Modifying the keyboard layout

I'm uncertain if this meets your request (because I can't read the page), but take a look at http://www.gerdi.net/

There are some controls which might help you in System->Preferences->Control Center->Keyboard Preferences too, if you haven't looked at them already.

I attempted to modify the keyboard layout as Simos Xenitellis suggested, but I am unable to save the file, and if I attempt to replace the file with a modified version through copy and paste, I am told that I have no permission to change it or its parents folder. How do I fix that?

The specific file is protected by your system. It is important when you do testing, to save a backup of the file so that you can revert back if something goes wrong.

I recommend that you check
https://help.ubuntu.com/
and in the Advanced section it mentions how to use the command line and "sudo". You need to use "sudo" to get temporary administrative privileges so that you can edit the file.

In a nutshell,

To make a backup of the Arabic keyboard layout file
sudo cp /usr/share/X11/xkb/symbols/ara /usr/share/X11/xkb/symbols/ara.ORIGINAL

To edit the Arabic keyboard layout file
sudo /usr/share/X11/xkb/symbols/ara

To revert back to the backup copy of the Arabic keyboard layout file
sudo cp /usr/share/X11/xkb/symbols/ara.ORIGINAL /usr/share/X11/xkb/symbols/ara

You will be asked for your password when running the above lines.
Once you make a change in the "ara" file, you need to go to the Keyboard Indicator, remove the Arabic layout and add it again. In this way it will refresh it for you and you do not have to reboot.
Make sure you understand these commands. Try with a small change first.
Good luck!

I did that, made a small change, the "division" to U+00AB and the "multiply" to U+00BB and saved it. The problem I got was after removing the Arabic layout from the Keyboard Indicator and adding it again, I got an error saying "Error activating XKB configuration." On the bottom of the error dialog it says I should include this if I report this as a bug:
"The result of xprop -root | grep XKB
The result of gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd"

I'm actually glad I got this far, but I don't know why this reported an error. Was there an extra thing I had to do? Or did I have to enter the symbols in the file in a different form than the Unicode form? Because the "multiply" and "division" where just like that and not in Unicode format.

Thanks again Simos

Can you please show me the change you made?
You can post the lines that you added or changed.

aha! I found it, I used U+00AB and U+00BB when I should have used the utf-16 format which is 0x00AB and 0x00BB.

That was the "bug". It works fine now. Thanks

Thanks Simos Xenitellis, that solved my question.

If you made some Ottoman letters please send the layout to me. Thanks..

Is it possible that in the most recent version of Ubuntu these file locations have changed? I cannot find them at that location. There is no symbols folder. If anyone can help with this, thanks.

Make sure you have the "X11" in the path has a capital "X" instead of a lowercase "x".

I figured out my problem. I was reading from two sets of instructions and the other set was sending me to the /etc/ folder instead of the /usr/share/. Thanks for the response.
