Installation:
Open the terminal and type in:

My setup:

I installed Linux Lite 2.0 on a PC on which I previously had Windows XP installed (my son suggested I try migrating to Linux for this machine so I figured why not...I have never worked with Linux before and here is a good opportunity).  It is merely an extra computer in the house that I use since others in the house are so often on my better computer which has Windows 8.1 installed.  Anyway, there are some files that I use quite often that I need to be able to access using both computers.  To do this, I have an SD card installed on an Epson Work Force 610 that is installed as a network printer.  The SD card is formatted in FAT32.

Since installing Linux Lite 2.0, there are some problems I cannot resolve without causing other problems.

a)  I can get to the memorycard via the network on Linux Lite 2.0 and can copy from and paste to the card using the file explorer type software.  But, other programs, such as LibreOffice, the text editor (Leafpad?), and GIMP cannot open files on the card this way or save files to the card.  The programs just do not seem to recognize the card in this setup.

b) I have read that to overcome a) one needs to mount the memorycard.  To do this, I have been trying to modify my fstab file.  Using the following:

//192.168.61.8/memorycard /home/rob/memorycard cifs credentials=/home/rob/.smbcredentials,sec=ntlm,rw,user,noauto,uid=1000,gid=1000 0 0

I can get the memorycard mounted such that the programs can open files from the card and can save new files to the card.  The problem is that if I try to save a file having the same name as a file already there (overwriting or just hitting the save button), none of the programs will let me.  When I try in Leafpad, it says “Can't open file to write.”  When I try in LibreOffice, I get three errors: 1)  “Error saving the document Procedures3:General input/output error while accessing”, 2) “Error saving the document Procedures3:General input/output error while accessing”, and 3) “Error saving the document Procedures3:General Error. General input/output error.” (all very similar but all three come up).  Furthermore, the file that I am trying to overwrite gets corrupted and useless but if I try again to save the still open file as another name, it will do it.  GIMP gives similar results.

c)  Thinking that the problem might be the fact that I am mounting it using cifs as opposed to vfat, I have made attempts at trying to mount the memorycard using:

//192.168.61.8/memorycard /home/rob/memorycard vfat credentials=/home/rob/.smbcredentials,sec=ntlm,rw,user,noauto,uid=1000,gid=1000 0 0

I have also tried other iterations using various options.  The problem I have with the above is that it won't mount.  I keep getting the following:

mount: special device //192.168.61.8/memorycard does not exist

Now clearly it exists because I can get it to mount using cifs.

So my ultimate question is how can I get this SD card mounted so that the programs can properly overwrite existing files, so I can modify files and merely hit the save button when using the Linux programs?

My current workaround is to have XP loaded in VirtualBox and use that to access things.  But that kind of defeats the purpose of using Linux Lite 2.0 so I would really like a better solution.

Hi
Wondering if anybody has successfully installed cryptkeeper.

An icon should show on the panel when activated. For me the icon do not show on the panel and therefore I can not operate cryptkeeper.
This problem was an issue also for Ubuntu, but after some manipulations with an editor it showed up on panel.

Can someone explain to me what GRUB and ROOT are?
What do they do?
I am a bit of a Linux noob.

In LL 2.0 What is the difference between unmounting and ejecting a usb flash drive?
Which is safer to do before the flash drive is physically removed from the usb port?

What is a Keyring?
How do I make it not appear first thing after boot up and the PC is on?
There is already a password for my wifi, why does it ask for another?

Greetings!

I really need to know how to use my Laptop to work with a Projector in my presentation this coming weekend. I think I have two options:

1. Learn how to make 'F10' (Lenovo G405's 2nd screen/projector) work with any projector.

2. Dual boot with windows Os
concerns:
    I need to preserve my current LInuxlite setup & files

Questions:
#1. Is there any known way to make linux works with any projector?

#2. How to restore previous Linuxlite system(not from dual boot system) to the new linuxlite installed in a dual boot system with windows?
    Whats the difficulty level on this task? Im completely newbie with Linux though I can work with its basic functionality - email, browse, create documents, presentations, etc... except for administration tasks - i,e backup, repair & troubleshooting, etc...

I look forward for any help. My report will be on August 9 and I need to decide while I can't afford to mess with my laptop this time.

Many thanks in advance.
