I have tried to use the matroxfb (Matrox G200 Millenium 8MB SDRAM) with
my FixedFrequence Monitor HP98751A(1024x768@60Hz). I use the
sync_on_green option and translated the Modeline from X11 like explained
in the Docu.
XF86Config:
# Modeline für HP 98751A
ModeLine "1024x768" 64.1088 1024 1088 1216 1344 768 771 775 795
+hsync -vsync
lilo.conf:
image = /boot/vmlinuz-2.2.0-pre6
label = linux
append =
"video=matrox:noinit,nohwcursor,nopan,mem:8192k,sdram,vesa:0x105,righ
t:64,hslen:128,left:128,pixclock:15598,lower:3,vslen:4,upper:20,sync:0x21"
root = /dev/hda3
With X11 the is no problem and everything works fine. With matroxfb the
screen scroll through vertikal. I've tried to fix it inverting the
v/hsync. It doesn't work. Now I've played around with the fbset-2 tool.
The Screen doesn't run through anymore but it's still looking terrible.
fbset output is:
mode "name"
# D: 64.111 MHz, H: 47.701 kHz, V: 50.531 Hz
geometry 1024 768 1024 768 8
timings 15598 128 64 170 3 128 3
hsync high
gsync true
endmode
The HSYNC-Rate is ok, but the VSYNC-Rate is much too low(Should be
60Hz).The Monitor should not able to output this settings. If tested
this settings with my X11 and they don't work.
So I think this is a bug in matroxfb. I talked to an other guy on
de.comp.os.linux.hardware and he told me that his Millenium I just
working fine, but he don't use the sync_on_green.
I've just no idea how to fix this problem.
