I fixed this by actually editing the macmodes.h file and including the
timing for this particular mode and setting it as the default mode at
boot time, but the timing seems a bit off. I only get correct timing if
I run a fbset "1280x720-50" command after a boot.

Are there any assumptions the radeonfb code does wrt to timings that
I've missed? And why does the radeonfb driver use it's own mac specific
timings? Is the old radeonfb driver better in this respect?

[Linux-fbdev-users] problems configuring 1280x720 w radeon

[Torgeir Veimo <torgeir@po...>]

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.

And dmesg output, for completeness;

I am using the analog connector on this card, connected to a Sanyo PLV
Z2 projector. It advertises wrong EDID data when in PC mode. I can only
get it to advertise 1280x720 on the DVI port, but then I am restricted
to 60Hz, to get a tearing free picture. This is why I am using the
analogue port.
