1) I have no wifi or ethernet tools. The machine is

with the installation settings in /etc/netplan via the wired networking.
Thus, if I want to use it elsewhere I cannot select wireless network
without editing the installation file(s). Network settings just tells
me that the platform is not supported and offers quite an old list of
options. What is missing from my installation?
I am using the network manager and tdenetworkmanager, which is working fine
at 95%. I had only once an issue when I was in a hotel. and the issue was
related to the shorewall firewall that was obviously not dynamic enough to
respond to the hotels network
Here I would also check if I were member of the group netdev
2) There is no suspend or other power options. As I
use it as an
effective desktop that is permanently plugged in, this may not matter
but again, what can be missing?
Here I would check if I have the proper permissions for the group plugdev
see /etc/dbus-1/system.d/org.trinitydesktop.hardwarecontrol.conf
3) If I go to the power settings and try to change anything, the display
on the laptop goes bananas with for example the nice plain blue xterm
header turned into a rainbow, blotchy characters etc. Moving the
offending object to the external screen . I've seen this before and the
answer with an nVidia graphics card was to install the nVidia-418
drivers from the Ubuntu repository and block nouveau. Initially, with
nouveau, this happened which is why I installed the nVidia bundle but it
happens with that as well. Could this be a confusion between the two
display controllers because the extension screen is not affected, or the
missing power options?
I also had this bug on older Dell ... but I do not remember what was the
solution. I do not think it is confusion between the two controllers or
related to the power option. I remember it was something different, but can
not reach to the details.
