Add/remove Startup Applications in Ubuntu 11.10 January 17, 2012

Posted by viboon in : Ubuntu , add a comment

Copy or delete the program you want to automatically startup everytime a user logs in from /usr/share/applications/program.desktop to /etc/xdg/autostart folder.

For example, if you wish to start Firefox when you login, you have to run a following command to copy firefox.desktop to the /etc/xdg/autostart.

sudo cp /usr/share/applications/firefox.desktop /etc/xdg/autostart

To remove the program from the startup application, you have to remove the file as follows:

sudo rm /etc/xdg/autostart/firefox.desktop

Clean recent documents opened in Ubuntu 11.10 January 16, 2012

Posted by viboon in : Ubuntu , add a comment

Delete recently-used.xbel:

rm ~/.local/share/recently-used.xbel

Create a new empty file:

touch ~/.local/share/recently-used.xbel

Make sure the new file cannot be modified:

sudo chattr +i ~/.local/share/recently-used.xbel

now, your display of recent items is gone.

If you want to revert back, remove the i attribute of recently-used.xbel:

sudo chattr -i ~/.local/share/recently-used.xbel
