Description John Steele Scott 2005-01-11 19:44:04 UTC
X Window System Version 6.8.1.901 (6.8.2 RC 1)
kernel: 2.6.9-gentoo-r1 with benh's iBook sleep patch #4

If I attach a monitor to the VGA-out port, X correctly detects it and sets
itself up for dual-head operation. Bravo. The picture on the external CRT is
fine, but the image on the iBook's panel is unstable; sometimes it wobbles up
and down, and always there is an apparent flickering down the left-hand side.

The image looks the same as how it used to look with older versions of Xorg if
you had UseFBDev=false. But with UseFBDev=false, single head mode works fine.
It's only with a second head attached that the flickering occurs.

I will attach my xorg.conf and log file.

Sorry, looking further into this, I can't be sure of what version is giving me
this problem. I just rebuilt a more-or-less vanilla Xorg 6.8.2 RC1 driver, and
it's not doing the flickering (although it doesn't init the second head at all :().

I will reopen or post a new bug when I can figure out what's going on.
