I am trying to get g550 to output to a TV, on first head...
from the doc. I think first head is the DVI output...
I enable matrox fb in kernel, so I have
-----------------------------------------
torus matroxset-0.4 # dmesg|grep fb
PCI: PCI BIOS revision 2.10 entry at 0xfb250, last bus=1
matroxfb: Matrox G550 detected
matroxfb: MTRR's turned on
matroxfb: 640x480x8bpp (virtual: 640x26208)
matroxfb: framebuffer at 0xD4000000, mapped to 0xc8880000, size 33554432
fb0: MATROX frame buffer device
matroxfb_crtc2: secondary head of fb0 was registered as fb1
------------------------------------------------
however, I have
--------------------
video=matrox:vesa:280,noblink
---------------------
in my grub....from matrox doc, this is supposed to be 1024x768x32
but (matroxfb: 640x480x8bpp (virtual: 640x26208)
after bootup, my TV starts to snow....so I suppose some signal was sent to head1
now I suppose I need to use matroxset to setup my fb and the
output...except I can't find any docs. on how to use matroset (the -m
option)....
so I did
---------------------
torus matroxset-0.4 # ./matroxset -f /dev/fb1 -m 0
torus matroxset-0.4 # ./matroxset -f /dev/fb0 -m 1
torus matroxset-0.4 # ./matroxset -f /dev/fb1 -m 2
-------------------------------------
from a file called normal from matroxset directory...
now I did
-------------------------
fbset -fb /dev/fb0 -xres 640 -yres 480
--------------------------
but still snowy....
anyone has any suggestion?
I want to use mplayer with -vo cvidix
thanks
chen
