Strange Dual-head problem

[Tamagotono]

OK here's the problem...
I am running a dual head configuration with a 15" and a 17" LCD monitors. The system works like a champ except for 2 problems...

When I first turn on the computer and boot into Kubuntu, I get no display! The primary display has a green light indicating that there is a signal but there is nothing on the screen, the secondary display has only an orange light indicating that there is no signal. Normally I would say that there is something wrong with my xorg.conf file but here is where it gets weird... after I hit the reboot (not turn off then back on) the computer either after booting into windows and rebooting or just hitting the reset button after the displays go blank, it will boot just fine into my dual-head display.

When both displays are blank I cannot even switch into console mode and I hear no startup sounds.
I am running an ATI Radeon 9600 with Kubuntu Dapper Drake 64Bit.

I have been pounding my head against the wall on this problem for a couple of months and still cant get it to work.

Anyone have any suggestions for me to try?

Re: Strange Dual-head problem

My guess would be that you have found a bug in Dapper. I would suspect that handling dual head displays is something that is not high on the list of the developers who are planning to release Dapper in June. I would (a) report the problem to the developers, and (b) go back to using Breezy until Dapper is closer to its release.

Re: Strange Dual-head problem

I think I had the same problem.  I found that it occurred when using the fglrx drivers.  So I changed the fglrx entry in xorg.conf to ati.  Works fine except the mouse pointer stays the same as it is when it leaves the primary monitor. (i.e. If it's a normal pointer it won't change to a hand over web links and if it changes to a resize pointer it will stay like that).

I'm hoping the mouse issue is a Dapper problem but fglrx on two screens would be nice!

Actually, I've just had a go at changing to fglrx and X starts ok but the windows get all messed up.

Here's my xorg.conf working with the mouse problem using ati:
