External Monitor on T60p

[daneelgiskard]

Hi all,

I have succesfully installed leo4all on my T60p. I use ATIinject for my FireGL 5200 as described here: http://forum.thinkpads.com/viewtopic.ph ... d9e465d256

This works all very nicely, but I'm struggling to get my external display to work. The following works: I connect my external display (A Dell LCD) through the VGA out port on my T60p. In OS X I click on "Detect Displays" in the Display Preferences. This will successfully and correctly detect my external monitor as a Dell 1907FP and will also set the correct resolution (1280x1024@60HZ) for this monitor.

However, the external monitor stays black. I cannot get OS X to actually display something on it. I know that it is there, I can actually drag and drop windows into the (black) monitor from my notebook display. But nothing is displayed there.

Can anyone help me?

This is the (what I think is relevant) excerpt from my Info.plist:

Any help would be greatly appreciated!

Many thanks and all the best,

i have the v5250

for external display to work, i have to have the monitor plugged in and turned on when i turn my thinkpad on - i.e. so i see the whole bootup on both screens

external display doesn't work for me when i plug it in and the machine is already running, or after resuming from sleep.

have you tried plugging the screen (turned on) into your laptop before turning the laptop on?

[daneelgiskard]

Dear Chris,

many thanks for your reply. I've tried this already, both with and without the docking station. My second monitor never receives a signal, not even during boot (although it is detected correctly by OS X as described in my original post).

Do you also use ATIInject as your graphics driver? Can you maybe share your config files (Info.plist, ...) with me? I think it must be something in the config files, since OS X correctly detects the monitor, but it doesn't seem to receive a signal.

Many thanks and all the best,
Michael

i don't use atinject - i use the ati 1000 drivers and edid strings which i pulled myself using pheonix.

what screen resolution do you have? mine is 1400x1050 - if yours is the same then i'll grab the files i'm using and upload them for you to try

[daneelgiskard]

Dear Chris,

yes, my resolution is the same. It would be great to get those files. Thank you very much in advance.

Cheers,
Michael

i guess first thing to try would be efi strings - here's my com.apple.Boot.plist
