Bug 701

Hi Denk, could you provide more info on the configuration, especially:

- Which ARM board are you using
- which kernel version 
- The xserver config file (/etc/X11/xorg.conf)

As mentioned above, I build for the "qemuarm" configuration, which is
generic enough for me to be used on several different boards,
including a QONG eval board (Freescale i.MX31 based, see
http://denx-cs.de/?q=QONG) and a TWISTER eval board (TI Sitara AM3517
based, see http://denx-cs.de/?q=TAM3517).

I'm using our own (basicly mainline) kernel on the Qong (2.6.36
based),and the vendor-provided kernel tree on the Twister (2.6.32
based).

For /etc/X11/xorg.conf I used both the unmodified version from the
poky build and with the following tuning for the twister board:

I believe this is due to the AutoAdd clause in the xorg.conf under ServerFlags, at least it caused similar behavior for me on the beagleboard:

With:
        Option          "AutoAddDevices" "True"

The keyboard would not work at all.

With:
        Option          "AutoAddDevices" "False"

The keyboard would work if plugged in prior to starting X or after restarting X. Do you observe the same behavior Wolfgang?

Sorry, but I did not understand what exactly you want me to test.
There is no  /etc/X11/xorg.conf  fine in my image (nor any xorg.conf
in the whole file system image).  Also, the string "AutoAddDevices"
does not appear in any file in /etc.

What exactly should I do?

This is a bit of a mess right now as I'm experimenting with replacing kdrive with xf86-lite. However, for your immediate question, try creating /etc/X11/xorg.conf and adding the following to it:

Section "ServerFlags"
        Option		"AutoAddDevices" "False"
EndSection

My suspicion is that xkeyboard-config is reading that - but that's just a hunch.

Denk, does  Darren's suggestion works for you?

can we lower the priority since the reporter does not response for quite long time.

Wolfgang, is this still an issue for you?

FWIW I have seen this same problem with a recent build from master on an atom-pc system. Using the suggested workaround fixes it assuming you have the keyboard plugged in at X startup; surely however we want users to be able to plug in a keyboard at any time?

This is certainly a more generic X configuration issue and not a Kernel issue. Recategorizing, it also needs a new owner.

As the sumbitter has not updated information in a number of months, I am closing this, it can be repoened if the issue re-appears.

Rather than just closing this bug on the assumption it is fixed, I would much rather someone actually tested this; it's not hard to test.
