Re: [PATCH] drm/mgag200: Increase bandwidth for G200se A rev1

Thomas, Jocelyn,

I just thought I'd let you know that it occurred to me that, now I
understood the workings of the mgag200 module better, I might be
able to get an even higher screen resolution than before.

So I relaxed the limits of this chip that returns unique_rev_id=1 to be
those that would have applied if it had had unique_rev_id=3, and set a
/etc/X11/xorg.conf.d/20-screen.conf file to contain the stuff below, and
used Settings->Display to pick 1920x1080 mode - and sure enough I get
perfect 1920x1080@60Hz screen resolution.

Interesting. Thomas, I owe you thanks for introducing the bug/feature we
have been discussing which has eventually led to my realising a big
improvement in my display. Also to all those who support open-source
software, without which a user would not be able to taylor his system to
match what he needs so well.

With best wishes,
Roger.
