Thanks Daniel,
1) I uninstalled xserver-xorg-video-intel. No change.
2) I noticed that. 18.04 and Debian works fine on same machine.
Using a recent installation of 20.04 desktop with updates but little to
no changes from stock:
5.4.0-42-generic WORKS FINE on /dev/sda1:
5.8.0-38-generic on /dev/sda1 boots to desktop, cursor OK, but 1st or
2nd user action immediately renders system unusable. Freezes, various
screen flashing, reboots or reverts to user login.
Verified the above multiple times.
What else can I do to help?
Thanks!
