Gave Up - Sticking with 20.04

A few years ago I figured out how to get Ubuntu-Mate 20.04 LTS to run on my Toshiba Portege-Z935. All it took was adding "nomodeset" in /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

and running

sudo update-grub

Worked like a champ - touchpad, audio, video, bluetooth, dual-WiFi, and the display (1366x768).

Comes the "Upgrade to 22.04.1?" and I thought OK, more goodness.

I tried the upgrade, and tried a clean install - both run fine in recovery mode, but for the life of me, I couldn't get past the lightDM fail even with the GRUB nomodeset "fix".
(sudo systemctl disable gpu-manager.service got me past the GPU manager fail.)

This laptop has Intel HD Graphics 4000 chip which works great in recovery mode but apparently confuses the latest GPU/WindowManager startup.

I'm done. Re-installed 20.04 with latest 20.04 package updates and I'm back where I started - HAPPY with Ubuntu-Mate
