DPMS kicks in at the wrong time

DPMS kicks in at the wrong time

System:
P II, ASUS P2L97-S motherboard (LX chipset plus onboard SCSI).
Currently I740-based video card, Sony Multiscan SFII.
Linux possum 2.4.0-test12 #6 Wed Dec 13 13:43:54 WST 2000 i686 



It's happened on this machine with every kernel I've tried it, right back to 
(I'm pretty sure) 2.1 days.

Whenever I try frame buffer support, this is what happens:
1) I can boot up with the logo, lots of characters across the screen, and 
Linux happily writing on my console.

2) I can switch to a graphics display, either with KDM/GDM/XDM, or by logging 
in and starting X.
3) When I then switch back to a virtual console, the screen blanks and 
switches to power-saving mode.



Here's the config:

Which powersave mode? There are three, IIRC. You can tell them apart
by the color of or whether the light blinks on some monitors.

If the monitor is set to a modeline that it knows is crazy it might
turn itself off automatically instead of trying to display it. That
is, the framebuffer driver or XFree86 is probably not reseting some
values it should.
