Re: PS3 controller (SIXAXIS) never gets into "IdleTimeout"

Hello,

Hi Manuel,

I want to use my PS3 controller on my Linux system. This, so far, seems 
to work pretty well, but if I forget to turn off the controller when 
leaving my PC, then the battery keeps discharging until it is finally empty.

There is a setting "IdleTimeout" in "input.conf", but at least for me 
this doesn't work for the PS3 controller.

I think the reason is, that the controller keeps sending information 
even if it is placed on my desk and noone is touching it. If I run 
"evtest" on the event device, created for the controller, then I get 
something like this (only short snippet):

Event: time 1453228629.616457, -------------- SYN_REPORT ------------
Event: time 1453228629.651514, type 3 (EV_ABS), code 1 (ABS_Y), value 124
Event: time 1453228629.651514, type 3 (EV_ABS), code 61 (ABS_MT_TOOL_Y), 
value 491
Event: time 1453228629.651514, -------------- SYN_REPORT ------------

Seems like the controller keeps sending axis information even if the 
axis aren't touched at all.

IIRC this is because the controller has a lot of axes and they end up in
the multi touch range (ABS_MT_*) which apparently sends event
continuously.

I remember I did some experiments about remapping the axes to a more
meaningful setup and there were some improvements but that work
depended on some experimental changes to the linux input layer from
David Herrmann (the ABS2 proposal) and I do not know if the latter ever
reached mainline. This is a linux-input topic BTW.

Is there any chance to add some handling into bluez to get the 
controller disabled, even if it keeps sending information in "idle state"?

If you disconnect the device from bluez (either from an applet or from
command line) the sixaxis should turn off.

JFYI a possible hardware way is to keep pushed the PS button for some
seconds, this also should turn the sixaxis off.

Ciao ciao,
