Bug 236510

Is there a good way to detect this?  If so, we could fall back to the lowres
(640x480) mode.

It's not as pretty, but it works

Well, the X server knows the dimensions -- xdpyinfo can tell you, for example.
Is it possible for the graphical installer to query the X server when it starts
up, and go into low-res mode if the screen is smaller than 800x600?

If we need to do it in advance with fbdev, then we could -- we can use the
FBIOGET_VSCREENINFO ioctl on /dev/fb0...

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
#include <linux/fb.h>
#include <sys/ioctl.h>

int main(void)
{
	int ret, fd = open("/dev/fb0", O_RDONLY);
	struct fb_var_screeninfo var;

	if (fd < 0)
		return 1;

	ret = ioctl(fd, FBIOGET_VSCREENINFO, &var);
	if (ret)
		return 1;

	printf("Screen is %d*%d\n", var.xres, var.yres);
}

Okay, hopefully put something in place that'll handle this.  Will be in
tomorrow's rawhide

Doesn't seem to be having the desired effect.

The change I see in CVS seems to be setting up the X server to do 640x480 mode
-- something it was doing already. Perhaps I'm missing something, but I don't
see how that change is intended to affect the graphical interface of the installer.

That seems to be handled entirely separately in gui.py, but also from code
inspection looks like it should correctly fall back to 640x480 if the width is
less than 800....

        if gtk.gdk.screen_width() >= 800:
            self.runres = "800x600"
        else:
            self.runres = "640x480"

I've just seen it correctly fall back to 640x480 mode on a different machine,
where X happens to come up at 640x480. I wonder if the fbdev X server isn't
reporting the correct resolution. Will investigate further... I think there
should also be a PS3 in Jesse's cube by now too.

Ah. It seems the '480i' mode only has 576x384 _visible_ pixels. Perhaps we
should just fall back to text or vnc installation?

We _can_ actually change video mode on the PS3, but I don't think we want the
installer to be involved there; we'll let them set it from the bootloader, and
the kernel can inherit that setting. It depends on what video hardware they have
hooked up, of course. We'll only be using 480i if they have an SD-only NTSC
television, but I think we have to use that as our default mode. 

Now I'm confused though -- the 'full-screen' SD video modes on the PS3 are 480
lines for NTSC and 576 lines for PAL, while the 'normal' modes are 384 and 460
lines respectively. But aren't 480 and 576 _already_ cut down from the full
video signal of 525/625 lines for NTSC/PAL, to match the viewable area? I wonder
why we're losing _more_ of the picture for the PS3?
