Recently our Puppy does not showdown, power off, restart or any of the other options at shutdown.
Would anyone please show us how to fix the issue?

What happens when you hit the LeftCtrl+LeftAlt+backspace key? Or Hit LeftCtrl+LeftAlt+delete keys?

The scripts to leave X are "wmexit" , "wmreboot" , "wmpoweroff" and "restartwm" . "which" command shows the location of executables .

Take a look into /tmp/xerrs.log for error messages .

Example: Open terminal and type in and it will show the location of that file.

What version of Puppy Linux also 5.? (Wary,Lupu,etc...). Is your install a frugal or full install?

When I hit the the LeftCtrl+LeftAlt+backspace key im taken to a black window where typing is available, I typed the scripts as : "wich wmreboot"
and the message follows back as: " -sh: wich: command not found"
The other scripts went typed after "wich" but found no command respectively.

This is version 5.1.2 a full install.

All that does is log you out of x. Just wanted to make sure that worked first. to get back to a desktop in that window you type

The which command is done using urxvt terminal while in Desktop mode by the way.

Typo error. Should be which instead of wich.

When I hit the power off button and the LeftCtrl+LeftAlt+backspace keys that works to shut down puppy and saves the session.

After typing "which wmreboot" the message follows back as "/usr/bin/wmreboot" and "wmexit" , "wmpoweroff" and "restartwm" also returned with prefix "/usr/bin/".

Where is urxvt terminal while in Desktop mode?

console icon on Desktop.

I don't run Wary (barrys kaulers release). It looks like you have all the scripts for wmexit, wmpoweroff, and restartwm in /usr/bin. I would next go into /usr/bin using rox file manager.
Find those files. Make sure they are executable via permissions or properties.

Then try shutdown again from Menu button. Next question. When you did your full install. When requested at shutdown. Did you make a save file? On full installs. The answer should have been no. On Frugal installs. The correct answer is yes and save to a file.

Our Warry puppy seems to work in order since I typed the "which" and shutdown commands on the black screen.
After that I also went to Rox File Manager and checked the respective permissions as you instructed.

This full install has been saved onto the hard drive from the start, the file save is automatic at shutdown.
Thank you so much!
