Kubuntu

Here are the steps I used to get X11VNC working on an Ubuntu (19.10) box. Hope this helps somebody else out there too.

Freeplane, a fork of the mind-mapping program, Freemind, works really well. Except for the fact that in my (K)Ubuntu installation, it sometimes hangs in the middle of editing a node. Once it becomes non-responsive, the only fix is to kill the process and restart the program. The version of Freeplane in Ubuntu 18.04 is 1.6.13. However, the current version (March 2019) of Freeplane is 1.7.7. So, it's highly possible that upgrading Freeplane to the latest version will fix this issue.

I needed to install Windows and downloaded the 4.7GB Windows 10 ISO from Microsoft's website. Since I only had Linux machines at my disposal (and no DVD drives), I had to look to install the ISO on a pen drive. While the purists advocated that I use dd to accomplish this, I found that getting the USB to be bootable was something of a chore. So I looked for a friendlier solution and this is what I found for Kubuntu:

I ran into this error today while running a python program in Kubuntu 18.04 (upgraded from 17.10):

qt.network.ssl: QSslSocket: cannot call unresolved function SSLv23_client_method

followed by a bunch of other similar SSL-related errors. When I checked apt, I found that my openSSL install was fine. A generous guy on IRC informed me that I was very likely missing libraries that the app was looking for. S/he asked me to try installing libssl1.0-dev and voila, it worked.

IOW, run sudo apt-get install libssl1.0-dev to fix the issue.

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.

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:

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.

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:

pecl install mongodb

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:
