comment Text becomes unreadable after high memory usage
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.

comment How is the UID of a user passed to sudo, eg in a “sudo mount…” command?
@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)."

comment Can't write to external hard drive
Possible permissions problem. Try sudo touch path/to/mount/point/mynewfile and see it it works. If so its ownership. Who do you want to have access to the drive?

Sorry, I missed that. At 26 bytes there is nothing other than "in underwear and a shirt?" in the file so nothing to worry about there. What about owner and group info?
