There are two locations where you can define the button's location: dconf and gconf.

On my hp Spectre x360, the Ins key is only reachable via the Fn key as in Fn+PrtScr.

So I wanted to swap both keys. System-wide - so not only in X (using xev).

I finally found this which suggested the following procedure:

Steam has the bad habit to not run after upgrades of the Steam software.

To install Puppet on CentOS 7, you can basically follow these instructions.

Detect new disk size

This label printer doesn't work out of the box under Linux. There are some instructions over at ubuntuforums.org, but they're missing something for the latest Ubuntu Oneiric Ocelot. These instructions should work:

To enable most .plgx-Plugins, you need to install the mono-gmcs-Package. For newer versions of KeePass, use mono-dmcs.

If you want to find out from which PPA a specific package was installed or what other PPAs hold it, you can use the following command: (found at superuser.com)

After an upgrade to Ubuntu Lucid Lynx, all Samba shares were missing symlinks, esp. symlinks to directories outside the share.

To export a list of all installed packages, you can use the following command:

• Download: citrix.com (preferably .deb format)

To merge multiple (similar) video files into one big file, there are different ways.

If you wish to change the behavior upon pushing e.g. the power button, you can edit the config files located in /etc/acpi/events/. To disable the power button, you would edit the file powerbtn there and change the action line to:

You need the following libraries to successfully compile Kismet:

If you are on a 64bit system, you might sometimes stumple upon 32bit programs which need several libraries of which are no lib32-packages. A good example is the Amazon MP3 Downloader.

If your flashplugin only recognizes the very first mouse click and then seems to ignore the mouse completely, just click somewhere outside the area where the flash script is (e.g. on the webpage background) and then flash will recognize the next click.

One huge problem in a standard Ubuntu install is that not all programs are actually using the PulseAudio daemon but instead still use ALSA. This is especially true with the flashplugin. Since PulseAudio and ALSA can't use the hardware device at the same time, they block each other which leads to hangs and maybe even crashes of programs (e.g. browser).

Java crashes with EXCEPTION_ACCESS_VIOLATION (0xc00000005)

The default soundcard to be used with ALSA is that with the index 0 in /proc/asound/cards. Usually this is the first found sound device.

Desktop Drapes

Enable in Ubuntu

The tools you need are described on blog.joff3.com. There's also the nice youtube-dl package. One thing I noticed: the ffmpeg command there re-encodes the audio which might loose some quality. To just dump the audio off the Flash video, use:

If you have no sound in Flash videos but in all other programs, there are two possibilities:

1. the PCM output is set to silence
   • check volume setting with alsamixer
2. you might have a second audio device (e.g. a Webcam with a microphone) which gets preferred by ALSA
   • fix it by unplugging it, or
   • force ALSA to use another device, see ALSA FAQ#26
   • set Skype → Options → Sound Devices to [ ] Allow Skype to automatically adjust my mixer levels
3. some sound via PulseAudio is currently playing (see ALSA → PulseAudio for Flash and others)

Bug report is #396558.

apt-cacher and apt-cacher-ng both act as a proxy between apt-get or aptitude and the Debian repositories. It stores the packages upon first request and loads them from cache on further ones. If you have 2 or more Ubuntu PCs in your network, you can save a massive amount of bandwidth with it.

Install the packages colormake and colorgcc. Then create the following alias:
