[Bug 966744] Re: Resume from suspend leaves me with black screen or a screen of the desktop before it suspended (though the mouse still moves/changes cursor)

 

Indeed, it does appear that compiz can be killed and metacity replaced
after some wiggling around a TTY once it hits. I am currently running
metacity's window decorator. And, indeed, running compiz --replace once
I can get the desktop usable again will bring it back to a 'frozen'
state with the cursor changing as necessary for window management again.
It also spews out error messages that says something like "invalid
configuration, this should never happen, you should probably raise a bug
report about it".

After an additional metacity --replace, however, I was able to smudge
compiz back in there, although I could not get Unity back up and running
(was complaining about unknown exit status of the other program).

As some people also had this issue with gnome shell, I feel that it may
be bad interaction between xorg and drivers for compositing (but what do
I know). I was getting invalid page flips from my dmesg when debugging
in the xorg bug report (the developer just kind of disappeared and
hasn't replied).

I don't mean to be a prude to the compiz devs (I know they're very busy)
But for the meantime I am going to bump up importance to 'critical' as
the bug has 'a severe impact on a large portion of Ubuntu users' and
'crashes the entire operating system'. They'll decide better than I once
they look at it, though (for all I know, it still isn't in compiz).

** Changed in: compiz (Ubuntu)
   Importance: High => Critical

** Also affects: compiz-core
   Importance: Undecided
       Status: New

** Changed in: compiz-core
       Status: New => Confirmed
