Preferred Applications
This feature is located in Menu -> Control Center -> Preferred Applications. It grants you access to the applications that are run by default whenever your system makes specific calls. For example, in the screenshot below I have changed my preferred web browser to Google Chrome so that anytime I click on a hyperlink it will no longer be opened with Firefox. I chose Google Chrome because of the effortless bookmark/extension sync feature across Windows/Linux platforms if I ever need to switch back and forth.
Configuring the Boot Loader
Some of you may not be happy with Linux Mint 11 being the default operating system that is booted into or may want to change the time it takes for GRUB2 to boot into one of the operating systems. To do this go to Menu -> Control Center -> StartUp-Manager.
First you can change your default operating system that is highlighted by GRUB2, so that you automatically boot into it from the boot loader. You may also change how long it takes to boot into your default operating system using this program.
The "Timeout" option indicates how long the boot loader screen will stay active giving you the option of selecting an operating system. If you would like to automatically boot into the operating system that you have selected enter "0" for the time. Otherwise you can pick a default timeout that you would like. However, if you would like to set it to not time out at all then there are some *slightly* more complicated steps to follow below:
Start by opening a terminal and typing the command:
gksudo gedit /etc/default/grub
Here we can change the time to infinite and do some more advanced configuration options as well. By default this is the top few lines of my grub:
If you want to change your GRUB timeout from x to infinite change the following line:
GRUB_TIMEOUT=-1
If you would like GRUB to remember operating system you booted into last and highlight it automatically on restart, change the first line and add this one after it (both case sensitive):
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
Now, if you've made any changes in gedit hit the save button and then type this for following for your changes to take effect:
sudo update-grub
Restart and your changes should now be in place. You can test the GRUB_DEFAULT and GRUB_SAVEDEFAULT by setting a low GRUB_TIMEOUT and booting into different operating systems and rebooting.
Starting a GUI-Based Application on Boot
It's possibly you may want to start an application that has a GUI when starting your system to help automate your system a little. You may also have one that is being run automatically that you want like removed. Go to Menu -> Preferences -> Startup Applications.
From here we can either add or remove an application. For the sake of the tutorial, I'm going to add a Minecraft server so that I don't have to start it up every time I turn my computer back on. Start by clicking Add and entering the name of your application. Now we want to type the command to execute the application from terminal. For some samples, check out the Native Games for Linux Mint 11 section on menu commands. My Add Startup Program looks like the following:
Name: Minecraft Server
Command: java -jar /home/user/minecraft_server.jar nogui
Or if you'd like another example of how to start Pidgin when your system starts up:
Name: Pidgin
Command: pidgin
