> Those codes are from gnome-power-manager program, it will judge the xevent->type, and when it works normally, the xevent->type will be equal with event_base + XSyncAlarmNotify(it is defined as 1), but sometimes the program will become abnormal , then after print the value of xevent->type we found that it will be "event_base + 2" but not "event_base + 1" at this situation.

Sounds like you're receiving a different event then; if you know what
that event is, then great, else just ignore it in your handler, I guess.

(In other words, if the event type isn't XSyncAlarmNotify, then it's not
an XSyncAlarmNotify event.)
