Microsoft True Type Fonts

sudo apt install ttf-mscorefonts-installer

Terminal Font Preference

Ubuntu Mono Regular 10 is currently my favorite setting. It's closest to the appearance of the normal font used by default in PuTTy on Windows.

Color Schemes

I really like the Hybrid and Monokai Dark colors Schemes. Easiest way to get it is using the links below:


wget -O gogh https://git.io/vQgMr && chmod +x gogh && ./gogh && rm gogh

Gnome Alt-Tab Changes


I do not like how Gnome 3 groups applications when using Alt-Tab. The changes below will revert back to the traditional behavior but still allow you to switch just applications by using the Super key instead of Alt.

gsettings set org.gnome.desktop.wm.keybindings switch-windows "['<Alt>Tab']"
gsettings set org.gnome.desktop.wm.keybindings switch-windows-backward "['<Shift><Alt>Tab']"
gsettings set org.gnome.desktop.wm.keybindings switch-applications "['<Super>Tab']"
gsettings set org.gnome.desktop.wm.keybindings switch-applications-backward "['<Shift><Super>Tab']"

Gnome 3 Extensions

Dash to Panel

  • Go to Tweaks, Top Bar, set Clock / Date to On.

Arc Menu

  • Go to Tweaks, Extensions, Arc Menu (Settings), set "<Ctrl>Escape" as the custom menu binding.



Use the PPA below to install the latest version of Remmina:

sudo apt-add-repository ppa:remmina-ppa-team/remmina-next
sudo apt-get install remmina remmina-plugin-rdp libfreerdp-plugins-standard

L2TP/IPSEC and OpenVPN support using Network Manager


You need to install some packages and disable the included xl2tpd daemon due to some bug supposedly.

sudo apt install network-manager-l2tp-gnome network-manager-openvpn-gnome
sudo service xl2tpd stop
sudo systemctl disable xl2tpd

When making an L2TP/IPSEC connection, the following settings need to be made:

Click IPSec Settings…
Click the box for “Enable IPsec tunnel to L2TP host”
Enter the shared secret into the Pre-shared key field.
Leave the Gateway ID field empty.
Expand the Advanced options area
Enter “aes128-sha1-modp1024” into the Phase 1 Algorithms box.
Enter “aes128-sha1” into the Phase 2 Algorithms box.
Leave the box checked for “Enforce UDP encapsulation”.
