    24" Apple LED cinema, Z68 Pro3-M, iGPU, 11.04

    I can't seem to get my system to recognize my 24" Apple LED Cinema Display (DisplayPort) with a ASRock Z68 Pro3-M motherboard (i7 2600k, 1.40 firmware) using the iGPU/DisplayPort running Ubuntu 11.04 2.6.38-10-generic with latest updates. The system boots and runs (can ssh into it) but there is no display. The same system running Windows 7 x64 works fine. A DVI monitor also works fine. Xserver-intel driver sees the display but can't set any modes for it.

    Log files dmesg lshw Xorg.0.log

    Anyone have any idea what's going on here?

    Here is an excerpt from Xorg.0.log:

    I'm fairly sure there have been lots of HDMI/Displayport problems recently with the intel driver.
    Your problem sounds like the same thing (?).

    I guess the apple design does not have a DVI connector..

    You could try the more cutting edge drivers from xorg-edgers ppa.
    I have found it very reliable last 18 months.

    Thanks for the suggestion BicylerBoy but it didn't work with the latest from ppa: xorg-edgers/ppa either.

    Do you know the significance of this warning?

    [ xx.xxx] (WW) intel(0): Unable to find initial modes

    What is it looking for and where is it looking for it?

    The Apple LED Display is DisplayPort only. It works on another system running 11.04 that has a Nvidia 880M gpu/driver.

    Re: 24" Apple LED cinema, Z68 Pro3-M, iGPU, 11.04

    I am having this same issue on Gentoo.
    I'm using linux-2.6.38-gentoo-r6.
    I have tried xf86-video-intel-2.8.1 and xf86-video-intel-2.9.1.
    I am now upgrading to linux-2.6.39-gentoo-r2 to see if it helps.

    I am on a macbook pro using a 27" Apple LED Cinema display through displayport

    The upgrade to 2.6.39 didn't help.
    I might try cloning the git repository for the intel driver and using the latest.

    I decoded the EDID data and created a mode using xrandr. I get an error still.

    Code:
    $ xrandr --output DP1 --newmode "1920x1200" 154.0 1920 1968 2000 2080 1200 1203 1209 1235 -HSync +VSync
    xrandr: Output DP1 is not disconnected but has no modes
    xrandr: Output DP1 is not disconnected but has no modes
    $ xrandr --addmode DP1 "1920x1200"
    xrandr: Output DP1 is not disconnected but has no modes
    $ xrandr --output DP1 --mode "1920x1200" --verbose

    It may be a 'long shot' but..could try to update the mobo BIOS.
    There was a thread of this forum in April about similar problem.

    One of my intel mobos has had 14 updates (some minor) in 2 years..
    One update fixed the on-board network adapter when it stopped with kernel update.

    I'm assuming you are on a new snb 13" macbook pro that only supports the Intel HD 3000 graphics? Let me know how you make out. My solution was to run down to Best Buy and buy a cheap DVI monitor since I can't use my $1000 one.
