[Linux-fbdev-devel] Fixed-frequency monitor, and G45 second screen

[Carlo E. P. <fl...@fl...>]

Hi all. A few days ago, I asked for info regarding the configuration
to use for a TV-standard fixed-frequency monitor. Well,today at last I
got the monitor, and I verified that the numbers that we exchanged
work Ok. I eventually used C code to set the framebuffer. This is how
I set an instance of struct fb_var_screeninfo:

    fvs.xres=fvs.xres_virtual=736;
    fvs.yres=fvs.yres_virtual=576;
    fvs.xoffset=fvs.yoffset=0;
    fvs.bits_per_pixel=16;
    fvs.height=fvs.width=-1;
    fvs.accel_flags=0;
    fvs.pixclock=62500;
    fvs.left_margin=144;
    fvs.right_margin=64;
    fvs.upper_margin=34;
    fvs.lower_margin=10;
    fvs.hsync_len=80;
    fvs.vsync_len=5;
    fvs.vmode=FB_VMODE_INTERLACED;

and I have a good image - exactly what I needed. 
I have one problem, though... I would like to use both screens of a
Matrox G450 with two independent framebuffers. Well, the first (main)
screen is set correctly, but it seems that the second one does not
accept to go interlaced. Is this something well-known? Am I forgetting
something? 

Some help is (as usual) highly appreciated...

Carlo
