[tde-users] Laptop installation

Dear TDE list I have used tde for some time now, but mainly on desktops. I standardise on Ubuntu 20.04 LTS version but unfortunately the desktop version comes bundled with a desktop that takes ugly to new levels and does not offer multiple desktops, which are very useful as I have an additional screen plugged into the HDMI port. So I start by installing the server version, then add the trinity repositories and install as directed. That's always worked on my desktops. The platform is a Dell 7737 laptop with 16GB memory - quite old but reliable, nice display, etc and I have replaced the drive with a 1TB SSD so it is a completely new box. There are 2 display controllers, VGA compatible Intel Haswell-ULT and a 3D controller nVidia GeForce GT 750M. Now the issues: 1) I have no wifi or ethernet tools. The machine is currently working 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? 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? 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? Puzzled. -- John Logsdon Quantex Research Ltd m:+447717758675/h:+441614454951
