I just ran into the following error while trying to commit (a previously working project) in Eclipse Neon:

Kubuntu Linux: Increasing volume of audio via HDMI headphone jack

Submitted by Druss on Fri, 2017-02-03 20:56

So, I've started plugging my headphone into my monitor's headphone jack rather than the analog audio ports in my CPU and there's been a drastic reduction in the volume levels. The volume is often insufficient even when everything in my volume settings is maxed out. Here are a couple of things to try out in KDE/Kubuntu/Linux that might help alleviate the situation.

Android (Marshmallow/CM13) installation: Home button and notifications not working

Submitted by Druss on Tue, 2017-01-31 20:06

I wanted to update my old tablet, a Samsung Tab 2, to a more recent version of Cyanogenmod as it was beginning to act up a little. But now that Cyanogenmod is officially dead, the new overlord of Android ROMs is Lineage OS and that's what I installed. All went well and the tablet, now running Marshmallow, was stable and running smoothly. However, there were a couple of glitches.

Kubuntu/Pulseaudio: Record both mic and system audio

Submitted by Druss on Fri, 2016-10-14 19:35

Today, I started dabbling in doing some screen recording in Linux and while I could find programs to record the screen, I couldn't get the audio working as I wanted. By default, the programs record either the system audio, or the mic audio (or if the program is shit, neither); they don't record both the system audio and the mic audio. The fix for this on my Kubuntu 16.04 (Xenial) system which uses the Pulseaudio system to manage audio is as follows:

Installing .NET on Wine (Linux)

Submitted by Druss on Sun, 2016-09-11 23:54

So I've been having trouble getting a Windows program to work in Wine (Windows emulator) on my Kubuntu 16.04 system. It's a simple program but one that requires .NET 3.5. Considering its simplicity, I thought that it'd work fine using just Mono and it did fire up. However, it wasn't terribly usable throwing constant errors and being very buggy. So I had to also install .NET 3.5. timing out during apt-get/aptitude updates

Submitted by Druss on Fri, 2016-09-09 02:23

On a fresh Debian 8 (Jessie) install, I found that I couldn't update the package repository using apt because was always timing out. While I initially thought this was because of a mirroring issue oslt, it turns out that it's because I was trying to access it via the IPV6 that my VPS was using. Turns out that the fix is reasonably straightforward. You simply tell apt not to bother with ipv6 and simply use ipv4 … like so:

echo 'Acquire::ForceIPv4 "true";' >> /etc/apt/apt.conf.d/99force-ipv4

Enabling logging for your MySQL queries from the MySQL prompt

Submitted by Druss on Sat, 2016-06-04 01:44

I usually find it a chore to edit the MySQL conf files (as for one, I often have no idea which my.cnf file to edit!) One way to work around this issue, particularly if you want to change a setting temporarily, is to simply enable the change dynamically via the MySQL command prompt. This can be accomplished by modifying "global" variables which can be listed with commands like so:

Aegir: Site backup error "Could not back up sites directory for drupal"

Submitted by Druss on Sat, 2015-12-19 18:08

If you encounter,

Could not back up sites directory for drupal

when trying to back up a site using Aegir, then this is because there are some permission issues with some of the files in the sites directory.

In my case, these files were in the private/temp/ directory. Listing all offending files can be done by the following command:

MongoDB on Linux with pecl "configure: error: Cannot find OpenSSL's libraries"

Submitted by Druss on Sun, 2015-12-06 21:29

Edit: Skip this and scroll down for a proper fix!

Just tried installing MongoDB support for PHP on Kubuntu 15.10 via pecl and ran into the following error message which caused the installation to fail:

configure: error: Cannot find OpenSSL's libraries

While this can probably be fixed using some magickery, in my case, I did not want SSL support on a dev server. I just wanted to get the fucker up and running. To this end, I discovered that the issue was that I was using:

Kubuntu 15.10 / KDE not automounting partitions

Submitted by Druss on Tue, 2015-12-01 19:42

So I upgraded my Linux box to the latest Kubuntu 15.10 (Wily Werewolf!) and it's been an interesting few days ironing out niggles. One of them has been the missing partition manager icon which (IIRC) was present in 14.04 and where I could control which partitions were automounted at login. From the looks of it, there is no easy solution for this like installing a package or some weird Plasma widget. The only solution I was provided on IRC was the following roundabout-borderline-hack:
