Thanks Andy!
All sorts of interesting things happen:
(Relevant to the recent X/Autodetect thread)
I have been experimenting with a second monitor, not a projector.
But it feels very similar to me...)
1) radeon->vesa driver for my radeon card
This drops glxgears from 600->175, and dri support goes.
mplayer knows xv will not work, so picks x11. Which means I
do get a display, without having to think, even if it is
not a nice one.
However, the alt-F8 works as it did on RH-9. It seemed to be
disabled before. So I can choose laptop, projector or both.
2) apm on/off does nothing for me.
3) apci off/on does nothing for me.
4) Start X WITHOUT the external display, and then plugging it in,
fixes the problem.
So it seems that it recognises the second screen and tries to
do something clever in consequence. So I can summarise:
A) Start X with projector connected
Screen position correct, no clipping, but 680x480 only.
xv output only displayed on laptop.
In XFree86.0.log I notice:
(**) RADEON(0): *Mode "1400x1050"
(**) RADEON(0): *Mode "1280x1024"
(**) RADEON(0): *Mode "1280x960"
(**) RADEON(0): *Mode "1152x864"
(**) RADEON(0): *Mode "1024x768"
(**) RADEON(0): *Mode "800x600"
(**) RADEON(0): *Default mode "640x480": 25.2 MHz, 31.5 kHz, 60.0 Hz
(II) RADEON(0): Modeline "640x480" 25.20 640 656 752 800 480 490 492
525 -hsync -vsync
(**) RADEON(0): Default mode "320x240": 12.6 MHz, 31.5 kHz, 60.1 Hz (D)
(II) RADEON(0): Modeline "320x240" 12.60 320 328 376 400 240 245 246
262 doublescan -hsync -vsync
B) Start X without, then plug-in
xv works nicely
screen display slightly misplaced
1400x1050 seems to work on this monitor.
Does that suggest anything about the source?
