Got it working!
Hooray!
Here’s how:
Call back Lenovo tech support. Bully my way through two or three phone calls until finding the support rep who tried to reach me a couple of days ago without a callback number, leaving only an email from “Ahmed”. After much persistence got a return call from Ahmed.
He guided me through the following steps, some of which I hadn’t known about.
sudo apt update
sudo apt upgrade
sudo apt install update-manager-core <-- didn't do initially
reboot
sudo apt dist-upgrade <-- didn't do initially
This brought me up to 22.04.5 LTS
tried
sudo do-release-upgrade
This failed as before.
Edited /etc/upgrade-manager/release_upgrades changing never to normal. Then
sudo do-release-upgrade again
This time success.
So Three cheers for Ahmed.
One and a half cheers for Lenovo. Points off for
- not doing this themselves
- not having a document that explaining the steps that needed to be done
- making it so difficult to find a support rep capable of helping.
And three cheers for Discourse for giving it their best shot!
As to the graphics card, are these the settings I want going forward?
