Hi,

I tried the kernel (only the kernel) from xorg-edgers, but that does not improve things:
Linux xenon 2.6.34-1-generic #4~oga1-Ubuntu SMP Thu Apr 22 23:58:02 UTC 2010 x86_64 GNU/Linux

I have no sound over HDMI either. I get this message in dmesg:
HDMI hot plug event: Presence_Detect=1 ELD_Valid=0
I though that maybe sound and video interfere, so I blacklisted the snd_hda_codec_intelhdmi module, but it did not help for the video either.

I tried the ppa-mainline kernel linux-image-2.6.34-020634rc5-generic_2.6.34-020634rc5_amd64.deb: no progress.

While rebooting I noticed that grub is shown on the external monitor with the HDMI cable, and also the cursor is blinking there for a while. Then the screens start flickering a bit and the external display turns black. So I removed the ^plymouth-* packages (not plymouth and libplymouth) hoping to see more. When booting, initially the external screen shows a blinking cursor while the internal display is black. Then something switches to the internal screen and the external one is black. There are a few message lines flashing up on the internal screen, something about fsck, before X/gdm starts. I do not know if that is useful information. I could also try using the vesa driver (removing the xorg-server-video-intel driver).

Best regards,

Alexander
