Xboxdrv returning back to normal settings when leaving Dosbox

retropieuser555

Hi all, so I've managed to get xboxdrv up and working so my 8bitdo controller acts as a mouse for Fallout. All good so far and the game plays like a dream which is great.

But for some reason I can't seem to get the controller to function again once I'm back in emulationstation. I was looking through some old topics and my understanding is you need to killall like I've done below, but I guess this is turning off all functions? How do I write this so when I come back to emulationstation the control function for there kicks back in?

#!/bin/bash
sudo killall > /dev/null 2>&1 xboxdrv
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--detach-kernel-driver \
        --mouse \
&
sudo /opt/retropie/emulators/dosbox/bin/dosbox -c "mount c /home/pi/RetroPie/roms/pc" -c "c:" -c "cd fallout1" -c "FALLOUT.EXE" -c "exit"
sudo killall > /dev/null xboxdrv

The script you posted should stop the xboxdrv from after returning from dosbox. But you don't want to run dosbox through sudo, so remove that (3rd command).

@mitu Thanks for the reply. I've adjusted the code now and removed the that 3rd sudo, but it's still not responsive upon return to emulationstation.

If I put the controller back into a different mode & then back into the xbox 360 mode, it runs again, but that's as I've kicked xboxdrv off and the controller is back to being Xbox 360 Wireless Receiver (XBOX) as opposed to Xbox Gamepad (userspace driver).

As I think xboxdrv kicks off at the boot, right? But oddly it's like the script won't run again once you've killed it.

#!/bin/bash
sudo killall > /dev/null 2>&1 xboxdrv
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--detach-kernel-driver \
        --mouse \
&
/opt/retropie/emulators/dosbox/bin/dosbox -c "mount c /home/pi/RetroPie/roms/pc" -c "c:" -c "cd fallout1" -c "FALLOUT.EXE" -c "exit"
sudo killall > /dev/null xboxdrv

Try executing the xboxdrv commands manually, from an SSH session, before and after starting the game. Leave the script to contain the dosbox command only and execute

# before starting a game
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv --detach-kernel-driver --mouse 

# start the game from EmulationStation, see if the driver works

# stop the driver
sudo killall xboxdrv

This way you'll see if any errors show up, maybe the way you start xboxdrv is not correct.

Hiya, so the first line is giving me an error at the end but I'm not sure what that means exactly?

Try to run 'rmmod xpad' and then xboxdrv again or start xboxdrv with the option --detach-kernel-driver.

I don't have xpad installed on my pi, do I need to install that as well?

This means another driver is managing the device and you need to unload the driver or - as the message suggests - add another option to the command --detach-kernel-driver.

@mitu But haven't I already got that command in the code above at the beginning? After the path to xboxdrv?
