Dr. A's Ubuntu Install Notes
These are general notes and not specific to a class, so tread lightly if you are one of my students.
Ubuntu 18.04 - 22.04
Ground zero problem: DHCP is not pulling an address. Edit /etc/netplan/[?].yaml
network:
ethernets:
eth0:
dhcp4: true
dhcp-identifier: mac <-- this is the thing you need to add/change
version: 2
Remote Desktop Fix
One of the first things I like to do with an Ubuntu machine inst install xrdp. Here are the steps I got from here. Of course you should update the server first!
$ apt install -y xrdp $ sudo sed -e 's/^new_cursors=true/new_cursors=false/g' -i /etc/xrdp/xrdp.ini $ sudo systemctl restart xrdp
Create the .xsessionrc in your home directory and have it contain:
GNOME_SHELL_SESSION_MODE=ubuntu
XDG_CURRENT_DESKTOP=ubuntu:GNOME
XDG_DATA_DIRS=${D}
XDG_CONFIG_DIRS=/etc/xdg/xdg-ubuntu:/etc/xdgI like to use gnome so the following fixes were also added in /etc/polkit-1/localauthority/50-local.d/xrdp-color-manager.pkla
[Networkmanager] Identity=unix-user:* Action=org.freedesktop.color-manager.create-device ResultAny=no ResultInactive=no ResultActive=yes
Then you need to restart polkit:
$ systemctl restart polkit
That should do it for connecting from Windows.
