hi, 

for the last days i have been trying to get the following setup to work: 

Nvidia Geforce card in AGP-Slot: 

01:00.0 VGA compatible controller: nVidia Corporation: Unknown device 0312 
(rev a1) (prog-if 00 [VGA])
      Subsystem: CardExpert Technology: Unknown device 0604
      Flags: bus master, 66Mhz, medium devsel, latency 248, IRQ 16
      Memory at d7000000 (32-bit, non-prefetchable) [size=16M]
      Memory at c0000000 (32-bit, prefetchable) [size=256M]
      Expansion ROM at <unassigned> [disabled] [size=128K]
      Capabilities: [60] Power Management version 2
      Capabilities: [44] AGP version 3.0 

and Matrox G450 PCI, 32MB, dualhead, 1x DVI, 1x VGA, tv-out plug attached to 
vga: 

03:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400 AGP (rev 
85) (prog-if 00 [VGA])
      Subsystem: Matrox Graphics, Inc.: Unknown device 0d43
      Flags: medium devsel, IRQ 18
      Memory at d0000000 (32-bit, prefetchable) [size=32M]
      Memory at d3000000 (32-bit, non-prefetchable) [size=16K]
      Memory at d4000000 (32-bit, non-prefetchable) [size=8M]
      Expansion ROM at <unassigned> [disabled] [size=128K]
      Capabilities: [dc] Power Management version 2
      Capabilities: [f0] AGP version 2.0 

my goal is to run X on the nvidia card and use the matrox card for tv-out 
only with mplayer and directfb. 

loading the matroxfb_base module renders the text-mode console on the nvidia 
card unusable. at the same time x with the nvidia.o module works fine 

the output on the tv-out plug of the g450 is garbled, too 

syslog of "modprobe matroxfb_base":
PCI: Enabling device 03:00.0 (0000 -> 0002)
matroxfb: Matrox G450 detected
matroxfb: MTRR's turned on
matroxfb: 640x480x8bpp (virtual: 640x26214)
matroxfb: framebuffer at 0xD0000000, mapped to 0xf9ea9000, size 33554432
Console: switching to colour frame buffer device 80x30
fb0: MATROX VGA frame buffer device 

then i load the i2c-matroxfb module:
i2c-algo-bit.o: i2c bit algorithm module
i2c-algo-bit.o: Adapter: DDC:fb0 #0 on i2c-matroxfb scl: 1  sda: 1 -- 
testing...
i2c-algo-bit.o:1 scl: 1  sda: 0
i2c-algo-bit.o:2 scl: 1  sda: 1
i2c-algo-bit.o:3 scl: 0  sda: 1
i2c-algo-bit.o:4 scl: 1  sda: 1
i2c-algo-bit.o: DDC:fb0 #0 on i2c-matroxfb passed test.
i2c-core.o: adapter DDC:fb0 #0 on i2c-matroxfb registered as adapter 2.
i2c-algo-bit.o: Adapter: DDC:fb0 #1 on i2c-matroxfb scl: 1  sda: 1 -- 
testing...
i2c-algo-bit.o:1 scl: 0  sda: 0
i2c-algo-bit.o: DDC:fb0 #1 on i2c-matroxfb SCL unexpected low while pulling 
SDA low!
i2c-matroxfb: VGA->TV plug detected, DDC unavailable.
i2c-algo-bit.o: Adapter: MAVEN:fb0 on i2c-matroxfb scl: 1  sda: 1 -- 
testing...
i2c-algo-bit.o:1 scl: 1  sda: 0
i2c-algo-bit.o:2 scl: 1  sda: 1
i2c-algo-bit.o:3 scl: 0  sda: 1
i2c-algo-bit.o:4 scl: 1  sda: 1
i2c-algo-bit.o: MAVEN:fb0 on i2c-matroxfb passed test.
i2c-core.o: adapter MAVEN:fb0 on i2c-matroxfb registered as adapter 3. 

and the fusion module. 

next step is starting mplayer with -vo dfbmga. now the video appears 
correctly on the tv connected to the tv-out plug - but the output of the 
nvidia card switches to that weird half transparent text-console and only 
switches back to X when mplayer stops. 

i am using cvs-versions of mplayer and directfb from yesterday, kernel 
2.4.22-pre10 with fusion-patch and matroxfb-fullmemory-patch applied 

matroxfb compiled in makes no difference to as loaded as module, if compiled 
in the console is messed up earlier of course. 

is what i am trying to do possible? is directfb the way to do it? or is 
there a better way? (maybe the mga_vid code?) how do i tell the matroxfb 
module to leave the nvidia card alone? 

i have read almost everything i could find about the g450 card on the 
directfb-users mailinglist archive. also i tried google-web and -groups. so 
far there seems to be noone who got a setup similar to this and wrote about 
it. 

at this point i started reading around in the matroxfb_base.c code but as my 
c-knowledge is not really existing i couldn't make much of it. 

i'd be happy to get any pointers at all ;) 

btw, english is not my mother-tongue, so i hope the expressions i used do 
not offend anyone or keep him/her from replying. 

thanks in advance
