Hi,
I've connected an intel mac mini with a Panasonic PT AX-100E LCD beamer.
While this worked fine using the analog cable (either with a 1280x768 or
a 1280x720 resolution) using the digital signal with a DVI to HDMI
adapter doesn't work for high resolutions. 1024x768 and lower
resolutions are fine while higher resolutions don't display any image.
Looking at the log the calculated vert refresh rate seems to be wrong
since it's always zero:
For the 1280x768 mode:
(II) intel(0): Modeline 1280x768x0.0 80.14 1280 1344 1480 1680 768 769
772 795 (47.7 kHz)
(II) intel(0): Adjusted mode for pipe A:
(II) intel(0): Modeline 1280x768x0.0 80.14 1280 1344 1480 1680 768 769
772 795 (47.7 kHz)
chosen: dotclock 160457 vco 1604571 ((m 117, m1 20, m2 5), n 5, (p 10, p1 1,
p2 10))
and for the 1280x720 mode (coming from a handcrafted modeline in xorg.conf):
(II) intel(0): Modeline 1280x720x0.0 74.52 1280 1312 1368 1676 720 724
730 750 (44.5 kHz)
(II) intel(0): Adjusted mode for pipe A:
(II) intel(0): Modeline 1280x720x0.0 74.52 1280 1312 1368 1676 720 724
730 750 (44.5 kHz)
chosen: dotclock 148800 vco 1488000 ((m 93, m1 15, m2 6), n 4, (p 10, p1 1,
p2 10))
The x0.0 looks like a driver bug. The log says further down for these
tow modes:
(EE) intel(0): I830 Vblank Pipe Setup Failed 0
(EE) intel(0): I830 Vblank Pipe Setup Failed 0
while everything looks o.k. for 1024x768.
Any ideas?
Does xserver-xorg-video-intel 2.2.0 from unstable help?
