Meaning of noun + がどうとかいってたが


I found the sentence: 「なんでなんだっけ…… 魔王の代替わりがどうとかいってたが……」

Context: the character is reading a newspaper that talks about an event that
occurred because of the replacement of the Demon King.

I can understand the main gist of the phrase after seeing it's translation,
but I can't understand the meaning of **がどうとかいってたが** , I searched a bit and it
seems to be something, could someone explain it to me?




[どう](https://dictionary.goo.ne.jp/word/%E3%81%A9%E3%81%86/#jn-154925) means
_(some)how_ and
[とか](https://dictionary.goo.ne.jp/word/%E3%81%A8%E3%81%8B/#jn-157481) makes
the statement more vague.

A bit roundabout way to understand is to consider

  * 魔王の代替わりが **関係するとか** 言っていた said the replacement of the Demon King was **related** **or something**

and the sentence in question does not even make explicit how the replacement
of the Demon King is relevant:

  * 魔王の代替わりが **どう** とか言っていた said the replacement of the Demon King was **X** or something

More practically Aがどうとか言っていた can be seen as a set phrase meaning _said
something about A_ or _said it had something to do with A_. Or as a variant of
Aとか何とか言っていた = _said A or something_ , _(The speaker vaguely remembers someone)
said A_.
