Hi, I have an issue with the X server, evdev library more precisely. When a mouse (or a compatible device) is detected by the X server, the server does actually detect an event device (/dev/input/eventN) and a mouse device (/dev/input/mouseN). On the event device detection is successful, but the mouse detection fails because of the EVIOCGNAME ioctl failing. As a result the evdev module gets unloaded. Depending on which detection happens in first place the mouse will/won't work : - if the mouse device gets detected first the mouse will work - if the mouse device gets detected after the event device the evdev module will get unloaded and the mouse won't work
See below the /var/log/Xorg.0.log : [ 18.672] (II) config/udev: Adding input device Logitech USB-PS/2 Optical Mouse (/dev/input/event2) [ 18.672] (**) Logitech USB-PS/2 Optical Mouse: Applying InputClass "default" [ 18.672] (II) LoadModule: "evdev" [ 18.675] (II) Loading /usr/lib/xorg/modules/input/evdev_drv.so [ 18.676] (II) Module evdev: vendor="X.Org Foundation" [ 18.677] compiled for 1.9.0, module version = 2.4.99 [ 18.677] Module class: X.Org XInput Driver [ 18.677] ABI class: X.Org XInput driver, version 11.0 [ 18.678] (**) Logitech USB-PS/2 Optical Mouse: always reports core events [ 18.678] (**) Logitech USB-PS/2 Optical Mouse: Device: "/dev/input/event2" [ 18.683] (--) Logitech USB-PS/2 Optical Mouse: Found 3 mouse buttons [ 18.683] (--) Logitech USB-PS/2 Optical Mouse: Found scroll wheel(s) [ 18.683] (--) Logitech USB-PS/2 Optical Mouse: Found relative axes [ 18.683] (--) Logitech USB-PS/2 Optical Mouse: Found x and y relative axes [ 18.684] (II) Logitech USB-PS/2 Optical Mouse: Configuring as mouse [ 18.684] (**) Logitech USB-PS/2 Optical Mouse: YAxisMapping: buttons 4 and 5 [ 18.684] (**) Logitech USB-PS/2 Optical Mouse: EmulateWheelButton: 4, EmulateWheelInertia: 10, EmulateWheelTimeo0 [ 18.684] (II) XINPUT: Adding extended input device "Logitech USB-PS/2 Optical Mouse" (type: MOUSE) [ 18.685] (**) Logitech USB-PS/2 Optical Mouse: (accel) keeping acceleration scheme 1 [ 18.685] (**) Logitech USB-PS/2 Optical Mouse: (accel) acceleration profile 0 [ 18.685] (**) Logitech USB-PS/2 Optical Mouse: (accel) acceleration factor: 2.000 [ 18.685] (**) Logitech USB-PS/2 Optical Mouse: (accel) acceleration threshold: 4 [ 18.685] (II) Logitech USB-PS/2 Optical Mouse: initialized for relative axes.

How can this be fixed? Is it an issue with the evdev kernel driver or an issue with X server/evdev extension?
