The topic came up, a user was having issue with his laptop restarting instead of powering down. I recommended they try the command; shutdown -P now. LXLE and other LX distributions use; lxsession-logout and lxde-logout. These logout shortcuts can be found in /usr/share/applications as shown here.
One can see by execution they will open the logout options menu. If you replaced the command within as Root, to read; shutdown -P now - the PC would immediately power off. On the other hand, if you wanted the PC just to reboot by default; shutdown -r now would perform an immediate reboot without question.
I then thought of the fastest way to do both these commands, other than composing a hotkey. I right clicked my desktop and selected the properties, advanced tab, and check marked, "show menus provided by window managers" options.
Since this runs OpenBox, I edited the menu.xml located in ~/.config/openbox In place of the Restart and Exit options I replaced them with these lines; <item label="Reboot Now"> <action name="Execute"><execute>shutdown -r now</execute></action> </item> <separator /> <item label="Power Down"> <action name="Execute"><execute>shutdown -P now</execute></action> </item> Saved the menu file, right clicked the desktop, and Reconfigure. Now when I right click on the desktop, I get my new options for a speedy exit. Using this is fast enough, the browser asked me, if I wanted to restore my last session.
