[dp] External Screen doesn't wake up from sleep

[omriasta]

I have a Lenovo X1 Carbon with an external screen connected to a Mini DP to VGA adapter. External screen works fine until the display goes to sleep for inactivity (just the display goes to sleep, not the laptop).
When I return to the laptop, the built in screen wakes but the external screen does not. The screen is still detected, xrandr displays the resolution and I can move the cursor to the external display but the display remains off.
I have tried cycling with Fn+F7 and also tried Ctrl+Alt+F1 then Ctrl+Alt+F7. The only way to get the external display back on is by disconnecting the adapter from the laptops DP port and reconnecting.

dmesg produces:
drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting

[Chris Wilson (ickle)]

It is suspicious that it would only appear to fail whilst the monitor is off - that suggests we are missing a required wait for one of the control lines to power up.

Can you please 'echo 6 > /sys/modules/drm/parameters/debug' then xset dpms force off, wake it up (hopefully reproducing the issue) and then attach the output of dmesg?

[omriasta (omriasta)]

file was in /sys/module/drm/parameters/debug (instead of modules).
Attached is dmesg

[Robert Navarro (crshman)]

I'm having a similar issue...I believe....my monitor goes blank after a certain time and doesn't turn back on....I looked up the error "drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting" and that brough me here....I've attached my dmesg output.....that output is *after* I turn the monitor back on from a dead state.

As far as I can tell no output is generated right before the blanking of the monitor.

Still present after updating to 13.10

Issue is definitely related to DPMS. Disabling DPMS altogether prevents the screen from turning off completely in turn preventing it from failing to turn back on. Screen still blanks when I lock the screen but backlight remains on and the screen doesn't go to "power saving" mode.
I have updated to the latest kernel from drm-intel-next (found here: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/) and the issue still exists in 3.12.0-997.
It seems this issue has also been noted on the Pixel here: https://code.google.com/p/chromium/issues/detail?id=257457
On the new Kernel I installed the Error is slightly different. dmesg shows:

[penalvch (penalvch)]

omriasta, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc7

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

This issue is NOT resolved yet.

[omriasta (omriasta)]

Bios Updated to 2.61 issue still exists. I was on a 3.12 upstream kernel and the issue persists.

[omriasta (omriasta)]

Just purchased a Startech.com mini dp to DVI adapter and the issue does not occur.
It seems that the issue is confined to the mini dp to VGA adapter. If anyone is looking to purchase one of these the Cirago "active" mini dp to VGA has issues on Ubuntu when the screen goes to DPMS.

[Mike Harris (t-mike-6)]

This issue affects me as well. Lenovo T460 and a Lenovo basic docking station. The docking station is connected to an Acer 24" monitor via VGA. Once the desktop locks and the unity login appears the external display enters power save mode. Unlocking via the password does not power up the external display (all windows are moved to laptop display). I have to eject the laptop from the dock, wait a couple of seconds, then put the laptop back in the dock for the external display to power back up. I'd prefer not to physically undock/dock the laptop several times a day.

[penalvch (penalvch)]

Mike Harris, it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.
