I have a i830 also.. If you turn off KMS the old framebuffer driver works fine.... obviously, this means 2.6.34 and beyond are unusable at this point in time on the i830 although I did get the blacklight on in the terminal using 2.6.35 with KMS on .... My Toshiba 1200-S212 "i830" only has 8 megs of video ram, which I concluded was not enough to run the new drmframebuffer drivers... Than intel introduced the virtual memory stuff, but AFAICT it's not active on the i830 yet....
"from memory" (so forgive the incomplete description) both pipe A and pipe B are active when cloning the xorg.conf device and [screen or monitor] sections... but I also haven't attached an external monitor to look at how it behaves...

Can you attach the dmesg from a kms boot? Cheers, Julien -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
