Re: [Trisquel-users] FN keys doesn't work

[ber . snchzest]

Guys, I tried to do the "sudo gedit /etc/default/grub" manually by searching  
the folder and by editing the file with Leafpad but I can't save it with  
modifications, a message appears saying "Can't open file to write", I checked  
the permissions and it says that the owner is in read and write;group in read  
only;other in read only. I tried to put all acces control in read and write  
but it gives me ": Error setting permissions: Operation not permitted".
