I have a new Logitech Laser cordless mouse with the mini-receiver, V450 Nano. Anyway, I find the right button (secondary click) doesn't work. Using xev i can see button 1 is left button, 2 is scroll wheel push, 4 and 5 are scroll wheel up and down and 6 and 7 are scroll tilt. Right button registers nothing.

Now, if I install mousetweaks and enable secondary click, I can make the right button work if I hold the left button down first and also if i hold and press the left button. These two actions/combination show up as button 3 in xev. Everything else works, including scroll wheel and horizontal scroll.

I've tried adding an xorg.conf file and playing around with that but without the button 3 action to start with, it seems a bit pointless.

Anyone know where to start with fixing this?

Its on a Fedora 10 clean install, the mouse is brand new.

uname -r: 2.6.27.15-170.2.24.fc10.i686

cat /proc/bus/input/devices gives me this:

I: Bus=0003 Vendor=046d Product=c526 Version=0111
N: Name="Logitech USB Receiver"
P: Phys=usb-0000:00:10.3-2/input0
S: Sysfs=/devices/pci0000:00/0000:00:10.3/usb5/5-2/5-2:1.0/input/input4

H: Handlers=mouse1 event4
B: EV=17
B: KEY=ffff0000 0 0 0 0 0 0 0 0
B: REL=143

in xorg.conf i have added this, although none of it seems to make a difference:

Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard" "Configured Mouse"
Option "AutoAddDevices" "off"
EndSection

Section "InputDevice"
Identifier "Configured Mouse"
Driver "evdev"
Option "CorePointer"
Option "Name" "Logitech USB Receiver"
Option "Device" "/dev/input/event4"
Option "Buttons" "9"
#Option "ZAxisMapping" "6 7"
#Option "ButtonMapping" "1 2 3 6 7"
#Option "Resolution" "800"
EndSection

I have one of those mice, it works fine "out of the box". [Though I do not use "scroll tilt"].
I suspect your mouse is broken.

Thanks for the reply. You are using this with Ubuntu or Fedora 10? I checked it with Ubuntu and some of the buttons don't work there either. No right button at all and the left only works intermittently. I will check it on a Windows machine later and see how that goes.

Update: the mouse was faulty. The supplier replaced it, finally, and everything works fine now.
