Alpha list,
This may not be alpha-specific. I don't know. Perhaps Gentoo has an
appropriate forum?
To make my radeon work, I had to build the X driver into the kernel.
This forced me to build a radeonfb module. The framebuffer module makes
my console 1280x1024 32bit with 160x64 text.
I would really, really, really prefer something else on my 17"
non-widescreen monitor. I can't figure out a way to do it.
For X, xrandr can switch to a variety of auto-detected modes. The
console framebuffer only gives one choice by default. So, I tried fbset
and /etc/fb.modes. Regardless of geometry, the only timings line that
works is 0 0 0 0 0 0 0. For example
mode "800x600"
geometry 800 600 800 600 24
timings 25000 88 40 23 1 128 4
hsync high
vsync high
endmode
That gives "ioctl FBIOPUT_VSCREENINFO: Invalid argument" as a result.
The timings listed are from formula and are confirmed by an old example
posted at https://github.com/Distrotech/fbset/blob/master/etc/fb.modes.ATI
(800x600 60HZ)
Changing timings to all zeroes removes the error, but gives me an
800x600 piece of a 1280x1024 screen.
So, I tried passing a parameter to the module. The kernel loads it
automatically while booting. I made a radeonfb.conf file in
/etc/modeprobe.d, but nothing worked.
It seems strange that I can rmmod radeonfb and fb_ddc and the console
remains unaffected.
What am I missing? Is it not possible to change my console resolution?
I need help.
Thanks, DW
