I have installed ironhide using ppa [11.10 - 32 bit, Dell xps 15]. After rebooting I tried to disable nvidia gpu using the command "sudo ironhide-disablecard". I got message as "ERROR : no module for nvidia found at /proc/modules" and "nvidia card disabled successfully". Is it a normal behavior? Please note I tried disabling the card without trying to enable it. 

Thank You

Currently ironhide is no longer maintained. You should install Bumblebee instead using the bumblebee/stable ppa.

But to answer your question: "Disabling" the nvidia card in this way does nothing. By default the nvidia card is not used, only when using optirun <command>. The nvidia card cannot be disabled any more then to deprive it of it's drivers and run on intel only.

However there is a possible workaround I read, which is to reverse engineer the windows drivers to find the ACPI calls needed, then create a script for it yourself. Not recommended unless you are an expert on this.
