[Regression] Thinkpad dock: External monitors not recognized after 15.04 upgrade

[aexl]

External monitors are not recognized in display settings when plugged into any dock port.

They *are* recognized after a reboot (not after logout).
After plugging out and the in again they are not recognized.

A monitor plugged in and out of the non-dock VGA is recognized instantly.
After plugging in or out of the non-dock VGA, monitors plugged to dock ports are recognized (which serves as a crazy workaround for me now)
(update: this works sometimes, sometimes not).

Everything used to work with 14.10, but stopped with 15.04.

A recent test with 1510 live CD did not fix this.

Updated summary with new findings.

[penalvch (penalvch)]

aexl, thank you for reporting this and helping make Ubuntu better.

Could you please run the following command once from a terminal as it will automatically gather and attach updated debug information to this report:
apport-collect -p xorg 1530171

Please ensure you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

When reporting xorg related bugs in the future, please do so via the above method. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Thanks christopher, i'll go on like this!

[aexl (aexl)]

Thank you christopher for this reminder, i did not knw that BIOS had to be updated.

Unfortunately the BIOS update did not change anything.

(Note: On the linked page the current BIOS is labeled 1.82, but the bootable ISO as well as its README (and the readme of the windows BIOS updater) announce 1.81, as does my updated BIOS. So Lenovo seems to have it got wrong. See https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/j4uj65wd.txt )

xl@thinker:~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
[sudo] password for xl:
J4ET81WW(1.81)
08/14/2015

Note to the above apport data:
I did the aport twice.
The first config was WITH 2 external monitors over the dock.
The second WITHOUT these monitors.
Guessing this might help.

(but some stuff may be broken as i had a strange 503 exception on the command line, containing:
    At least 4 queries/external actions issued in 0.06 seconds OOPS-4ade3bac7cd0be6540a006ad87bf530b
)

[penalvch (penalvch)]

aexl, if you boot with a kernel from 14.10 (3.16.x), does the issue go away?

[aexl (aexl)]

YES, booting with 3.16.44 makes this go away.
Every plugging in and out of monitors (or (un)connecting the dock) is reflected instantly by display settings.

[penalvch (penalvch)]

aexl, at your earliest convenience, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

[aexl (aexl)]

Yes this is fixed upstream, Yay!

Given that vivid is end of life, i think you can close this, but leave it up to you.
In any case: Thanks for guiding me through this!

[penalvch (penalvch)]

aexl, while Vivid is EOL as per https://wiki.ubuntu.com/Releases, the release you would be upgrading to isn't.

Hence, to see if this is already resolved in Ubuntu, could you please upgrade to either Wily or Xenial, and advise if this is still reproducible?

[Robert Schetterer (rschetterer)]

I am tested wily ,xenial, kubuntu, kernels 4.2 , 4.4 on brand new thinkpad t450s with thinkpad pro dock 90w.
The laptop and the dock has latest fimware !
Intel graphics driver is at latest state too.
Also tested latest 4.5 drm intel nightly. All external displays work always when directly attached to the laptop.
But with laptop docked, external displays are only running after boot, but fail when wake up from sleep mode configured in kde
closing lid. This is a very common user powersetting an is awaited to work. Most of the times external displays could reconfigured i.e by script produced from arandr ( gtk gui wrapper for xrandr ). But a universal script workaround seems complicated with acpi, systemd in userland for all thinkable combinations of possible displays ( up to three include lcd on laptop are possible).

It should simply work out of the box.

Additional info i invested a lot of time in kernel logs and trying grub start parameter, cause there were other ugly bug with intel 915 driver ( pci lied SDE etc fixed in 4.5 ) , there is also a point in the bios configure 10s to wait for notice external displays. Also 2014 the dock had a bug ( also on windows with external displays which was fixed by new firmware ).
It seems simply the dock does not pass external displays connected after laptop and external displays got sleep mode after wake up, prove is made by plug/unplugging external display and reenable it in kde. Also open windows were only reconstructed
after awake with kernel 4.4 /4.5 after manual reenable, with kernel 4.2 most of the time also plasma crashes and simply undock
crash x-server too. Any idea what to look next ?
Regards

[penalvch (penalvch)]

Robert Schetterer, 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.

For more on why this is helpful, please see https://wiki.ubuntu.com/ReportingBugs.

[Robert Schetterer (rschetterer)]

i vote this as a bug from the dock ,you may contact lenovo developers for more info to fix
i wrote a blog to workaround with systemd xrandr see
https://sys4.de/de/blog/2016/03/09/external-displays-thinkpad-pro-dock-90w-stay-switched-after-resume/
perhaps someone will find a better way with xranrdr and systemd more dynamical and no additional needs for insert username etc
