Ubuntu is a linux distribution derived from debian. It's a very nice plug&play OS with all features I need.
- cat /etc/os-release
- cat /etc/lsb-release
- lsb_release -a
- Show the currently installed version. os-release has most information.
Modfications made
The few things I needed to tweak are listed here.
NetworkManager
NetworkManager is a bad idea, just use /etc/network/interfaces and /etc/resolv.conf to configure your network. Having a DHCP server to supply network configuration is fine, everything else is making things complex. You may need to install ifupdown and disable the netplan thing to achieve this.
- Uninstall dhcpcd
- Uninstall openresolv
Settings GUI
One day I could not start the settings GUI anymore. Removing the unity-control-center fixed the problem one time. On another install it didn't.
sudo apt-get remove unity-control-center
Display
When I connect a monitor to my laptop on HDMI automatically a 3rd VGA display is found.
- xrandr --listactivemonitors
- Show all active monitors
- xrandr --output VGA-1-2 --off
- Turn off the VGA display. The name may differ on other configurations.
Add applications
To add an application to the 'Open with' list edit /usr/share/applications/<newapp>.desktop.
For opening jupyter notebooks I added jupyter.desktop that looks like below. I don't think everything is needed but it works.
[Desktop Entry] Type=Application Version=1.0 Name=Jupyter GenericName=Jupyter notebook Comment=Prototyping and documentation Exec=jupyter notebook %F Icon=jupyter Terminal=false Categories=GTK;Development;IDE; MimeType=text/plain;text/x-python; StartupNotify=true Keywords=Python;Editor;
Autostart applications
To automatically start an application when a user logs in put a link to /usr/share/applications/<newapp>.desktop or a new <newapp>.desktop in ~/.config/autostart
