I booted with a Linux DVD and Ultrabase. Linux recognizes the external monitor and identifies it correctly as Samsung 22", but the monitor stays black with nothing displayed in either extended display mode or clone screen mode.
Since it does not work with Linux either, it does not look like a Windows driver problem.
Since it does not work with neither the VGA port on the tablet itself, nor the VGA port on the Ultrabase, seems to imply that its not the VGA port either.
Does that imply a faulty chip on the motherboard? It is surprising that this problem has happened to lot of different models of Lenovo machines, not just X61.
Here is a post for similar problem on T60: viewtopic.php?f=29&t=77897&view=next
. There are numerous others on the web.
If Lenovo has figured out the problem, would be good to know what is causing and what workaround will work. Do I need to get a USB to VGA or DVI Adapter? If I got one, will it work, or whatever is causing this problem, will cause a problem with the adapter too?
Which of the few adapters out there works well?
Thanks for any suggestions.
