Problem With Font Color In Ubuntu 12.04

Sometimes when you change setting to make your themes nicer, it makes your fonts can't easily read. I found this solution.

 mv /home/user/.config/dconf/user /home/user/.config/dconf/user.old

All your setting will lost but you'll get the contrast.

How To Remove Envelope Icon From Top Panel Ubuntu 12.04

If you don't like to use the envelope ( like myself) just remove it from the panel. Code:

sudo apt-get purge indicator-message

or just open the Ubuntu Software Center and search for "indicator-messages" then uninstall.
But i prefer the apt-get.

Ubuntu 12.04 Black Screen After Logout

There were lots of suggestions and answers I found regarding this matter but the one that worked on my end was a very simple one. It was all about the screen display resolution. My laptop has a standard 1366 x 768 (16:9) resolution. For some reason this was changed to 1360 x 768.
The change is very minor but this, in fact, was the cause on why I get a black/blank screen when I logout. After restoring to the original resolution, everything is now back to normal and working as it should be.

Go To System Setting

Choose Display

ok.

Change The Purple Background (Splash Screen) Ubuntu 12.04

In this tutorial we will see how to change the background image (splash screen) of the GRUB boot loader under Ubuntu 11.10/12.04 or older.

When you start your system, a boot menu will show up containing an ordered list of operating systems and kernels. This boot menu is black by default and can be customized as follows:

Start the Ubuntu terminal and install first the grub2-splashimages package with this command:

sudo apt-get install grub2-splashimages

GRUB spalsh images are stored in the /usr/share/images/grub folder, you can access it with this command:

sudo nautilus /usr/share/images/grub

If you want to use a custom image, make sure it is in the TGA format, then place it in that folder. After deciding which image to use as splash screen for the GRUB2 boot loader, edit now the /etc/default/grub file with this command:

sudo gedit /etc/default/grub

At the end of the file, add this line:

GRUB_BACKGROUND=/usr/share/images/grub/YOUR-IMAGE.tga

Replace YOUR-IMAGE.tga with your custom image name.

When you finish, press CTRL+Q and save your file. Run now this command:

sudo update-grub

Restart now your computer to see if changes are successful (hold down the SHIFT key to bring up the GRUB boot screen while rebooting). Source

Disable Apport Error Report Dialog in Ubuntu 12.04

In fresh Ubuntu 12.04 installation, it keeps popping up annoying apport error report dialog on every log-in even after sending the error report. This simple tutorial will show you how to disable this dialog in Ubuntu.

Open up terminal from the dash home or press Ctrl+Alt+T, edit “/etc/default/apport” file with this command:

sudo gedit /etc/default/apport
Set enable=0:
enable=0

Save the file, and done!

What is the HUD?

The HUD or Heads Up Display is a search-based alternative to traditional menus and is a brand new feature in Ubuntu 12.04.

Some apps like Gimp or Inkscape have hundreds of menu items. If you're using apps like these, you may remember the name of a menu option, but you might not remember how to find it in the menus.

Using a search box can be quite a bit easier and even faster than navigating complicated heirarchies of menus. The HUD also can be more accessible than normal menus as some people are unable to precisely control a mouse pointer.

It's easy to try the HUD:

Tap Alt to open the HUD.
Start typing.
When you see a result that you want to run, use the up and down keys to select the result, then press Enter, or just click your desired search result.
If you change your mind and want to exit the HUD, simply type Alt again or Esc. You can also click anywhere outside the HUD to close the HUD.

The HUD keeps track of your search history and adjusts the search results to be even more useful the more you use it.
