Hi all,
Just wondering is anybody could test something for me because I would
like to eliminate a possible hardware problem.
What I need is somebody with either a G400 DualHead or DualHead MAX and
a second monitor to run the following commands and tell me if they have
rubbish or good output on the second monitor.
modprobe matroxfb_maven
matroxset -o 1 128
Turn on the output to the second head
matroxset -f /dev/fb1 -m 2
fbset -fb /dev/fb1 "[EMAIL PROTECTED]"
I get an 1152x864 / 48 Hz Out of range error on second monitor, a bit
strange, possible incorrect dot clock
fbset -fb /dev/fb1 "[EMAIL PROTECTED]"
ioctl FBIOPUT_VSCREENINFO: Invalid argument
fbset -fb /dev/fb1 "[EMAIL PROTECTED]"
gives this image http://www.linuxowl.com/images/[EMAIL PROTECTED]
I'm pretty sure that I'm using the correct commands but something is wrong.
Redirecting /dev/fb0 to the second head works. with
matroxset -f /dev/fb1 -m 0
matroxset -f /dev/fb0 -m 2
Reset the frame buffer back to the first head
matroxset -f /dev/fb0 -m 0
matroxset -f /dev/fb0 -m 1
/etc/fb.modes is:
