How do you eliminate the power off dialog, or at least shorten the time interval? By default, it’s a 60-second wait. For a blind person, that’s a long time.
To bypass GNOME logout dialog you can change the user dconf key /org/gnome/gnome-session/logout-prompt to false:
For instance, you can use this command to do it (using regular user, not root):
dconf write /org/gnome/gnome-session/logout-prompt false
I don’t know if timer can be changed.

Hi Jon,
GNOME doesn’t currently allow shortening or disabling the 60-second power-off dialog.
For blind users, the most practical solution is to bypass the dialog entirely.
You can power off or reboot immediately using terminal commands, or bind them to keyboard shortcuts:
-
Power off immediately
systemctl poweroffor
shutdown now -
Reboot immediately
systemctl rebootor
shutdown -r now
These commands work instantly, do not show any confirmation dialog, and are much more accessible when used via the terminal or assigned to custom keyboard shortcuts.
This is currently the most accessible workaround for blind users on GNOME.
As far as I remember, you’re looking for solutions for a blind user (like myself).
In that case, I’d strongly recommend trying Accessible-Coconut.
It’s a Linux distribution specifically designed with very strong accessibility support out of the box, and many of these GNOME-related usability issues are already handled more gracefully.
It might be a much better experience overall for a blind user than stock GNOME on Ubuntu.
Actually, I use this all the time as part of my normal computer habits.
I think more users should be made aware of the power of systemctl.

I totally agree.
Even experienced users can gain a lot from exploring systemctl more deeply—it’s a very powerful tool once you get used to it.

I don’t have Gnome, but if you open dconf-editor, and search for “power”, you might see an option like the one listed below, but under the gnome tree:
If you click on that, you will get a window that looks something like the one below (for MATE in my case), where you can **change the option setting**
-
from “interractive”
-
to “shutdown”.
