Ubuntu 22.04: ctrl + ; (semicolon) or strg + . (dot) does not work

2022-05-23 von Mario

The shortcut “ctrl+;” or for German keyboard layout “strg + .” inserts the current date into Google or Excel spreadsheets. With Ubuntu 22.04 this shortcut cannot be used. To change this behavior, enter the following command in the terminal:


The IBus GUI opens. Then go to the Emoji tab and remove or change the keyboard shortcuts.

Emoji annotation shortcuts overwrite the shortcuts and therefore it was not possible to insert the current date. After the adjustment, the shortcuts work as usual again.

Ubuntu 22.04: Top Things to Do After Installation

2022-05-14 von Mario

Some recommendations of mine what you can do after installing Ubuntu 22.04 LTS “Jammy Jellyfish”.


1. Remove Snap

sudo snap remove snap-store core18 snapd
rm -rf ~/snap
sudo rm -rf /snap
sudo rm -rf /var/snap
sudo rm -rf /var/lib/snapd
sudo rm -rf /var/cache/snapd
sudo apt autoremove --purge snapd

Prevent repository packages from triggering the installation of snap

sudo gedit /etc/apt/preferences.d/nosnap.pref
    # this file forbids snapd from being installed by APT

    Package: snapd
    Pin: release a=*
    Pin-Priority: -10


2. Install Firefox

Add Mozilla repository.

sudo add-apt-repository ppa:mozillateam/ppa
sudo apt update

Blocks Firefox installation based on snap packages.

echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox

echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | 
sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox

# install firefox
sudo apt install firefox 


3. Rename Network interfaces

Edit the file “/etc/default/grub” and change the line:



GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

Update grub and reboot.

sudo update-grub
sudo reboot


4. Change Boot animation

Edit the file “/etc/default/grub” and change the line:



sudo update-grub
sudo reboot


5. Install Gnome Shell Extension

Install Gnome Shell Extension.

sudo apt-get install chrome-gnome-shell

Open the this link in Firefox and install the Add-on.

Open the address: https://extensions.gnome.org and install the following extensions:

Clipboard Indicator
Status Area Horizontal Spacing 
Arc menu
