Logitech LX7 Mouse and Xorg

by webmaster on January 25th, 2008

The Logitech LX7 is a cordless mouse. I've been using it for about 4 months and rather enjoy it. It is recoginized immediately when plugged in (I use with Fedora Core 6, tested with Fedora Core 7), but needs a little tweaking as the default pointer movement is a little fast and you need to get the extra buttons recognized.

My xorg.conf section for the LX7, including commented out options I decided not to use:

Section "InputDevice"
    Identifier  "lx7"
    Driver      "evdev"
    Option      "CorePointer"
    #Option      "Device"      "/dev/input/event3"
    Option      "Name" "Logitech USB RECEIVER"
    Option      "Vendor" "Logitech"
    #Option      "Dev Phys"    "usb-0000:00:1d.1-2/input0"
    Option      "Buttons"     "9"
    Option      "ZAxisMapping" "6 7 8 9"
    #Option      "ButtonMapping" "1 2 3 8 9"
    Option      "Emulate3Buttons" "0"
    Option      "Resolution" "1200"
EndSection

Back and forward in Firefox works using the tilt wheel, but opposite of what you'd expect - tilt-right goes back and tilt-left goes forward. Middle click works fine, but occasionally my finger is at an angle and the tilt wheel winds up being triggered. I haven't gotten the two buttons behind the scroll wheel to work, but I've not really had time to play with it. I think I recall that events register for them, but I've not setup any actions yet.

Some other configurations you'll find wind up using 'xset' to slow the pointer speed. I do not.
