Prt sc Disabling trackpad

[Shreyasv2108]

hi
Is there a way to remap Prt sc so that it does not disable the trackpad?
I am running the latest version of Voodoo PS2 Controller kext

Thanks

If you're using my VoodooPS2Controller.kext, you can remap any key via ACPI.
In my u430 repo, I remapped PrtSc to invoke a function key, which I then mapped in SysPrefs->Keyboard->Shortcuts to one of the screen capture functions.
See here:
https://github.com/RehabMan/Lenovo-U430-Touch-DSDT-Patch

custom code is in SSDT-HACK.dsl.

how can I remap it to screen capture?

Yes.
As I wrote in my reply, that's exactly what I did on the u430 (the u430 has a separate key for trackpad disable/enable).

so do I have to copy that ssdt and paste it in my acpi patched directory?

No.
You need to create your own.
That SSDT is all the code for all patching of the u430.
The part you need (for remapping the PtrSc) is only a very small portion of it.

For example:

// This sample shows how to remap the PrtSc key to F13
// F13, for example, could then be mapped to one of the image capture functions
// via SysPrefs->Keyboard->Shortcuts

DefinitionBlock ("", "SSDT", 2, "hack", "ps2", 0)
{
    External(_SB.PCI0.LPCB.PS2K, DeviceObj)
    Scope (_SB.PCI0.LPCB.PS2K)
    {
        // overrides for VoodooPS2 configuration...
        Name(RMCF, Package()
        {
            "Custom PS2 Map", Package()
            {
                Package(){},
                "e037=64", // PrtSc=F13
            },
        })
    }
}
//EOF

Obtain an audio codec dump from Linux.
