+Subject: [PATCH xserver] xkb: after changing the keymap, force an indicator
+ update
+
+When NumLock is on and a new keymap is applied, the next modifier state change
+will turn off that LED (but leave the state enabled). The cause for this is a
+bit convoluted:
+* the SLI explicitState is copied from the current state in
+  ProcXkbGetKbdByName. Thus, if NumLock is on, that state is 0x2.
+* on the next modifier key press (e.g. Shift), XkbApplyState() calls into
+  XkbUpdateIndicators() -> XkbUpdateLedAutoState() to update SLIs (if any) for
+  the currently changed modifier. But it does so with a mask only for the
+  changed modifier (i.e. for Shift).
+* XkbUpdateLedAutoState() calculates the state based on this mask and
+  ends up with 0 because we don't have a Shift LED and we masked out the
+  others.
+* XkbUpdateLedAutoState() compares that state with the previous state (which
+  is still 0x2) and then proceeds to turn the LED off
+
+This doesn't happen in the normal case because either the mask encompasses all
+modifiers or the state matches of the masked-out modifiers matches the old
+state.
+
+Avoid this issue by forcing an SLI update after changing the keymap. This
+updates the sli->effectiveState and thus restores everything to happy working
+order.
