Subject: Matrox framebuffer dualhead and utilities


Hello,

I'm trying to set the Matrox framebuffer to dualhead or TV output,
but the utilities mentioned in the docs seem to be outdated (ioctl failed
with incorrect command). Any idea about where to get up to date tools?
I'm using kernel 2.4.2-ac20 (quite stable 5 days uptime with heavy DRI
testing and heavy disk working).

Thanks

- german

matroxset-0.3 is latest one. You are probably doing something wrong:
(1) With fbset you are trying to use 8bpp or 24bpp color depth.
Secondary
head supports only 16/32bpp.
(2) You did not insmod all needed modules if you compiled matroxfb as
modular (you should compile everything into the kernel...)
(3) You are trying to do some illegal thing, like connecting both
/dev/fb0 and /dev/fb1 into same output...
