Q: Suspend isn't working anymore after upgrade to xubuntu 15.10

pprSuspend doesn't halt my old computer (DELL Precision T7400) since I updated to xubuntu 15.10. I have a black screen after suspending but the computer is still working (fan, led, ...) I suspect systemd to mess up with pm-suspend. I tried to suspend in different ways: pm-suspend xfce4-session...

ubuntu systemd xfce suspend xubuntu

How would I test/demonstrate that sudo -H sets $HOME to my own home directory? (vs /root)
sudo -H echo $HOME doesn't work because the shell expands $HOME before execution..

@Seth Put it in a script?
 
Seth
Seth
hmm, that might work.

Doesn't work here: sudo -H ./foo.sh
/root
 
Seth
Seth
yeah, that's what I'm finding out :)
I guess I misunderstood the manpage.

Faheem Mitha
That's actually working as intended, I think.
I mean, this might be default behavior.

ooh, looks like sudo -H env | grep HOME works.
@FaheemMitha yeah.
 
Gilles
Gilles
@Seth sudo -H sh -c 'echo $HOME' or sudo -H env | grep \^HOME
 
Seth
Seth
I completely misunderstood that section of the manpage apparently.
@Gilles thanks!

Gilles
@Seth it's the opposite: -H sets HOME to the target user's home directory

@Gilles It also appears to be the default. Though the man page does not say so.

@FaheemMitha depends on the compile-time configuration IIRC

@Gilles Well, I just meant the Debian version on jessie.
