[Linux-fbdev-users] Boot options for radeonfb?
|

Greetings!
I have just recently begun to try out radeonfb. I have it compiled into my
2.6.9-rc3 kernel (I need some of the usb improvements, hence rc3).
It works great with my laptop and lcd screen, but I can't get it to adjust
itself for when I have my CRT plugged in. I can't find any docs under
Documentation/fb/ for this particular driver.
Laptop: Dell Inspiron 8600
ATI card: 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]
LCD: I can't find the brand, but it's 16:10 aspect with default 1680x1050
CRT: Dell P1130 1280x1024@75 max
I have tried to pass parameters at boot through lilo. I do get display on
the CRT, but it is unuseable.
append="video=radeon:"
It detects my LCD settings and applies them to my CRT display. I only get
the 'middle' difference between 1680 and 1280 on the horizontal.
append="video=radeon:1280x1050-24@75,crt"
I get fonts so large I can read them across the room... what is displayed
to the CRT, anyway. Everything is cut off both ends.
append="video=radeon:1280x1050-24@75"
It just completely ignores this and goes with the default 1680x1050-8@60
It is seeing the CRT connection, but seemingly making no adjustments for
it, and the above commands were guesses on my part, due to lack of
documentation as to driver options.
