trying to fix today (October 9, 2016) are coming from (August 2016). To fix the problem you need to find the right error messages first.

Try looking in 'var/log/syslog' for starters.

Edit 1 - Reinstall Unity

Based on comment below this is the recommended course of action:

sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install unity

  • I followed one of the suggestion given sudo apt-get purge compiz* sudo apt-get install compiz* --fix-missing The first one removed my launcher. Now If I run the second it's throwing error. I created a new post for it . How to get my launcher back ? askubuntu.com/questions/834869/ubuntu-14-10-launcher-missing
