Description Vincent Lefevre 2013-11-02 17:06:25 UTC
I have personal XKB settings. From my .initrc file:

  xkbcomp -w0 -I$HOME/.xkb -R$HOME/.xkb keymap/custom $DISPLAY

Most often they are lost after suspend/resume on my DELL Latitude E6400 laptop. Moreover when I plug-in a USB keyboard, these settings are not taken into account for this keyboard (the laptop keyboard remains unaffected).

After resume, I can run

  xkbcomp -w0 -I$HOME/.xkb -R$HOME/.xkb keymap/custom $DISPLAY

again without quitting the X session, but some running X clients do not take all new settings into account (problem with modifier keys?).

I originally reported the bug on:

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=633849

where you can find additional details.

With my Dell laptop this bug occurred after resume in more than 90% of cases, I have not found a rule for when it occurs and when not.

With my new Lenovo laptop, after a few hundred suspend/resume, this bug has never occurred to me.

So I suppose this bug is caused by a race condition on some computers only.

I see exactly the same problem. Starting out with a laptop with a built-in keyboard and set the "ctrl:nocaps" option in order to make my Caps Lock key an additional Control, like so:

$ setxkbmap -option ctrl:nocaps
$ setxkbmap -query
rules:      evdev
model:      pc105
layout:     no
options:    ctrl:nocaps
$ 

At this point, the Caps Lock key on the built-in keyboard does indeed act as an additional Control key. All is well. However, the moment I plug in an USB keyboard, the options line vanish:

$ setxkbmap -query
rules:      evdev
model:      pc105
layout:     no
$ 

The Caps Lock key on the built-in keyboard continues to function as an additional Control, but the Caps Lock key on the USB keyboard is not. It is just acting as a regular Caps Lock key.

I have to re-issue the "setxkbmap -option ctrl:nocaps" in order for the Caps Lock key on the USB keyboard to become an additional Control. However, if I disconnect and reconnect the USB keyboard, the ctrl:nocaps option is again lost, even though the USB keyboard keeps its old device id (as shown by "xinput list").

The same effect can be seen with a regular layout. If I do, e.g., "setxkbmap us" to get an American layout, it will only apply to keyboard(s) that are connected at that time - future keyboards being plugged in (or disconnected and then reconnected) will default to Norwegian layout.

I have similar problem, but related to keyboard layout, not a custom XKB settings. I found the only way to set defaults for a new input device at runtime (without restarting Xorg to pick up modified xorg.conf) is to set xkb* udev properties on a device (for example by adding new rule and reloading udev).
