I am trying to configure a 1280x720 resolution at 50Hz with a radeon
9100 QM card.
I have set up a mode in fb.modes that works if I set it with fbset after
boot, but then the "usable" text area doesn't span the entire
resolution, only about half the width and twothird the height, and
positioned to the upper left.
# 50 Hz
mode "1280x720-50"
# D: 61.80 MHz, H: 37.50 kHz, V: 50.00 Hz
geometry 1280 720 1280 720 16
timings 16181 218 110 20 5 40 5
endmode
When I try to use this mode at boot time, nothing happens. I have the
following settings in grub.conf;
title Fedora Core (2.6.5-1.308custom)
root (hd0,2)
kernel /boot/vmlinuz-2.6.5-1.308custom ro root=/dev/hda3
video=radeonfb:xres:1280,yres:720,depth:16,left:218,right:110,hslen:40,
upper:20,lower:5,vslen:5,pixclock:16181
Any idea what I am doing wrong? I have both matroxfb and radeonfb
compiled into the kernel.
