Tower is now upgraded to "xserver-xorg-hwe-16.04".
Prior to doing this upgrade today:
A. Config @ beginning [as of yesterday's work]: Intel gpu & Nouveau driver.
B. Today's discovery: 2 out of 2 attempts to Suspend-Resume failed. Post-Resume, x-session was frozen. I presume this indicates incompatibility of Intel gpu with Nouveau driver, as Rocky intimated.
So i did:
1. TTY attempt "sudo prime-select nvidia" failed; given neither Nvidia gpu nor driver was active, this command was unrecognised.
2. Rebooted & logged in, then in Maui Settings - Driver Manager, changed back from Nouveau to latest Nvidia driver
4. Rebooted
5. Now active gpu is again Nvidia, with Nvidia driver loaded too.
The Nouveau-blacklisting etc for now is deliberately held-over til [/if there is] the next freeze.
Thanks Rocky.
