Public bug reported:
Thunderbird in Ubuntu 20.04 LTS was just upgraded to 78.7.1.
Unfortunately, that version has a bug which renders Tasks unusable for
those of us who depend on recurring tasks. Completed tasks keep coming
back to life on restart of Thunderbird. This results in incessant

That would be g-s-d's power plugin. See gpm-common.c,
disable_builtin_screensaver() and
gsd_power_enable_screensaver_watchdog(). g-s-d's po
I've read through the portions of Xorg that are directly related to the
screensaver timeouts (dixSaveScreens() and friends) and it appears that
my suspicion is incorrect. I was unable to find any sort of built-in
default screensaver. Another dead end.
Then I remembered that the kernel has a buil

Title:
[regression] on login screen, monitor stay
My (completely unconfirmed) suspicion at this point is that the problem
lies in xorg-server. I'm guessing that xorg-server has a built-in
default screensaver of some sort that turns off the monitor. In 13.04,
this was working fine. In 13.10, it no longer is. I'm going to shift
my focus to xorg-
Through some script trickery, I was able to get g-s-d running in debug
mode. It appears from the debug output that in 13.04, g-s-d's power
plugin is *not* responsible for powering off the monitor when lightdm
/unity-greeter is up. The question is: Who is?
(Power is out here, probably for a week,

It appears that the power plugin is indeed running in both 13.04 and
13.10 as I am seeing logging from it in /var/log/lightdm/x-0-greeter.log
in both 13.04 and 13.10.

It turns out that in 13.04, display power-off (when lightdm is up) is
driven by the X screensaver timeouts. If I do this:
xset s 60 60
...in lightdm's display-setup-script, the screen powers off (in 13.04)
in one minute instead of the usual 10.
13.10 has the X screensaver timeouts set to 10 m
Thanks, Eugene. Your solution works for me as well.
To complete this workaround, I've added a script to handle turning off
the X dpms timeouts when the user logs in. Here are the three files
that I've created. First, the config file:
/etc/lightdm/lightdm.conf.d/50-dpms.conf
