8:07 a.m.
Laptop attached to docking station, and through that to an external
display.
Booting F8, external display behaves normally at first, but when
graphical stuff starts, it does some flickering (like a TV in need of
horizontal hold adjustment) then goes blank and stays blank. Laptop
display continues to work normally.
I'm only trying to display the same desktop simultaneously on both
displays. No split desktops or double desktops, or anything fancy.
It all worked properly with FC5, and subsequent upgrades to FC6 and then
F7. Problem appeared only on upgrade to F8. All F8 updates applied.
Everything still works normally if I boot Windows XP instead of F8.
Config is: Compaq Evo N1020v laptop with Radeon IGP 340M graphics.
External display is just an old Gateway EV500 15" CRT. Both displays
are 1024*768.

New subject: Fedora 8 doesn't see my external monitor
xrandr reports "VGA-0 disconnected", but it certainly is connected, and
both Ubuntu and XP can find it OK on the same hardware.
I suspect a very recent ATI driver update has made this worse: xrandr
used to find the screen, though it was blank. I could make it mirror
the laptop display by saying
"xrandr --output LVDS --mode 800x600" followed by
"xrandr --output LVDS --mode 1024x768"
But now nothing seems to work...

I have the following device section:
Section "Device"
Identifier "Videocard0"
Driver "radeon"
Option "MonitorLayout" "LVDS, CRT"
Option "CRT2HSync" "30.0-85.0"
Option "CRT2VRefresh" "50.0-150.0"
Option "CRT2Position" "Clone"
Option "MetaModes" "1400x1050-1400x1050"
EndSection
You'll need to replace 1400x1050 and find the
proper values for the monitor for HSync and
VRefresh.

You might like to experiment with the xrandr command. It can dynamically
change resolutions, add and remove extra monitors, etc. A few starting
points:
man xrandr

You write that you didn't have this problem in F7; neither did
I at first, not until a later update. Then it was necessary to
add these lines into xorg.conf

The ATI driver is seriously screwy.

Yeah, I got a little surprise yesterday from xrandr during a presentation on
my F8 laptop. I had just disconnected the projector from the external
monitor connector on my Dell 640m, and was taking notes in a kmail composer
window, when all of a sudden the screen went black and I was returned to the
login screen. Good thing kmail keeps what you were doing.
What had essentially happened, I think, is that the screen resolution changed
from the 1024x768 it was using while the projector was connected to the
native widescreen resolution; this apparently triggered a logout or similar.

Thanks. I've taken this example, changed the resolution to 1024x768 and
the refresh rates to those recommended by Gateway (Hsync 30.0-69.0,
Vrefresh 50.0-110.0)
Sadly, it seems to make no difference.
Any further suggestions...?
