Hello, I have a G400 DH, and i'm trying to run the
frambuffer stuff to make it output to the TV. Output
does work in X, but i would prefer to get it working
through the framebuffer.
Basically my problem has been that output onto the TV
just plain fails. i can do 'matroxset -f /dev/fb1 -m
0' to disconnect it, but matroxset -f /dev/fb0 -m 3'
fails with ioctl failed.
I have been having the wierdest problems, but after
looking through my settings it seems to come down to
the Maven chip wasn't being found. Everything is
compiled into the kernel, I2C, bit-banging, and all
the g400 stuff.
Here is everything from dmesg relating to the g400:
i2c-core.o: i2c core module
i2c-dev.o: i2c /dev entries driver module
i2c-core.o: driver i2c-dev dummy driver registered.
i2c-algo-bit.o: i2c bit algorithm module
i2c-proc.o version 2.6.1 (20010825)
matroxfb: Matrox G400 (AGP) detected

i2c-core.o: driver maven registered.
matroxfb_crtc2: secondary head of fb0 was registered
as fb1
I'm wondering if anyone else has had this problem, i
am using kernel 2.4.18-xfs-1.1. Also, does anyone
know which version of the 2.5.x kernels has a
compilable matroxfb? 2.5.59 didn't want to compile,
but i noticed the drivers have changed, although it
seems like it might just be a cleanup. I was hoping
maybee the new code would work though.
Any help would be appreciated, or if anyone needs more
information to try and figure this out.
Erik
