Here is a good tutorial for creating and managing Local Volumes on Linux
Automatic Mounting of NTFS Drive on Ubuntu
To automatically mount an NTFS drive on Ubuntu at startup with RW permissions for all users, add the following line to /etc/fstab:
UUID=146A91D346A61CBD4 /media/DATA ntfs-3g exec,rw,umask=000,users,gid=users,nls=utf8 0 0
where the UUID number for your NTFS partition can be found at the command line by entering:
NXServer 3.5 and Ubuntu 12.04
Sometimes, when accessing a machine with Ubuntu 12.04 (or newer) running NXServer 3.5 from a system running NXClient 3.5 or OpenNX, all you can see is a screen with a desktop picture but no panels or menus.
In this case it is necessary to edit the file /usr/NX/etc/node.cfg on the server in order for it to default the virtual desktop to 2D, without effects.
Almost at the end of the file change the line CommandStartGnome to one of the following:
CommandStartGnome = "/usr/bin/gnome-session --session=ubuntu-2d"
For Gnome Classic:
CommandStartGnome = “/usr/bin/gnome-session --session=gnome-classic”
Problem: it is necessary to connect your local PC to a remote PC using a service that uses an unencrypted connection, or a port number not allowed on the network. Instead, we would like to perform this connection using an encrypted mechanism and an allowed port number.
Solution: SSH Tunneling. This method works as long as the remote computer has an SSH server, and you know which port it is listening to, usually port 22.
Example: the service (such as a Remote Desktop Application) uses port 4000 between the client and server. We want to tunnel this application through port 22, using SSH which is an encrypted mechanism. Here, ‘user’ and ‘server_address’ have to be replaced by your actual user name and name or IP address of the remote computer.
>> ssh -L 4000:localhost:4000 user@server_address
If we needed to use a port different from 22, we have to use the argument ‘-p new_port_number’, as follows (if port 345 is to be used):
>> ssh -p 345 -L 4000:localhost:4000 user@server_address
After the SSH tunnel has been established, the client and server ends of the application (Remote Desktop, for example) have to be launched, and should be able to communicate.

Choosing Primary Monitor on Linux
We use the following command to identify the detected monitors:
Let’s assume that there are two monitors: VGA1 and HDMI1. To set the primary monitor:
$ xrandr --output HDMI1 --primary
Nice PDF Editor for Unix
Pdftk allows you to manipulate PDF easily and freely. It does not require Acrobat, and it runs on Windows, Linux, Mac OS X, FreeBSD and Solaris.
Merge Two or More PDFs into a New Document:
pdftk 1.pdf 2.pdf 3.pdf cat output 123.pdf
or (Using Handles):
pdftk A=1.pdf B=2.pdf cat A B output 12.pdf
or (Using Wildcards):
pdftk *.pdf cat output combined.pdf
Split Select Pages from Multiple PDFs into a New Document:
pdftk A=one.pdf B=two.pdf cat A1-7 B1-5 A8 output combined.pdf
Rotate the First Page of a PDF to 90 Degrees Clockwise:
pdftk in.pdf cat 1E 2-end output out.pdf:
Rotate an Entire PDF Document’s Pages to 180 Degrees:
pdftk in.pdf cat 1-endS output out.pdf
Encrypt a PDF using 128-Bit Strength (the Default) and Withhold All Permissions (the Default):
pdftk mydoc.pdf output mydoc.128.pdf owner_pw foopass
Same as Above, Except a Password is Required to Open the PDF:
pdftk mydoc.pdf output mydoc.128.pdf owner_pw foo user_pw baz
Same as Above, Except Printing is Allowed (after the PDF is Open):
pdftk mydoc.pdf output mydoc.128.pdf owner_pw foo user_pw baz allow printing
Decrypt a PDF:
pdftk secured.pdf input_pw foopass output unsecured.pdf
Join Two Files, One of Which is Encrypted (the Output is Not Encrypted):
pdftk A=secured.pdf mydoc.pdf input_pw A=foopass cat output combined.pdf
Uncompress PDF Page Streams for Editing the PDF Code in a Text Editor:
pdftk mydoc.pdf output mydoc.clear.pdf uncompress
Repair a PDF’s Corrupted XREF Table and Stream Lengths (If Possible):
pdftk broken.pdf output fixed.pdf
Burst a Single PDF Document into Single Pages and Report its Data to doc_data.txt:
pdftk mydoc.pdf burst
Report on PDF Document Metadata, Bookmarks and Page Labels:
pdftk mydoc.pdf dump_data output report.txt
HP Elitebook 8560p and Linux Mint 10
I posted some basic instructions to get Linux Mint 10 working on the HP Elitebook 8560p here.

Sharing folders between Ubuntu 10.04(host) and Windows XP(guest) with VirtualBox
1) Share a folder normally in VirtualBox and remember the name you assign to it, NOT the path but the name.
2) Once in Windows go to the command prompt and type:
c:\> net use e: \\vboxsrv\NAME
3) Now you can use folder NAME in Windows as drive E:
