Mint


This doesn’t happen too often.  I had files in folders, in turn within folders.  I needed a nice printout of all the files and folders.  This web page had the solution:

The solution is to use the Terminal, use the command “ls -R > filename”.  The “ls” command lists files.  The “-R” option causes the list to include contents of folders and subfolders.  The “>” symbol redirects the output of the command to a file, named “filename” in this example.  To use this, open Terminal from the menu.  Navigate to the top folder you want to list.  Then run the command.

The result will be a printout of each folder, with the files within listed beneath the folder name.

 

 

This should be easy to do. Then I realized I had not yet ripped CD tracks to MP3 files on Linux or Mint.  I discovered Sound Juice in the package manager, so I downloaded and installed it.  First problem:  ripping to MP3 format requires another library called “lame.”  So I downloaded and installed it.  That got Sound Juice working just fine.  Almost.
Turns out there is a defect of some king that prevents Sound Juice from properly ripping multi-disc sets.  The problem is described on this page:

This may be fixed in the future, but I needed a solution today.  In poking around I noticed that K3b program will rip CDs, in addition to its other functions.  And it works!  Problem solved.

 

 

I am using my Mint desktop with a USB mouse.  Nothing unusual about the mouse.  It is a Logitech wired USB two-button, wheel mouse that I picked up from a local office supply store.  The pointer moves way too fast for my taste.  Even my daughter said it was way too fast.

The solution usually is to adjust the speed sliders in the Mouse section of System Settings.  I already set them to their slowest settings, so something needed to change under the hood.  This web page had the answer:

In Mint I found that the first command to run in terminal is “xinput -list” which will give some information about your pointing device.  Mine says my mouse is “ImExPS/2 Logitech Explorer Mouse”.  Then this command is all it took to slow down the mouse:

xinput -set-prop “ImExPS/2 Logitech Explorer Mouse” “Device Accel Constant Deceleration” 3

With some experimentation I determined that the higher the number at the end of that command, the slower the mouse will move.  For me, “3” worked out nicely.

Another program I really like is Evernote.  This is kind of a handy personal scrapbook.  You can compose in it, or copy text and pictures into it, or even copy web pages into it.  What makes it so special is that it syncs with all your computers.  I can keep working on my projects in Evernote from any computer, whenever I want.

Evernote has a web version and a desktop version.  Desktop versions are available for Windows and Mac.  If you have the Evernote folder that was created during the Windows install process, you can copy that whole folder to Linux Mint and run Evernote with Wine.  Or the easier way is to just use the web version on Mint.  The web version and the desktop version all sync on all your computers.

Here is a screenshot of the Evernote sign-in screen for the web version.  The URL to download Evernote is here:

A good use for Evernote is to keep a to-do list.

Here is a cute little program called Pixie that gives the exact color codes for any color on the screen that you can point to with the cursor (mouse).  This is an old Windows program I have had for several years.  It is really handy when you need to match colors exactly for web page development or other design tasks.

Even though it is a Windows program, there is no install needed.  Just run the .EXE program.  Here is a screen shot of Pixie telling me the color code of the green in the Mint 12 logo on the standard desktop.

The Pixie.EXE download is available from this page:

The initial install of Mint includes a handy little application called Screenshot.  It is very easy to use and in its simplicity only offers a few options.  For example, it will only store screen captures for saving in the PNG format.  That’s OK but sometimes I may want to have JPG, BMP, or GIF formats instead.  Sure, there are other programs that can read PNG and convert to other formats.  It would be nice not to need that extra step.

I noticed another screen capture program called Shutter.  Nice program!  It is still easy to use and offers a lot more functionality, including the capability to crop a captured image.  Nice!

I have included in here a wide capture of my entire desktop.  Since I am running two monitors side-by-side, it captures one image of both.  I am very happy with this set up.

I have been reading about some new work that the Mint folks are doing with Mate and Cinnamon.  They both sound exciting and I will be eager to try them.

Since the U.S. conversion to digital television I have been wanting to try integrating TV reception into my desktop computer.  The first step was to do some research into the TV devices that would have the features I want *AND* work in a Linux environment.  I found this web site very helpful for compatibility research:

http://www.linuxtv.org/

The leading manufacturer of TV reception devices for computers appears to be Hauppauge:

http://linuxtv.org/wiki/index.php/Hauppauge

The Hauppauge company web site is excellent.  It contains lots of detailed information about each of their products, including photos, manuals, and even tips for using their products under Linux:

http://www.hauppauge.com/pages/faq/support_faq_linux.html

In my case I located the Hauppauge WinTV HVR-1600 (model 1178 / version 74021) on Craig’s List for $40.  I believe Hauppauge sells these directly from their web site for $79.

This is a card that fits in a PCI expansion slot in a desktop computer.

The next challenge was to actually install it and get it to work!  This turned out to be a challenge, and maybe a needless challenge had I done things in a different order.  Let me explain…

Linux Mint (and Ubuntu) have the drivers for this WinTV card built into the OS.  In theory, I should be able to power down the computer, install the WinTV in a PCI slot, power up the computer, and start watching TV.  Well, my Mint 12 computer would not boot up with the card installed!  I did more research; I tried lots of things; and nothing worked.  For kicks, I booted my computer (with the WinTV card installed) using the Mint 12 DVD (for a live session) — and the TV worked!  This caused me to conclude that some configuration I did with my permanent install of Mint was creating the problem.  I suspected the NVidia drivers I installed.

So, I backed up everything, reinstalled the TV card, booted with the Mint DVD, and reinstalled Mint 12 from scratch.  And instead of installing the NVidia graphics card drivers, I simply used the default drivers in Mint 12 to configure my dual monitor set up.  I really cannot see a difference between how the displays are now (default Mint drivers) versus how the displays were before (NVidia proprietary drivers).  So I am happy.

By the way, getting my Firefox and Thunderbird configurations set up again the way I had them was amazingly fast and simple in Linux.  Basically it involves copying the .mozilla and .thunderbird old folders (from backup) into the new Mint file structure.  That might be a good topic for another post.

Now with a fresh install of Mint 12, I downloaded three TV packages (via Mint Software Manager):  TV Time, XAWTV, and Me-TV.  Over the past couple of weeks I have gotten comfortable with Me-TV.  The Me-TV interface is fairly intuitive, although there is one feature that would greatly improve it:  An option to re-scan channels.  As the program works today, Me-TV will launch a channel scan “wizard” the first time you launch it.  But that option does not exist after that.  It would be handy to be able to re-scan channels after antenna changes / repositioning.  There *is* a workaround!

Me-TV creates a database file after a channel scan.  If this file is missing, Me-TV will launch the channel scan wizard again to re-create it.  To get Me-TV to rescan the TV channels:

  1. Make sure the Me-TV program is not running (check the status bar at the top of the screen in Mint 12)
  2. Navigate to home/.local/share/me-tv
  3. Delete the file me-tv.db
  4. Launch the Me-TV program again

To make this easier to repeat, I created a link (shortcut) right on my Mint desktop to take me to the me-tv directory (folder).

Although the WinTV HVR-1600 version that I have is cable-QAM (C-QAM) compatible, my current plans are to use it to receive terrestrial digital TV, from an antenna.  Later today I hope to get the antenna installed higher up, in the attic.  But at this moment I have a home-made UHF antenna leaning against the wall in the den, about 6-feet above ground level.  To see how I made this antenna, please visit this page:

Since the TV stations have their towers clustered about 30-miles from me, my reception is not so great yet, until the antenna is mounted higher.  Nevertheless I am amazed it works as well as it does.  Some stations have no drop out!Me-TV in Linux Mint 12

The Me-TV program has a nice “TV guide” section at the bottom, under the screen (see screen shot).  This makes it very easy to quickly see what programs are on, and also what programs are coming up.  There is a record capability which works nicely.  Finally, I can record digital TV!  There are also capabilities to do timed recording (like a VCR in the good ‘ol days).  I look forward to trying that feature soon.
