I think the thread starter's problem is that the screen goes dark. You can't do anything useful with scripts or aliases when your screen is blank, because you don't even know if your terminal window has focus while your are typing. If there actually is an open terminal window in the first place ...

That may be true. I assumed the lamp going out on a terminal would have little effect on keys pressed. If it went into some other fault then we can't guess.

I'd think about setting the power button to do a graceful shutdown if possible. Laptops may not have full support for acpi or apm to do this.

If the screen is blank, then best way to safely reboot is to use

Code:

Alt + SysRq + reisub

CTRL-ALT-DEL works even when not logged in. I use it to shutdown after logging off all users.

Magic-sysreq is meant for developers who hang their machines. It is very low level, and is not easy to use.

If magic-sysreq is compiled into the kernel (it is not on Slackware), then the appropriate key presses are (you cannot do this with one hand, and is difficult even with two hands):

Alt+SysReq+e : end all processes
Alt+SysReq+i : kill all processes
Alt+SysReq+s : sync
Alt+SysReq+u : unmount
Alt+SysReq+o : shutdown computer

you hit the point. this is the problem. i would benefit with / through a shortcut that resets the whole system.
probably the notebook does not support those WAYS OF rebooting.

but i will dig deeper into all the hints you and all the great supporters made.

thx alot for all you did!

I think the easiest thing would be to create a script to shut down the machine, something like "sudo shutdown -h now", after making the proper modifications to the sudoers file to allow you to run shutdown without a password.

Then you can use your desktop environment's tools to assign a specific keyboard combination to that script, something like ctrl+alt+s. If you can't find or don't like the DE's keyboard shortcut GUI, you can always use xbindkeys instead.

hello dear suidicaleggroll

many many thanks - that sounds terriffic. i love this idea.

well how to implemnent -

first thing; i write the script.
secondly: i put it to the machine
third i choose and assign a shortcut key-combination

that should be the was...

well question: is the script very difficult.

probably it goes over my head. For any and all help i would be very very happy and thankful!!!11
