comment Can't connect to windows 7 ad-hoc network
WPA2-Personal should work. Did you have just standard characters in the key: upper and lower case a-z and numbers 0-9? Other things to try are using WPA instead of WPA2 and even trying WEP which, while no longer secure, is still better than nothing.

comment Can't connect to windows 7 ad-hoc network
If you have removed the key phrase and you can now connect successfully, that indicates that the issue is with the key. There used to be problems entering keys as there were two methods, basically text and hex. Normally this is no longer a problem, everything is entered as text. I would suggest trying a simple key to begin with to see if you can get that to work. Then try successively more complex ones.

comment Why does Software Centre ask for root password when the default is for root to be disabled with no password set?
AFAIK only to allow my normal ID to SUDO without a password

Thanks for the info re policykit. I've mainly used Debian and SUSE in the past so I'm happy with command line installs but it bugs me why Software Centre isn't working as expected.

comment Why does Software Centre ask for root password when the default is for root to be disabled with no password set?
No, policykit-1-gnome is installed. Every time I try to install anything, it asks me for the root password. I could only install from the command line until I added a password to root. I have changed SUDO so that my normal user login isn't asked for a password when doing SUDO - would that effect it?

comment Sound not working with an SB Audigy card
I have the same problems. I've always had problems with sound. In the past, the only Distro that worked was SUSE. I use a Creative Live1024 card. I've tried every mode and combination I can think of.

Can you provide more detailed instructions? How do I know if I'm using pulseaudio?

comment What strategies (especially available software) do you use to keep passwords safe?
2 Years on and LastPass is still a world-leading product. However, it is for browser passwords only on Linux. On Windows, it does have some additional utilities that manage WiFi and some other passwords.

@Scaine: This is no longer the case. There are versions of applications on several platforms now that support v2 databases including Linux. "keepass2" for example, is available in the Ubuntu repo's.

comment How do you set requirements (such as minimum length) on passwords?
You've listed pam_unix(5), the correct page is pam_unix(8) linux.die.net/man/8/pam_unix. In fact, the online versions of the manpage, for some reason don't seem to list the important section on the "obscure" parameter - the one that I've included in my answer. If you do a man pam_unix, you will be able to see it though.
