Frequent Freezes are Irritating Linux Mint Users
To say that Linux Mint has taken the Linux world by storm and galvanized a gazillion people to try Linux for the first time would be a gross understatement.

Having tried Linux Mint and discovered its user friendly features, millions around the world have abandoned the familiar terrain of their overpriced Windows and Mac OS computers for Linux.

Unlike resource-hungry operating systems like Windows 8 or Mac OS X Yosemite, Linux Mint runs well on old systems that you can buy on eBay or Craigslist for $60-$80.

I run Linux Mint on an old Dell Optiplex 780 core duo PC that I got on eBay.

Getting a first class operating system like Linux with access to tons of free applications for $60 is one of the true miracles of our age.

Linux Mint Freezes – Ugly Wart

But Linux Mint (with the Cinnamon desktop) has a dark, ugly wart that will eventually put off many newbies to Linux if the distribution’s developers continue to ignore a persistent problem.

Frequent freezes on Linux Mint systems (with the Cinnamon desktop) are proving to be more than an irritant.

Every day, Linux Mint users suffer from freezes. They come without warning and bring all work to a grinding halt.

Worse, the freezes now occur multiple times a day lately.

If you’re on a text app like Gedit, you can move the mouse cursor but not much else. The keyboard too freezes.

At first, I blamed the freezes on insufficient memory since I often have multiple browser tabs open and various applications (Gedit, Cherrynote etc) running in the background. And my Linux Mint PC has just 4GB of RAM compared to the 20GB on my iMac.

But then I noticed that even when I had just one or two browser tabs open my Linux Mint PC would freeze inexplicably. I have even encountered freezes when nothing but the terminal was open.

The freeze is is a plague afflicting both the 32-bit and 64-bit versions of Linux Mint (with the Cinnamon desktop).

For the record, I’ve always used Cinnamon as the desktop on my Linux Mint PC (my experiment with Mate on Linu Mint was too short to talk about in any detail).

I hoped that Rebecca would put an end to the freeze issue but my hopes turned out to be in vain.

Having endured multiple freezes daily for over six months, my patience is now nearing its end.

Out of frustration, I switched to CentOS 7 and then CentOS 6 for a few weeks. End of the freeze problem.

But I couldn’t stay away from Linux Mint for long despite the vexing freezes.

How to Unfreeze Linux Mint

I have resorted to two techniques to unfreeze my Linux Mint computer.

The first method that’s helped me to fix a freeze is to press Alt and Tab keys simultaneously.

This technique works 99% of the time, unfreezes the computer instantly and lets me continue my work.

But sometimes the Alt-Tab technique method won’t work.

Then I resort to a different technique – I either open an application from my panel like the RSS news feed or Cherrynote or close a running app via right-click.

This unorthodox method liberates my computer from whatever freezing demon has taken possession of it.

Here’s hoping the smart minds will hunker down and end a problem bedevilling lots of Linux Mint users.

Linux Mint is a superb distro and fixing the freeze issue will enable it to remain the first choice of Linux newbies.

Fix for Webmin File Manager Opening Issue

GUI based web server management tool Webmin is one of the many blessings of the open source movement.

For those not up to speed on command line tools, there’s nothing like Webmin to manage a Linux server.

A module based application, Webmin lets you set up new web sites, delete old sites, set up e-mail, edit files, make changes to IP table rules, examine your logs and so on.

I’ve used Webmin for several years and found it to be a rock solid, reliable control panel that greatly reduces the complexity of managing a Linux server.

Surely, there are a lot of server administrators like me depending on Webmin to get the job done.

But over the last few months I’ve been extremely frustrated at not being able to open Webmin’s File Manager in the Firefox browser on both Windows and Linux systems. When I clicked on File Manager, it would not open because of issues with the IcedTea browser plugin for running Java applets. I would get an error message and the File Manager wouldn’t open.

Here’s the error message, which I have described below only in part:

net.sourceforge.jnlp.LaunchException: Fatal: Initialization Error: Could not initialize applet. For more information click “more information button”.
at net.sourceforge.jnlp.Launcher.createApplet(Launcher.java:746)
at net.sourceforge.jnlp.Launcher.getApplet(Launcher.java:675)
at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:908)
Caused by: net.sourceforge.jnlp.LaunchException: The applet is signed but its manifest specifies Sandbox permissions. This is not yet supported. Try running the applet again, but choose the Sandbox run option.
at net.sourceforge.jnlp.runtime.ManifestAttributesChecker.checkPermissionsAttribute(ManifestAttributesChecker.java:206)
at net.sourceforge.jnlp.runtime.ManifestAttributesChecker.checkAll(ManifestAttributesChecker.java:79)
at net.sourceforge.jnlp.runtime.JNLPClassLoader.(JNLPClassLoader.java:288) …..

Endless frustration!

Except for the File Manager part, the other parts of Webmin and Firefox browser worked fine together.

But since the File Manager is crucial for a lot of tasks (particularly for making quick edits to files) I was often vexed.

I struggled for months, managing as best as I could with the command line.

Solution to Webmin-File Manager-Firefox Issue

Finally, after endlessly scouring the web for a fix I found the solution. Continue reading »

I was watching an old English film The Divorce of Lady X (Laurence Olivier, Merle Oberon, 1938) on my 27-inch iMac via Hulu Plus the other day when a vexing thing happened.

When I expanded the movie on my iMac to full-screen, the below distracting message popped up right in the middle of the screen:

Press Esc to exit full screen mode

Despite refreshing the Firefox browser, I couldn’t get rid off the darn message.

Hulu Plus is not free.

Since I pay $7.99 a month, I’m entitled to a certain minimum quality.

Upon researching the “Press Esc” issue, I realized this was not a rare occurrence with Hulu Plus.
