Yes! It works! I can't even tell you how relieved I feel without sounding like a lunatic. Here are the details of the experience: 1. added the ppa:kernel-ppa/ppa repository to apt-get 2. installed linux-generic and linux-generic-headers version 2.6.39-0.4~20110419 3. logged in using the no effects profile 4. plugged in Mitsubishi DiamondPoint NX86LCD 5. immediately it extended the screen, with the monitor as the overflow desktop 6. successfully moved a window into that part of the desktop 7. selected mirror screens 8. at first, monitor went black 9. changed to a lower resolution, apply, then back to highest resolution, then apply 10. same image in both monitors (I suspect the fiddling was probably me not being patient enough) 11. logout out and tried the same thing in unity 12. unity flakes out a bit while the image is getting setup in the external monitor and even crashed, but then after a few seconds, it all settled out and I could use both monitors, mirror and non-mirror 13. repeated the same test on a Samsung SyncMaster 2333HD 14. the display synced much quicker in both cases 15. unity was still crashing during the switch, but eventually worked itself out...I suspect that problem has to do with unity The end result is, the new kernel works. The transitions could be smoother, but that could be dependent on the monitor and how it responds to the input signal. But I'm just speculating.

For the record, I tried out the intel driver from the elderberry ppa using the older kernel (the one from natty beta2) and it did not fix the problem. I still got: [ 63.990093] [drm:ironlake_crtc_disable] *ERROR* failed to disable transcoder [ 164.540158] [drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting [ 164.950081] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up [ 164.952644] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up The xset trick didn't have any affect either.

Hi Dan, Good to hear the mainline kernel solved it. Would you be willing to do some additional testing to isolate which specific patch fixed it? If so, the kernel team might be able to backport that fix to include in natty. Directions for isolating kernel patches via git bisection are documented here for you: https://wiki.ubuntu.com/Kernel/KernelBisection If you can find a commit where the kernel switches from failing to working, that'll give the kernel guys a strong indication of what needs pulled from upstream to get your system working by default with natty. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete = Confirmed ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Confirmed = Incomplete ** Changed in: linux (Ubuntu) Status: New = Incomplete ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete = In Progress ** Changed in: xserver-xorg-video-intel (Ubuntu) Importance: Undecided = Medium ** Changed in: linux (Ubuntu) Importance: Undecided = High -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/762855 Title: [sandybridge-m-gt2+] Display on external monitor (vga) is black on 13 MacBook Pro 8,1 (x86_64) ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I gave it a shot, but I must admit I'm a bit lost since I'm straddling between two kernel versions 2.6.38 and 2.6.39. I'm not quite sure where to go. I arrived at git://kernel.ubuntu.com/ubuntu/ubuntu-oneiric.git. I installed various kernel builds from the 2.6.39 line. Here are my results: v2.6.39-rc1-natty - broken 2011-04-08-natty - working (daily build from 2011-04-08) v2.6.39-rc3-natty - working I examined the commit messages. I'm going to take a wild guess, but it looks like one of these: 7ccb4a5 drm/i915: Re-enable self-refresh 18b2190 drm/i915: allow 945 to control self refresh (CxSR) automatically 0de009c drm/i915/crt: Remove 0xa0 probe for VGA Folks have been busy on i915 between Ubuntu-2.6.39-0.0 and Ubuntu-2.6.39-0.2, which is where the fix seems to be.

Hi Dan, You mentioned in your description specifically that the issue is seen as of the 2011-04-16 nightly; by this comment do you mean to imply that prior to 4-16 this issue is not reproducible? If that is the case, please tell me the most recent working version; I can then examine what packages changed between that version and 4-16 and we can see if there is a regression. Otherwise, can you also test the following after reproducing the bug: xset dpms force on If that works (heck, even if it doesn't) you may want to test this PPA, which forces monitors to power on after making resolution changes: https://launchpad.net/~bryce/+archive/elderberry ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/762855 Title: [sandybridge-m-gt2+] Display on external monitor (vga) is black on 13 MacBook Pro 8,1 (x86_64) ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I experience the same problem in Ubuntu 10.10 (Maverick) and 11.04 Beta2 (Natty). I tried the nightly because it included fixes for the touchpad and sound. However, the display problem remained. I don't think it works in any very of Ubuntu to date.
