Ubuntu Unity Desktop uses *.desktop files set the default programs for file types. In order to achieve what you desire you can create a custom *.desktop file for google-chrome just for your user.
This will take a couple of steps:
1. Verify Default Program
Verify that google-chrome.desktop is your default program for opening links:
In Terminal enter: cat ~/.local/share/applications/mimeapps.list.
Output should be something like this:
[Default Applications]
text/html=google-chrome.desktop
x-scheme-handler/http=google-chrome.desktop
x-scheme-handler/https=google-chrome.desktop
x-scheme-handler/about=google-chrome.desktop
x-scheme-handler/unknown=google-chrome.desktop
x-scheme-handler/mailto=google-chrome.desktop
text/x-c++src=gedit.desktop
<p><code>[Added Associations]
text/x-c++src=gedit.desktop;</code></p>
If like in the example google-chrome.desktop is handling the web links then proceed as described. If not you need to set the default program first.
2. Create Custom *.desktop File
Creating a custom google-chrome.desktop file at ~/.local/share/applications/ based on the original /usr/share/applications/google-chrome.desktop file.
In Terminal enter:
cp /usr/share/applications/google-chrome.desktop ~/.local/share/applications/
Doing this you will only change the settings for your user and not all users in the machine.
If a *.desktop file name from /usr/share/applications/ is duplicated at ~/.local/share/applications/ then the local one takes priority.
3. Edit new *.desktop file
This file will contain many lines for names of options in different languages. We will need to edit all lines starting with Exec=.
Example from my computer at: /usr/share/applications/google-chrome.desktop
Exec=/usr/bin/google-chrome-stable %U
Exec=/usr/bin/google-chrome-stable
Exec=/usr/bin/google-chrome-stable --incognito
In the new file at ~/.local/share/applications/ change these lines by adding the option --profile-directory=Default.
Exec=/usr/bin/google-chrome-stable --profile-directory=Default %U
Exec=/usr/bin/google-chrome-stable --profile-directory=Default
Exec=/usr/bin/google-chrome-stable --profile-directory=Default --incognito
This will make it so every time you open a link it will be opened by the Default user.
Different User
The option --profile-directory= can be set to the name of anyone folder at ~/.config/google-chrome/ that holds user configuration. Examples:
- Default
- Profile 1
- Profile 2
- etc...
Example:
Exec=/usr/bin/google-chrome-stable --profile-directory=Profile\ 1 %U
Exec=/usr/bin/google-chrome-stable --profile-directory=Profile\ 1
Exec=/usr/bin/google-chrome-stable --profile-directory=Profile\ 1 --incognito
Observe the backslash\ in Profile\ 1 to indicate the folder name includes a space.
