I have recently installed Xubuntu 13.10 on my Vaio vpcea making me a Linux beginner. The problem is that laptop's power button is right on the edge of the bezel making it far too easy to press accidentally, in my opinion a design fault by Sony.
At present, when I press the power button it shuts down strait away and as you can imagine, when I'm accidentally pressing it all the time it gets very annoying! So I planned to change it to ask what I would like to do when I press it or at least ask if I'm sure.
So I went through the xfce GUI options "Settings Manager" - "Power Manager" to the field "When power button is pressed", but it was already set to "Ask". So I did some digging and found a thread telling me to navigate to
/etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-power-manager.xml where it said to find
power-button-action and check that
value="3". It already did.
So I looked some more and found this thread which focuses on acpi scripts. I tried solution 1 & 2 using sudoedit to change the files accordingly (I have made executable bash shell scripts already so I think I followed them correctly), but still no difference.
I also found this thread which instructed me to edit
/etc/systemd/logind.conf so that
HandlePowerKey=ignore. Still no luck.
I even tried my own approach to completely disable
/etc/acpi/powerbtn.sh by renaming it
powerbtn.sh.bak hoping for at least no response from the power button... and I have done many reboots in between... but still it shuts down!
I have also read that some people have the file
/etc/acpi/events/power_button, but I do not.
So does anyone have any other ideas? What else could be executing the shutdown sequence Is there something I'm missing?
I haven't undone any of these actions so every one of the above files is currently edited on my computer, with the exception that "Solution 2" automatically undone "Solution 1" above.
