Package: xfce4-screensaver
Version: 0.1.3-2
Severity: normal

I left home for the weekend, just ssh-ed in and I see:
  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
 2375 root      20   0  823412 223376 169752 R  96.3   2.7   1946:54 Xorg
24967 kilobyte  20   0   31540   5736   4496 R  34.9   0.1   1:26.92 zoom
24966 kilobyte  20   0   31144   5188   4320 S  28.2   0.1   1:11.75 zoom

The screen has been locked for nearly a day, thus it's obviously off (which
I can't verify).  For further information, I left this bug report
half-written for while; the screensaver has in the meantime rolled over to
something else that takes just 20% X + 2*7% for screensavers proper, then to
euler3d at 27% X + 2*13%.  That's better than nearly two full cores as for
zoom, but the question is: why?

Once the monitor gets suspended/slept/powered off, there's completely no
point in drawing anything.  On the other hand, a computer with two cores
worth of activity for a prolonged time wastes a significant amount of
electricity, which is bad both for the environment and for users' wallets.

Thus: could you please stop spawning new "draw something" processes once
the saver has gone past the first (visual) stage?


Meow!
