I have found the solution to this tiring problem. I am running the final
Ubuntu 9.10 on a MacBook 2,1 and I can successfully fix this issue with
a 100% success.
You need to do the following (remember to disable mirrored monitor first):
1. Plug in your external monitor
2. Start your MacBook and start boot into Ubuntu
3. Close the lid of your MacBook
4. You have now booted in and logged in (the flickering is now present)
5. Now, restart your machine and boot into Ubuntu (DO NOT OPEN MACBOOK LID!!)
6. Your now booted into Ubuntu again, the flickering is gone!
This I am able to do with success.
I have an SyncMaster 226BW and my MacBook is a revision 2,1.
I hope this helps others as well as it helped me!
