keyboard problem with UP & PrintScrn

keyboard problem with UP & PrintScrn

[Ed Tomlinson]

Hi,

I reciently switched to xorg 1.8 which uses udev for keyboard setup when using evdev.  My UP and Printscrn 
keys  did not work (all other keys work as expected).  xev does not show the keypress events for either of these 
keys.  Googling lead me to /lib/udev/keymap.  Running this with the -i option also fails to show the keypress events.  
There is also a constant stream of null events from keymap -i with the keypress / keyrelease events  coming out in 
this stream when a key is pressed.

In xorg.conf I have:

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "evdev"
        option      "Device" "/dev/input/event0"
        option      "CoreKeyboard"
        option      "XkbModel" "pc105"
        option      "XkbLayout" "ca"
        option      "XkbVariant" "fr"
        Option      "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection

and extracting from: udevadm info --export-db > /tmp/udev-db.txt"
I get:

The kernel is 2.6.33.2 and udev is 151-r1 (gentoo)

How do we go about debugging this one?

Thanks

Hi,

Just realized that udev is just showing a single entry for a key press.  Unless the constant stream events
is not normal please ignore this.

Thanks
Ed
