TwinView and Mandrake 9.2
I have TwinView configured successfully with Mandrake 9.1 on my GeForceFX 5600. My desktop stretched between the two monitors and they are even set at different resolutions. My primary monitor is attached to the VGA port and the secondary monitor is attached to the DVI port with a VGA adaptor. I added the following to my XF86Config-4 file for it to work (secondary monitor is a 15" Compaq 150):

Option "TwinView"
Option "SecondMonitorVertRefresh" "50.0-100.0"
Option "SecondMonitorHorizSync" "31.0-48.0"
Option "MetaModes" "1280x1024,1024x768"

The problem is that adding the same options does not work in Mandrake 9.2 even though nothing else has changed with my configuration. In looking at the log file it appears that the incorrect refresh rates are being passed to the monitors and that perhaps CRT-0 and CRT-1 are getting mixed up.

I have posted some in formation on the Mandrakeclub forum which can be found here:

I have gone back to using Mandrake 9.1 as I could not get both of my monitors configured in 9.2. Any help is appreciated. Thanks.

ME two
I have that same problem ,
I tired everything. I just tried to switch both CRT sreen conectors my 17" aoc who works fine one the DVI converted to analog port. and my 15" old Lite-on on the analog VGA port.

so when I tried the Lite on on the DVI port (with converter) the power went on , but I didn't get anny picture , ass soon as Xwindows is started.

Maybe this is the problem why twinvieuw wont work either. Could you check if your 15 " works, if you put it alone.
