[Quick Tip] Disable Apport Error Reporting in Ubuntu 14.10

Last updated: September 26, 2014

Turn off error reporting

This quick tutorial is going to show you how to turn off the Apport error reporting system in Ubuntu 14.10 Utopic Unicorn.

Apport is a system which gathers potentially useful information about the crash and the OS environment. If any process in the system crashes, a dialog pops up and asks user to send error report to help fix the problem.

Error Report Dialog

Reporting bugs is important, it helps improving system stability, but if you’re constantly getting crash report popups, you may want to disable it.

To get started, press Ctrl+Alt+T on keyboard to open terminal. When it opens, paste the command below and run to edit the config file:

sudo gedit /etc/default/apport

You can use gksudo to replace sudo, but install gksu first from Ubuntu Software Center.

When the file opens, change the value of ‘enable’ from ‘1’ to ‘0’ and save it.

Turn off error reporting

After that, stop the Apport process so you don’t have to restart your computer:

sudo service apport stop

That’s it.

Get Back Normal Title Bars For Some Gnome Apps in Ubuntu 14.04

Last updated: September 2, 2014

Gtk3 Apps

In Ubuntu 14.04 and Ubuntu 14.10, some Gnome applications use client-side decorations which don’t work properly in the default Unity Desktop.

The applications with client-side decorations look broken in Unity and they are unresizable. Here are some examples:

Gnome Clock in Ubuntu 14.04

Gnome Clock in Ubuntu 14.04

Gthumb

The Latest gthumb 3.3.2 (gthumb from Ubuntu repositories is old and does not use CSD)

gtk3-nocsd, a hack by one of the LXDE founders, is a small module used to disable the client side decoration of gtk+ 3. It works on most, but not all CSD applications.

After disabled client side decoration, above applications will look like:

Gnome Clock with CSD disabled

Gnome Clock with CSD disabled (Picture was taken in Gnome-Shell)

gthumb with CSD disabled

gthumb with CSD disabled

How to Install & Use gtk3-nocsd

This module has been made into Webupd8 PPA, available for Ubuntu 14.10 and Ubuntu 14.04.

Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, paste the commands below and run one by one:

sudo add-apt-repository ppa:nilarimogard/webupd8

sudo apt-get update

sudo apt-get install gtk3-nocsd

To disable client side decoration, for gnome clock as example:

First run command to edit the application shortcut file, .desktop file under /usr/share/applications or .local/share/applications.

gksudo gedit /usr/share/applications/gnome-clocks.desktop

When the file opens, add env LD_PRELOAD=/usr/lib/gtk3-nocsd/gtk3-nocsd.so to the value of Exec as a parameter, so it looks like:

disable-csd

Save the file and done. Note that gtk3-nocsd does not work for gnome-tweak-tool, gnome-music, etc.

How to Install / Upgrade to GIMP 2.8.12 in Ubuntu 14.04

Last updated: August 26, 2014

install latest GIMP in Ubuntu

The popular GIMP image editor has been updated to version 2.8.12 with a lot of bug fixes. Here is how to install or upgrade it in Ubuntu 14.10, Ubuntu 14.04, Ubuntu 12.04 and their derivatives.

GIMP, GNU Image Manipulation Program, is a raster graphics editor[5] used for image retouching and editing, free-form drawing, resizing, cropping, photo-montages, converting between different image formats, and more specialized tasks.

GIMP image editor

Changes in GIMP 2.8.12:

Core:

  • OSX: Fix migration code for old GIMP directories
  • Fix brush sizes when used from plug-ins
  • Windows: Allow to Explorer-open files with UTF-8 characters in the filename
  • Make XCF loading more robust against broken files

GUI:

  • Make sure the widget direction matches the GUI language
  • Remove the option to disable the warning when closing a modified image
  • Fix canvas overlay widgets (like the text options) for tablets
  • Make DND work between images in one dockable

Libgimp:

  • Make gimp_image_get_name() return the string used for the image title

Plug-ins:

  • Make script-fu-server more secure by listening to 127.0.0.1 by default and add a warning about changing that IP. This breaks the procedure’s API, but for security reasons.
  • Bring back proper script-fu translations

General:

  • Massively clean up and fix the OSX build and bundle
  • Add Jenkins tutorial
  • Documentation updates
  • Bug fixes
  • Translation updates
