I found a solution to the problem. Adding
Option "PanelSize" "1680x1050"
Option "MonitorLayout" "TMDS,NONE"
made the display work correctly. IIRC this was needed with XOrg 6.9,
but wasn't needed with 7.0 (because it was intelligent enough to
autodetect correctly?). This seems to be a regression in 7.1.
Both the PanelSize and MonitorLayout need to be exactly as above. If
either is commented out, or I change MonitorLayout to just "TMDS", the
monitor powers off.
Just in case it's affecting anything, I'm adding
append="video=radeonfb:[EMAIL PROTECTED]"
in my yaboot.conf in order to get a fullscreen framebuffer.
Regards,
Roger
