Resuming after sleep mode, terminating/hanging up a frozen SSH session in Linux

Submitted by Druss on Fri, 2015-03-20 11:55

So, I am often SSH'd into a remote server from my Kubuntu desktop. I also rarely switch off my desktop and prefer to just hit sleep instead. One of the things that can be annoying when I resume the desktop is that the previous SSH session is now unresponsive/frozen as SSH believes that it is still connected to the remote server while the server has given up on the old session long ago. No amount of CTRL + C or CTRL + Z banging is going to terminate the session which can take an inordinately long wait to time out.

Kubuntu: Audio plays in the wrong tty/terminal

Submitted by Druss on Thu, 2015-03-05 01:18

This has happened to me on a number of occasions where I've found that my system audio only plays when I switch to a different tty. I don't know exactly how to duplicate the issue . But essentially, if I switch from my Kubuntu 14.10 KDE desktop to a different tty (using something like CtrlAltF5) and then switch back to the KDE tty, I find that I can hear no audio. However, if I switch again to the command-line tty, I can hear that audio that ought to have been playing in KDE. Rather weird, huh?

Typing an ellipsis and other exotic characters in KDE/Kubuntu

Submitted by Druss on Wed, 2015-02-18 20:11

I can sometimes be rather picky (some would say 'anal') when I write, for example, an e-mail. I get annoyed if I have to resort to typing three periods for an ellipsis rather than achieving it with just the one character. Doing something with one character instead of three is also a skill that has carved itself a niche in this age of Twitter. So how would one go about it?

Upgrading the Linux kernel in Kubuntu 14.10 from 3.16 to 3.19

Submitted by Druss on Tue, 2015-02-17 02:02

So I've had a graphics issue with my Kubuntu box which relies on an Intel motherboard. While I was hoping to put off the fix until the next version of Kubuntu (out in April), the display bug was getting to be really annoying. I therefore decided to upgrade to the latest kernel immediately.

Google Chrome status bar no longer appearing on hover

So I upgraded my Kubuntu box's kernel to 3.19 and while that fixed my graphics issues, I ran into a new and peculiar issue where hovering over links in Google Chrome failed to display the linked addresses in the bottom of the screen (the status bar). This is apparently a known (Chromium) bug which has still not been resolved. The current recommended workaround is to disable and re-enable hardware acceleration as follows:

Desktop effects were restarted due to a graphics reset

While using Google Chrome on Kubuntu 14.10, the display hung for about 5 seconds before unfreezing with the following notification:

Desktop effects were restarted due to a graphics reset

Once this began occurring with an increasing frequency, I began to do a little digging. Looking through /var/log/kern.log brought the following up:

Eclipse Luna: java: /build/buildd/gtk2-engines-oxygen-1.4.5/src/animations/oxygencomboboxdata.cpp:87: void Oxygen::ComboBoxData::setButton(GtkWidget*): Assertion `!_button._widget' failed.

After installing the shiny new version of Eclipse entitled 'Luna' on a Kubuntu 14.10 box, I found that it crashed/hung when trying to import/clone a Git repository. Starting the application from the command-line triggered the following notice before the crash:

Amarok's folly

Submitted by Druss on Fri, 2015-01-30 22:13

The title sounds like the name of a fantasy novel ... but I'm of course talking (or, as you, stranger of the Internet, will find out, ranting) about the KDE audio player. Amarok is the default audio player for KDE which makes it the default audio player of Kubuntu, my Linux distro of choice. Now, some history before I begin spitting all over you. I usually use Windows as my primary desktop.

Stuck with a VGA monitor (that you love) in the days of HDMI

Submitted by Druss on Fri, 2015-01-30 01:17

So, I have this old Samsung monitor that has served me very well. It's 21" in size and I don't really need anything larger. Only problem is that it is a VGA monitor and uses a VGA cable. My new PC however deems VGA to be of the same archaicity as Morse code and has therefore not deigned to support it. There then I was, stuck with a wonderful monitor that could not be used due to a compatibility issue. Rather wasteful.

Buzzing noise when using the front audio jack

Submitted by Druss on Thu, 2015-01-29 22:26

New Windows 7 system: When I plugged in my headphones into the front audio jack, I immediately started hearing a buzzing and whistling noise in the earpiece. When I switched to the rear audio port, this noise went away. MP3s played clearly on both ports albeit with the buzzing noise in the background when using the front port.
