If you run 

watch -n 0.1 cat /proc/interrupts

does one of them increase reliably when you hit the key?

When running "watch -n 0,1 cat /proc/interrupts" (watch -n 0.1 errors out, maybe because of German environment???), the following row increases after each press:

  9:          5          0          0          0   IO-APIC-fasteoi   acpi


Others increase more quickly, but they are iwlwifi, i915, "Local timer interrupts" and "Rescheduling interrupts" which are out of interest, right?

Best regards,
Peter

Ok, so it's definitely being handled by ACPI somehow - probably via WMI, 
but unsure. Rez, any chance you can look at the original message and let 
us know if this is expected to work with the current driver?

Hi Matthew,

this topic is still valid. Could you help me debugging the hotkeys?

There're two issues:
1. The "Dell support center" hotkey generates keycode 0xEE, but this is done forever. That means that I don't see a release event.
2. The "Dell instant launch manager" hotkey doesn't generate anything.

Thanks a lot in advance,
Peter

Hi again,

I found a solution for the 1st issue. It needs a udev quirk to force_release. Please find attached a patch against current udev in Ubuntu 12.04.

For the 2nd issue, I still can't find a way to generate a keycode.

Thanks for your help!
Best regards,
Peter

Re: Dell Vostro V131: special hotkey not working

Hi again,

can anyone please help me debugging this issue? I'd like to get special key working. The "Dell instant launch manager" hotkey still doesn't generate anything.

I'm running Ubuntu 14.04 right now (kernel 3.13).

Thanks a lot in advance,
Peter
