I run Ubuntu 12.04 on my laptop, with an encrypted home folder + swap partition. Before I had this encrypted setup, I used to have my hibernation enabled. I found this documentation on how to enable hibernation with an encrypted swap.
Now the thing that bothers me by using the solution as given in the documentation, is that apart from having to type my password to login to my user account, I have to type separately a password to mount my swap partition.
A possible solution to this is (is it?) to enable my user account to automatically login (so as to skip the login screen) and view the mounting of the swap partition as an alternative login screen. Note that I am the only user of my laptop.
The only drawback to this method is that after 3 password attempts the system anyway continues booting, though without mounting the swap partition. Leaving my desktop freely available to anybody.
As I would like to use hibernation while having only to type my password once at startup, my question thus is whether it be possible to:
- Or make the password-attempt count infinite
- or alternatively let the system reboot itself after three attempts (starting the cycle over again)
and if this is possible
- whether it would pose a security breach not thought of by me
and if not possible: Whether there would be another creative alternative allowing me and other users to use hibernate in combination with encryption without having to type two pass phrases at boot.
Thank you very much for any help!
