A cute little screenshot and annotation tool on Linux

Just download and install the deb file and that’s it!

Build Synergy in Ubuntu 19.04

Synergy software, which shares your keyboard and mouse to multiple computers through the network, is no longer available in the Ubuntu 19.04 repos, so the only remaining option is to build it from source:

sudo apt install qtcreator qtbase5-dev cmake make g++ xorg-dev libssl-dev libx11-dev libsodium-dev libgl1-mesa-glx libegl1-mesa libcurl4-openssl-dev libavahi-compat-libdnssd-dev qtdeclarative5-dev libqt5svg5-dev libsystemd-dev git build-essential
git clone https://github.com/symless/synergy-core.git
cd synergy
mkdir build
cd build
cmake ..
make
sudo make install

That’s it, Enjoy!

Note: After starting Synergy, you don’t have to enter the serial to get basic functionality, just cancel and you are good to go.

Get your Desktop Icons BACK on Ubuntu 19.04 with Nemo

Gnome disabled OOTB support for managing Desktop icons, and is now handled via a gnome shell extension that is missing many features and not quite usable.

The best solution I found so far was to install nemo (file manager on Linux Mint) and make it the default instead of Gnome Files (formerly nautilus) and let it handle the desktop icons as well.

  1. Disable the Desktop Icons extension (from Gnome Tweaks -> Extensions) if it already exists
  2. Install nemo:
    1. sudo apt install nemo
  3. Make nemo the default file manager and disable nautilus control of desktop:
    1. xdg-mime default nemo.desktop inode/directory application/x-gnome-saved-search
    2. gsettings set org.gnome.desktop.background show-desktop-icons false
  4. Add nemo-desktop to your startup items

That’s it, Enjoy!
