comment How to change default locale so new users will inherit it?
Thanks for the response. I included the screenshot to try and give as much information as possible, and you can see there that the English UK option is already selected and has been applied system-wide, but it does not fix the problem - the /etc/default/locale file does not change and new users still inherit the Spanish "en_US.UTF-8." I wish it was that simple, it has been driving me nuts for ages.

comment Text becomes unreadable after high memory usage
Virtually all laptops have temperature sensors. Many of them rely on the operating system checking the temperatures, and controlling the fan(s) as required. Some (like the Lenovo and my old HP/Compaq) have hardware sensors, ie they are just a thermal switch. They do not need a running operating system to ensure they keep cool. If you go into the BIOS and you hear the fan(s) start after a while you can be pretty sure they are hardware controlled. Some machines without hardware sensors run the fans at full speed until the OS takes over, like my Dell PC. FYI the memory test is not CPU intensive.

@Rumesh My guess is if you leave it to run for just an hour it will do quite a few loops. As for the possibility of overheating, I can state that both my current Lenovo and ancient HP/compaq NX have hardware temperature sensors controlling the fan - just a simple on or off, but there nonetheless - which protects the hardware. What make and model is yours?

@Rumesh Without you running the memory test we are all just guessing. I would just set it going some time when you are not going to use it for an hour or so (it only takes 2 minutes to set it going and it will loop forever until you stop it). If it does report errors, it would then be worth re-seating the memory. Be aware that it there is an intermittent problem the test may run for a while before showing errors.Can't edit the above - sorry

It may be that you have faulty memory. It's worth running the memory test. You should be able to access the grub menu on bootup by pressing the shift key while it's booting, then take the option to test the memory. It's extensive and may take a while to complete 1 loop, but leave it running. It sounds as though you may have a fault in a high memory area which is only accessed when a lot is going on, ie high memory usage.

comment How to prompt users with a GUI dialog box to choose file/directory path, via the command-line?
@Wilf The only entry in my /etc/apt/sources.list is virtualbox. I don't know how to check where it was installed from but I think I just type sudo apt-get install yad. BTW it's also shown in the Software Manager and it lists Version: 0.27.0-1~webupd8~utopic0. Also, sorry for the delay replying.

@Wilf Good thinking there. By the way, I'm running Mint 17 and yad can be installed from the Software Centre, too. I don't know if it applies to other releases, though.

@Wilf Yes, yad is Zenity on steroids. Once you get to grips with it, it rocks as it's so flexible. I am a convert. I yadded (couldn't resist that, sorry) a response to the OPs question below, btw.

comment How is the UID of a user passed to sudo, eg in a “sudo mount…” command?
That explains it perfectly, thanks. Please would you post your comment as an answer, so I can mark it as the solution? Thanks.

@muru - sudo bash -c 'echo $SUDO_UID' does indeed return my UID. Is this variable passed to the NFS server somehow? Regarding UIDs and NFS authorization, see chschneider.eu/linux/server/nfs.shtml starting at the second sentence, "Authorization of users is controlled on the clients using the permissions of the files based on user/group IDs. As a result, the mapping of user names to user IDs (and group names to group IDs) must be identical on the server and all its clients (or they must be mapped dynamically)."
