Disabling suspend and hibernate in Linux

There is a line in /etc/gconf/schemas/gnome-power-manager.schemas that says:

"Allow Suspend and Hibernate in the menu"

A few lines above that, it defines "true" as the default.

This is somewhere around line 1308.

Kind regards,

If it's not a BIOS issue, it may be as simple as hitting Alt-F2, typing gconf-editor and then going to /apps/gnome-power-manager/general and unchecking can_hibernate. I've not tried this but, that should tell the whole gnome power management system that your machine isn't able to hibernate. If not, something around that area in gconf-editor might help you.

Press Alt+F2 and type in gconf-editor and press Enter. Navigate to /apps/gnome-power-manager/general There, uncheck can_hibernate and can_suspend Close the editor window..

In gconf-editor disable the keys by unchecking : /apps/gnome-power-manager/can_hibernate and /apps/gnome-power-manager/can_suspend

Right click on these keys and set as mandatory.

I had problems with a couple of my old machines resuming from suspend/hibernate. I couldn't seem to fix that so I just disabled the functions by editing /etc/default/acpi-support and commenting out the lines for ACPI_SLEEP and ACPI_HIBERNATE per the instructions in the file. After restart there are no more menus for either function.

And a followup:

In Hardy, this seems to have moved just slightly. The keys are now

/apps/gnome-power-manager/general/can_suspend /apps/gnome-power-manager/general/can_hibernate
