Re: v4 x screen size and flicker
I have a G200 and NEC XV17. It works quite well, but I used the windows
settings to guide my X settings.
I see the mga_h1 error too, though no ill effects (unless this is
responsible for overlay mode not working). I filed a bug about it (87504)
which was reported upstream.
Probably the new install wiped away your old settings, so it's now picking
the first listed choice, or something like that. Try editing your
configuration file, comparing with your old one if possible.

Looks like X thinks your monitor isn't fast enough. You can set the
monitor info in /etc/X11/XF86Config. You'll have to find out if your
monitor will support higher ranges. For instance, my 17" monitor
Identifier "Generic Monitor"
Notice the upper end of the ranges are substantially higher. So with
same video card, but different monitor settings, I can get up to:
1600x1200@75Hz (which is way too high [small] for my tastes). If it
supported higher ranges before, it will support them again.
Note: I don't know what that mga_hal is about (maybe for a different
