Replying to [comment:5 axeld]:
I have the following graphics hardware on one of our PCs:
{{{
device Display controller (VGA compatible controller, VGA controller)
[3|0|0]
vendor 1002: ATI Technologies Inc
device 5a61: RC410 [Radeon Xpress 200]
}}}
This is normal PC with onboard graphics with external LCD Monitor attached
to VGA output.
I observe the above described behavior with r35333. Just after the system
finishes coloring all boot icons the monitor first display an "Invalid
signal range" message for one second than goes to "No signal" state. It is
only possible to boot with fail-safe video mode.
> What happens if you press "Command + Control + Escape" after a while?
No effect on the screen but lot of tracing in the debug output. Look into
attached softdc-07-2.log for details after "sync: device 3 couldn't sync:
Operation not supported" line. Yes, I have pressed Alt-Ctrl-Esc and Ctrl-
Alt-Esc twice. :-)
> Also, if that doesn't help, can you log into the system, and execute the
following application?
The specific of this PC is that there is the only possibility to load
Haiku - booting from the Live-CD. I have compiled this "DPMS reset"
program but with "return 1;" and replaced the
/boot/system/bin/ReadOnlyBootPrompt with it's executable. ;-) I do this
just to automaticaly force it to be started during loading Live-CD
session. Unfortunately that doesn't help to switch the display on.
