How to make a Link in Dolphin file manager

If you run a dual boot Linux system, then you have probably discovered that it is difficult to find what you want on your old Windows file system.  Since Windows cannot “see” your Linux documents and photos, it is sometimes good to store your Linux stuff in the Windows file system where dumb old Windows can find it.  This means that you have to be able to find your way around in the Windows file system.  That is a little tricky and requires lots of mouse clicking.  Using Dolphin, you can not only navigate your Windows system, but you can also make quick “links” to locations that you need to use often so that all those clicks are reduced to ONE.  Start Dolphin now and we will learn how.

Fig. 1

In the left hand column of Dolphin you will see all of your available locations.  To be sure you can see everything, right click in the left column and select “Show all entries.”  A few new items may appear.  Mine looks like figure 1, yours will look different.

“Home” should be at the top.  This is where your Linux documents are stored and it contains several other folders that show when you first start Dolphin.  “Root” is the Linux file system, you mainly leave this alone, but click it now to see what appears in the right column.

In my system, the entry call “HP” is my Windows file system  (your will be different) and the entry call “Docs” is a link to a specific folder inside my Windows system.  With ONE mouse click on “Docs” I can zoom right into my Windows documents.  This would require about 10 clicks otherwise.  If you happen to have a “dead link” that no longer works, you can right click on it and select “Remove” and it will be gone.  Files are NOT deleted, only the link is removed from Dolphin.  If you do not have a “Remove” option, then it is NOT a link and cannot be removed.  I will now remove “Docs” and then put it back step by step…there…. its gone.  Acck!  What have I done??

To make a link, first you have to find a place to which you want to link.  Click the places in the list in the left column until you have found your Windows file system…. you can tell it is Windows because it will have a folder called “Documents and Settings.”   That’s a dead give away.  Ah!! There it is…see figure 2.  Now I am going to click on “Documents and Settings,” then on my user name.  Notice the folder called “My Documents”…. for now, THAT is what I want to make a link to.  Highlight it. (Figure 3)

While it is highlighted, RIGHT click on it and select “Add to Places.” (Figure 4)

In the left column of Dolphin, “My Documents” should now appear.

If you do not like the name that is used in the left column for your new link, you can easily change it.  In the left column, right click on the link and select “Edit” and then type a new name for the link….keep it short.  (see Figure 5)

You now have a direct link to your Windows documents.  You can use Dolphin to copy and move things to and from Windows or you can save Linux documents directly to the Windows file system using this link.  You can make lots of links but keep is simple and make only what you need.  One more thing…. Right Click in the left column and un-check “Show all Entries.”  This will hide the things you don’t need to see all the time.

(Note… if you cannot find your Windows file system in the left column, click on “Root” then “media” and you will find it in there.)

 

How to Copy Photos from Linux to Windows

If you have a dual boot system you may want to copy something from Linux (that you usually use) over to Windows (that you seldom use.) To do this you use Dolphin.LO_50

Launch Dolphin. Click the big K, then system, then Dolphin. The Dolphin window should open showing you the layout of your hard disk.
If you happen to have a Dolphin icon on your desktop already, you can just click that to start Dolphin.

In the right hand column, navigate to where your photos are located.  In my case I have a folder called Pictures.  You may have such a folder with many other folders under it.  Find the pictures that you want to copy.

Now lets find the target location in Windows.  In the upper left corner of Dolphin click on “Split.”  LO_51Another column will open to the right of the first column, the contents will be the same.  You can switch the “focus” from one column to the other by clicking anywhere in the column (one click.)  Try switching back and forth a couple of times to get the feel of it.  Notice that the column that has the focus will have a blue border around it.  Change the focus to the right hand column.

Now the tricky part.  You have to FIND the target folder in Windows where your want photos to be stored.  In the left most column of Dolphin, click on the Windows drive.  The problem is, it probably will not be called “Windows.”  In my case it is called simply “HP” which stands for Hewlitt Packard.  It could be anything.  It will probably not be the top entry, that is usually “Home.”  There is no harm in clicking every entry until you find it.  When you click a location, its contents will appear in the RIGHT hand column, since it still has the focus.  Search until the contents of your Windows disk drive appear in the right hand column.  You can recognize Windows because it usually has a folder called “Documents and Settings.”  Find and open that folder.LO_52

When you open that folder, you should see a list of Users, in my case, the active user is “Tom” so next I am going to open the “Tom” folder.  Underneath “Tom” I have a whole bunch of folders but ONE of them is called “Pictures.”  So I am going to open it.  I cannot accurately predict exactly what your folders will be named but the principle is the same.  Explore around until you find where you want to place the new  pictures.  You may have to dig deeper than I did to find the location.  If you have done all of this correctly, you should see the contents of your Linux folder in the middle column with some picture files showing.  In the right column you should see the contents of your target Windows folder that may also have some files showing.  Now, all you have to do is “drag and drop” the pictures from the middle column (Linux) over to the right column (Windows.)  To do this, left click on a single file and hold down the button, then drag the file over and release the button when it arrives in the right column.  In the illustration below, you can see 3 photos in my middle column and miscellaneous stuff in my right column.  When you release the button a small option box will appear asking you if you wish to “Copy, move, link, or cancel.”  Select either copy or move.

LO_53That’s it!  Pretty easy.  The directions look a lot scarier than it really is.  You can’t really hurt anything so just dive in and practice until you have it down.  You can also copy more than one file at once.  Select several files before you do your final “click and drag.”  You can copy or move as many as you like.  The same procedure is used to copy other types of files.  Its not just for  pictures.

LO_54See, now all my  files are in Windows.

If you wish to close one of the columns, click on “Close” in the upper left corner of Dolphin.  To put Dolphin away, simply X out of it or click File, Quit.

 

 

 

 

Change your physical Keyboard

If your keyboard does odd or unexpected things when you are typing you may have the wrong “physical keyboard” selected.  Here is how to check and fix it.

Click the Big K

Click System

Click System Settings – A big box full of icons appears

Click  “Input Devices” – another box appears showing your various input items, “keyboard” should be highlighted.

By default, it should say something like “Generic 101-key PC.”  This works fine for most people, but modern keyboards have gone wild.  Many have extra keys that do special things.  If such is your case, selecting a different keyboard type may help.

Look at the keyboard model slot…. see the down arrow to the right?  Click it and a list of keyboards will appear.  Scroll up and down and see if your model keyboard is listed. (Look on the bottom of your keyboard…sometimes the model is listedLO_48 there.)  If yours is on the list, select it, then apply settings.  Test and see if that helped eliminate the odd behaviors.  If not, you will have to experiment with other keyboard types on the list until you find one that works well for you.  Remember “Generic 101-key PC” works for most.

If all else fails you can fish for help using Google.  Enter a google search something like “Kubuntu 14 whangho keyboard”  (Put your model in place of wangho).  Vary the search if necessary.  Look for blogs or forums that may have helpful info…. just make sure you find help that pertains to Kubunt 14.  Things vary from version to version.

 

 

 

Change Keyboard Layout

If your keyboards seems to do odd or unexpected things when you are typing you may have the wrong keyboard layout installed.  Here is how to check and fix it.

Click the Big K

Click System

Click System Settings – A big box full of icons appears

Click  “Input Devices” – another box appears showing your various input items, “keyboard” should be highlighted.

Click on Layouts – then check the box “Configure Layouts” – in the big window you should see your keyboard layout named… for US it should be something like “English (US)”

To change the layout….click on +ADD and choose your language and layout.

Click OK, the Apply the settings, then X out of the System Settings.

CPU Speed and Info

You can find out your CPU speed and other info with the following lines simply typed or pasted into the terminal window.

cat /proc/cpuinfo | grep name

or you can try…

lscpu | grep "MHz"

My Trash is empty but I get an error saying it is full.

Several people have reported that when they try to send something to the trash, they get an error saying that it is full.  So they check the trash and it appears to be empty.

You can still delete things by holding the shift key and then hitting delete … but BEWARE that when you do that, it is truly deleted and you cannot get it back.

The following steps may fix your trash problem.

  • Open Dolphin
  • Click on View, then on “Show hidden files.”  Notice that a lot of folders appear with a DOT in front of them.  These are hidden folders.
  • Click on .local, then click on share, then click on trash
  • Inside the trash folder there may be some other folders.  Ignore them.  Look for a file called “metadata”
  • Highlight “metadata” and delete it by holding the shift key and press delete.  It should disappear.
  • Now return to your Home folder, then click on View and uncheck “show hidden files.”

Try sending something to the trash.

 

 

How to number an existing document

Suppose you have a long document that you wrote with LibreOffice Writer (LO) but you forgot to number the pages and now you want to number them.  You can do it.  Here is how.  Take it slow.

  • Open the document
  • Click on Format, then Page, then select the Footer Tab
  • Check the “Footer On” box, then click on “Apply” then click on OK
  • Scroll to the bottom of the first page and put the cursor in the footer area.  This should take one click in that area.
  • Click on Insert, Click on Fields, Click on Other
  • In the Document tab, highlight “Page”
  • In the Middle Column highlight “Page Numbers”
  • In the Right Column Highlight “Arabic”
  • Click on the “Insert Button”
  • Click on “Close”

This procedure will put page numbers in the footer at the bottom of each page.  I tried this procedure with LO documents and also some old documents that were made with other word processors such as Word Perfect 5.1, etc.  Worked fine.

 

How Dropbox Works

Drobbox (DB) can be a little confusing.

When you set up an account with DB, your obtain a “cloud” file storage area on their servers.   You store stuff in your own personal cloud DB using an account name and password.  If you exceed their GB limit, you pay a fee.

If you install DB on your computer,  your then have a “personal” DB on your computer.  It is always just a folder, with various sub folders, located on your hard disk.  A small computer program links your personal DB with your own cloud DB.  The program automatically syncs your personal DB with your cloud DB.  There may be some settings that manage the sync process.

When working properly anything you physically place into your personal DB folder is automatically is transferred to your cloud DB folder.  You can then access it from other devices such as your Ipad.  You can also use a browser to upload and download stuff from any folder on your computer to and from the cloud.  Files are not synced unless they are physically stored in the DB folder on your computer.
Synced means that any time you change a file on your computer, it also changes on the cloud.

When you “share” a file that is on your cloud with a friend, you send them a link that gives them access to that file which they can download or view.  They do this via email or via browser.  If I share a file with you from my cloud DB, it will NOT automatically land on your computer. You have to make an effort to view it or download it on purpose.  It has to be this way or anyone could fill your computer with all kinds of junk without your permission.

To Determine if your DB is working properly, place a new file into your DB folder.  Wait a while.  Then go to the DB website using your browser and see if the file has been transferred there.

On your Ipad, or Laptop, set up DB and use the same account name and password.  That way everything will be synced everywhere….. if you don’t want this syncing feeling…. just access DB from your Ipad or laptop using a browser instead of installing DB on the device.

Should I worry about viruses while using Linux?

Moot question….

You can go to Muon Discover and search for and install “ClamTK” which is the only Linux antivirus program that I know about.  It is pretty pointless to do so.

If someone gives you a disk with a virus on it…. it cannot function.  It will just sit there as you go about your work.

If some one emails you a virus….same deal.

If you go to a malicious web  page, it may crash your browser but no damage will be done.

Technically it is possible to design and distribute a Linux virus…but its effect will be very limited.

If you constantly receive forwarded emails and then you constantly forward them to others, there may be a small benefit in running clam now and then, but since you use Gmail that already has a robust virus filter… the benefit is tiny.  And it you did catch something, it would not benefit you to catch it because it won’t hurt you anyway…. it would simply prevent you from sending it on to others who it may harm.

The most dangerous thing to YOU and ME is sucker plays.  Phishing!!

For example lets say you have an account at the Dogfood bank and you do online banking everyday.  One day someone sends you an email that looks very official stating that there is a small problem with your account and you must click this link that they provide.  When you click the link you are taken to a web page that looks official and almost exactly like your Dogfood Bank page… it looks so close you don’t catch it.  So you enter your name and password to log in and take care of the problem…which seems like nothing.

Then you forget about it.  Several months later….. some money disappears from your account…. not a lot…. you may not notice….. but it happens pretty regular over a period of time and slowly amount to a lot.

You got suckered.  That is worse than a virus.

Kubuntu

Just a quick note to say “thanks!” for all the help and postings about Kubuntu. Transferring from XP to Linux isn’t easy for me, but with your help, it’s going smoothly. I’m 95% there and soon I’ll be able to kick the Microsoft habit for good. Woo hoo! Thanks again.
