Maybe the problem is here:

file: src/i830_quirks.c

/* Lenovo T61 has no TV output */
{ PCI_CHIP_I965_GM, 0x17aa, 0x20b5, quirk_ignore_tv },
Comment 2 c4pp4 2008-10-06 19:31:06 UTC
I think it's similar like here: https://bugs.freedesktop.org/show_bug.cgi?id=14432
Comment 3 Gordon Jin 2008-10-07 06:14:41 UTC
Yes, it looks similar. So reassign to Zhenyu.
Comment 4 Wang Zhenyu 2008-10-08 18:11:57 UTC
You can simply try removing that quirk line, which we should do. As I believe current video bios data parsing already give us the right answer.
Comment 5 Wang Zhenyu 2008-10-08 18:28:00 UTC
Removed that one in master now.

    Remove Lenovo T61 TV quirk
    BIOS already says no integrated TV, and this quirk blocks TV
    on R61i which has the same subdevice id as T61.

Thank you very much, it works!
