Hello,

At the moment, some XFree86-drivers force synchronization with the vertical retrace of the CRT whenever AdjustFrame is called,
whereas some drivers do not.

I think that a uniform behaviour would be favorable.

Tests have shown that the modifications necessary are trivial
and that the modified drivers work properly and reliably.
(Different people I know already tested that.)

I asked Alan Hourihane about his opinion. He suggested some
open discussion within the context of this mailing-list.

So what is your opinion?

Yes, it would be nice. AdjustFrame takes *flag* parameter so driver can
be informed whether the waiting needed. When driver just ignore *flags*
and dont wait - this can be explained somehow, but when driver ("mga" is
a good example) makes busy wait every AdjustFrame call... this is bad
bad thing as I think.
