Bug 114960 – gnome-settings-daemon grabs the keyboard if an unknown key is present in the gconf database

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Philippe Troin 2005-12-09 00:29:48 UTC]

How to reproduce:

As a test user:

  gconftool-1 -t string -s /apps/gnome_settings_daemon/keybindings/www Help

(this assumes that your keyboard has no Help key)

Logout from your gnome session if you were logged in, and log back in.
Open a window and try typing.  It won't work.

---

How this can happen in real life?

 1. Machine A and B share home directories.
 2. Machine A has an "Internet" keyboard, B has a standard 104-key keyboard.
 3. Login on A, go to Desktop->Preferences->Keybindings
 4. Set a multimedia key.
 5. Now login on B. You now have a keysym which is defined and known to XFree,
but which has no keycode.  The bug then happens.

I've traced it to gnome-settings-daemon call XGrabKey with a 0 keycode.

Patch to gnome-settings-daemon

This patch prevents calling XGrabKey with zero keycodes.
