I've tried your stuff on my WinFast GeForce256 DDR (V10.19.2000) and
it worked swimmingly up to 1280x1024x8 which is plenty of dots on my
17" iiyama.  I'll try 1600x1200 on my sony 19" tomorrow (eek, later
today).

Excellent work!

On my ASUS V3400 TNT 1280x1024x8 works fine.
However, 1600x1200 seems to give the right 'picture', but the mouse
does not want to go out of the upper-left half (two-thirds?) of the
screen. I can move the mouse to the left off the 'picture'
(in the 'margin'). I did apply the changes suggested by Jim to make
the cursor behave 'properly' at the screen edges.

and you do have

static void
nvidiacurload(VGAscr* scr, Cursor* curs)
{
	...

	scr->offset = curs->offset;
	vgaxo(Crtx, 0x31, vgaxi(Crtx, 0x31) | 0x01);

	return;
}

right?

i'm totally confused by this. when the cursor is visible on the screen,
does the menu pop up underneath it or offset somewhere, i.e. is the cursor
position correct but it just won't move beyond a certain limit? can you
actually make the cursor disappear off the screen on the left or top?
just to make sure, here's the cursor move routine i have:


static int
nvidiacurmove(VGAscr* scr, Point p)
{
	ulong*	cursorpos;

	if(scr->io == 0)
		return 1;

	cursorpos = KADDR(scr->io + hwCurPos);
	*cursorpos = ((p.y+scr->offset.y)<<16)|((p.x+scr->offset.x) & 0xFFFF);

	return 0;
}

I'm sure I rebooted using a 1600x1200 vgasize in the selected section
of plan9.ini .
In case it matters: I copied the monitor info from linux xvidtune.
Is there any debugging output that I could provide that would help
to diagnose this?
(running at 1280x1024x8 is already _much_ better than not running at all,
 so not running at 1600x1200 is not much of a problem at all,
 apart from the curious minds who want to know why it doesn't work)

It works fine for me. Are you sure you hadn't run it at some other
resolution first then upped it to 1600x1200 without rebooting?
