Q Is there a way to delete shortcuts on the Xubuntu desktop?
A (Thanks to PaulW2U in the Ubuntu Forums) You'll find an Icon tab in the Desktop settings. Just untick the icons that you don't want displayed on your desktop. If you decide you want them back, just tick the checkboxes again.
Q A member of my family runs Ubuntu 12.10 and cannot update, upgrade or install anything because his version is not supported any more. Is there a way to upgrade to a LTS?
A (Thanks to slickymaster in the Ubuntu Forums) Please see this thorough tutorial in AskUbuntu: How to install software or upgrade from an old unsupported release?
Q Is there a working OCR program for Ubuntu?
A (Thanks to ajgreeny in the Ubuntu Forums) Instal tesseract. Scan your material at 600dpi for best accuracy, and preferably in lineart or greyscale. Open a command line and CD to the location of your image, then enter this command:
tesseract infile.png outfile
Q All the computers in my household run Linux. There are several users. I want to set up an external hard drive so anyone can use it with no permissions issues.
A (Thanks to weatherman2 in the Ubuntu Forums) Create an ext4 partition which uses the whole external drive. Enter these commands:
ls /media/ubuntu
sudo chmod -R 777 /media/ubuntu/partition-name
Q I have a 1 TB Silicon Power external hdd. It is formatted with gparted, using ext4 and gpt. Everything was working fine till today. I unmounted it with: sudo umount /media/directory
Since then, I cannot mount it by any means.
A The solution was:
fsck.ext4 /dev/sdb1
This cleaned up the corrupt file system.

Tips and Techniques The first branch office
My client is opening its first (one-person, for now) branch office this month. For me, that means a shopping spree: computer, monitor, keyboard and mouse, printer, network cable, jacks, faceplates, switch. (The ISP will provide the router.) Plus, we will set up a fake receptionist's workstation, with surplus computer equipment. Lots of fun, but no Linux.
I just hope someone is thinking about furniture; I don't see that as part of “IT Support.”
