Comment 0 for bug 538474

Running Lucid in virtualbox-ose on a macbook pro 5,3 host. Keyboard model is set to MacBook.MacBook Pro. Tried to make the Option_R/Alt_R key function as Alt_R instead of ISO_Level3_Shift in System>Preferences>Keyboard>Layouts>Options. It did not take, and the following pop-up appeared:

Error activating XKB configuration.
It can happen under various circumstances:
- a bug in libxklavier library
- a bug in X server (xkbcomp, xmodmap utilities)
- X server with incompatible libxkbfile implementation

X server version data:
The X.Org Foundation
10705000

If you report this situation as a bug, please include:
- The result of xprop -root | grep XKB
- The result of gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd

$ xprop -root | grep XKB
_XKB_RULES_NAMES_BACKUP(STRING) = "evdev", "pc105", "us", "mac", ""
_XKB_RULES_NAMES(STRING) = "evdev", "pc105", "us", "mac", ""

$ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd
