Navigate to any .lpi file on your disk using the file browser (Nemo). 
Right click on that .lpi, and choose Properties. In the xxxx.lpi 
Properties dialog click on the third button at the top, Open With, and 
choose Lazarus from the list (if it is installed) or use the edit box at 
the bottom of the dialog to locate a Lazarus or StartLazarus executable 
if you have a various Lazarus versions to choose from. You can set this 
choice as the default.
