OK, I've managed to find a workaround: adding a second keyboard layout has the side-effect of enabling you to change the "Alt/Win key behaviour" preference.
I can also reproduce this on demand, at least on my machine. (perhaps multiple layouts is the trigger for this bug? I am sure I had briefly had more than one in the past.) Anyway, I added the Afghanistan layout as it was the default after clicking "Add...". After adding a second layout, you'll have silently activated another preference - a key shortcut to swap between layouts. In "Keyboard Layouts..." this is known as "Key(s) to change layout" and is set as "Both alt keys together" after adding a layout. This is actually the important setting for the workaround. Now, if you remove the second keyboard layout the extras "Key(s) to change layout" setting will stay active and you will still be able to change the "Alt/Win" setting to/from Default. Hurrah! Workaround found. However, if you then change the "Key(s) to change layout" preference back to it's default setting (no items selected, heading will no longer be bold) then the original "Alt/Win" preference bug will be back - somehow the preference will be changed back to the "Control is mapped to Alt keys, Alt is mapped to Win keys" setting. Some nice xprop debugging output: With the "Alt/Win" bug present: $ xprop -root | grep XKB _XKB_RULES_NAMES_BACKUP(STRING) = "evdev", "pc105", "gb", "", "altwin:ctrl_alt_win" _XKB_RULES_NAMES(STRING) = "evdev", "pc105", "gb", "", "altwin:ctrl_alt_win" With a second layout and "Alt/Win" set back to "Default": $ xprop -root | grep XKB _XKB_RULES_NAMES_BACKUP(STRING) = "evdev", "pc105", "gb", "", "altwin:ctrl_alt_win" _XKB_RULES_NAMES(STRING) = "evdev", "pc105", "gb,af", ",", "grp:alts_toggle" With the second layout removed and the "Key(s) to change layout" preference kept active: $ xprop -root | grep XKB _XKB_RULES_NAMES_BACKUP(STRING) = "evdev", "pc105", "gb", "", "altwin:ctrl_alt_win" _XKB_RULES_NAMES(STRING) = "evdev", "pc105", "gb", "", "grp:alts_toggle" With the "Key(s) to change layout" preference set back to its Default: $ xprop -root | grep XKB _XKB_RULES_NAMES_BACKUP(STRING) = "evdev", "pc105", "gb", "", "altwin:ctrl_alt_win" _XKB_RULES_NAMES(STRING) = "evdev", "pc105", "gb", "", "altwin:ctrl_alt_win" Any help? -- gnome-keyboard-properties : won't set back to defaults https://bugs.launchpad.net/bugs/431144 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
