status as of yesterday evening:

nomodeswitch had no effect at all. Not even reboot works (I forgot to 
mention
it earlier, clicking on reboot has the same freezing effect as clicking 
shutdown)

In terms of kernel parameters, the least bad so far is acpi=off. With 
this, the
shutdown process at least starts (see earlier email about "white dots 
turning red")

Installing older/newer kernels: I'm trying to avoid that for now,

I have followed the final suggestion here:

https://bugs.launchpad.net/ubuntu/+source/unity-settings-daemon/+bug/1546641

so I updated kernel and other packages with that extra repository,
but in and by itself (ie with no extra kernel parameters) it makes NO 
difference.

This was yesterday. Today:

updated as above +

nomodeswitch => no difference
acpi=off     => no difference, plus something that did not happen with 
this
                 option before kernel update: makes desktop unusable,
                 screws compiz apparently. Sometimes, I can open a 
terminal in
                 unity, but not even type into it. Others, video playback
                 doesn't work..
noacpi       => no difference


I am quite close to give up on Ubuntu and just try another distro. No 
recrimination,
critics, none of the sort. It's just lack of time: I leave for a 
business trip on Monday,
and by then  I DO need a working linux laptop to come with me. But I'd 
really like
to try Ubuntu. Any other suggestion is still very appreciated, and I may 
try it when
I come back.

Thanks,
Marco
