FWIW, the upstream bug got migrated to https://gitlab.freedesktop.org/drm/intel/-/issues/37 but still no fix :(

Thomas,
Your report is very useful. I've been working on trying to better
handle the corner case where the pseudo-I2C bus for the laptop's display
claims to support DDC when it fact it doesn't.
Please run the following command and send me the output.
ddcutil environment --verbose
Are you installing ddcutil from git, the tarball, or one of the rpms or
dpkgs? I ask because it might be helpful if you could install a
development version of ddcutil.
Thanks,
Sanford

Hi
I built ddcutil 0.7.0 on Ubuntu 16.10. I have two external displays
connected to my Lenovo x260 via a Lenovo Ultra Dock. The displays are
Dell U2412Ms.
Here is the output of |ddcutil detect|:

However when I try and detect monitor capabilities it doesn't work:
***@***.***:~$ sudo ddcutil capabilities --display 1 Unable to get
capabilities for monitor on Display_Handle[i2c: fh=3, busno=3].

This seems like it may be related to issue number 8
<#8> - I'm not really all
that stressed about not getting this to work, but thought this might
be helpful.

I installed it from the tarball on the website. Happy to try a dev version if that would help.
Here's the output of sudo ddcutil environment --verbose

*** Primary Check 2: Check that /dev/i2c-* exist and writable ***
Checking /dev/i2c-* devices...
Unless the system is using the AMD proprietary driver fglrx, devices /dev/i2c-*
must exist and the logged on user must have read/write permission for those
devices (or at least those devices associated with monitors).
Typically, this access is enabled by:
- setting the group for /dev/i2c-* to i2c
- setting group RW permissions for /dev/i2c-*
- making the current user a member of group i2c
Alternatively, this could be enabled by just giving everyone RW permission
The following tests probe for these conditions.

from ddcutil.

Thomas,
Well, this is seriously weird.
First off, I'm going to ask you to send me the full, gory, diagnostics,
using command "sudo ddcutil interrogate". This will take a while to run.
Before I get into the weeds, a bit of background on how ddcutil
(currently) detects monitors on the I2C bus. It scans each of the
/dev/i2c-n devices, checking if slave addresses x50 (EDID) and x37 (DDC
communication) are active. If both are, it concludes it's found a monitor.
There are 2 things happening on your system. The first is indeed
related to issue #8 <#8>.
The driver is reports that x37 is active on bus /dev/i2c-3, which is the
laptop display. But in fact DDC communication fails (it's a laptop
display), which is why you get the errors on "ddcutil capabilities".
The current development tree performs an additional "sanity" test of DDC
communication before concluding it's found a DDC capable monitor.
The second thing that's going on with the external monitors is truly
weird. "ddcutil environment' probes the DDC environment in multiple
ways. The system command i2cdetect examines I2C buses, using
essentially the same algorithm as ddcutil. Like ddcutil, it finds that
/dev/i2c-3, 5, 6, and 7 have both slave address active. So these would
appear to be monitors. /dev/i3c-3 is the laptop display, which we know
about.
On the other hand, udev combined with xrandr reports displays on i2c-3
(eDP-1), i2c-4 (DP-1) and i2c-5 (DP2). Again, i2c-3 (eDP-1) is the
laptop display. So i2cdetect and udev are in disagreement, which hints
at the failures you're seeing. I suspect a video driver issue. This
will require some thought, and probably additional code to test your
environment further.
Are the external monitors connected to the dock individually, or are you
using DisplayPort chaining?
What happens if you use the DisplayPort connection on the laptop instead
of the dock?
Thanks for your help.

I'll answer the last questions first as this command dump is long.
- Monitors connected to the dock individually, one with display port the other with DVI.
- Don't know - laptop has mini display port. I think I've got one at home so I'll test that.
Here's the dump of sudo ddcutil interrogate - it segfaulted so let m eknow if you want me to run again.

*** Primary Check 2: Check that /dev/i2c-* exist and writable ***
Checking /dev/i2c-* devices...
Unless the system is using the AMD proprietary driver fglrx, devices /dev/i2c-*
must exist and the logged on user must have read/write permission for those
devices (or at least those devices associated with monitors).
Typically, this access is enabled by:
- setting the group for /dev/i2c-* to i2c
- setting group RW permissions for /dev/i2c-*
- making the current user a member of group i2c
Alternatively, this could be enabled by just giving everyone RW permission
The following tests probe for these conditions.

crw-rw---- 1 root i2c 89, 7 Jan 17 11:18 /dev/i2c-7
Current user: root (0)
Current user (root) has RW access to all /dev/i2c-* devices.
Checking for group i2c...
Group i2c exists
WARNING: Current user root is NOT a member of group i2c
Looking for udev nodes files that reference i2c:

*** Primary Check 3: Check that module i2c_dev is loaded ***
Checking for module i2c_dev...
Module i2c_dev is built into kernel
Remaining i2c_dev detail is purely informational.
Check that kernel module i2c_dev is being loaded by examining files where this would be specified...

*** Primary Check 4: Driver specific checks ***
Performing driver specific checks...
No driver specific checks apply.
*** Primary Check 5: Installed packages ***
ddcutil requiries package i2c-tools. Use both dpkg and rpm to look for it.
While we're at it, check for package libi2c-dev which is used for building
ddcutil.

Hi Thomas,
Thanks for the detailed output. It really does look like something odd
is going on with the I2C buses on the dock. I strongly suspect the
video driver which creates the I2C buses. It would be interesting to
see what happens when a monitor is plugged directly into the laptop,
both when it's docked and undocked. Another possibility, though not
likely, is the monitor. Some monitors are just ill-behaved. I have a
Dell P2411 that fails at DDC communication, and testing a second one
showed similar problems. So if you have a different model monitor that
you can easily plug in, that would be interesting to check as well.
The following commands would give me most of the information I need,
without running the full interrogate:
ddcutil detect --verbose
ddcutil environment --verbose
(Please send any extensive output as an attachment. It's easier for me
to work with.)
It would be interesting to see how other programs behave. The
simplest to try get-edid and parse-edid programs in package read-edid.
for i in {0..7}; do get-edid -b $i | parse-edid; done
If your laptop dual boots into Windows, there's are very helpful Windows
program for exercising DDC at http://entechtaiwan.com/lib/softmccs.shtm
I'll try adding some more diagnostics in the next point release, but I
suspect to really diagnose the issue I'll need to put my hands on a
similar system.
Thanks again for your help. I realize that I'm asking you to plug and
unplug equipment, which is inconvenient. Whatever you can do would be
useful.

home so I'll test that.
Here's the dump of |sudo ddcutil interrogate| - it segfaulted so let m

ddcutil version 0.7.1 has been released. There's a new option
--force-slave-address, which may address your problems of monitor
detection. I say "may" because I don't have a test environment that
exhibits the behavior you're seeing.
The segfault should also be fixed.
Please run the following commands and send me the output:
ddcutil detect --verbose --force-slave_address --stats
ddcutil environment --verbose --force-slave-address --stats
These commands will produce the subset of "ddcutil interrogate"
information that is relevant to monitor detection.
Please lease send the output as attachments. It's easier to work with.
Thanks,
Sanford

Thomas,
Thanks for taking the trouble to create the reports.
First, to state the obvious, --force-slave-address has no effect on your
situation. If the failure mode addressed by --force-slave-address had
occurred, there would have been traces in the logs.
The enhanced environment code in 0.7.2 is consistent with earlier
conjectures. The problem is most likely in one of these places:
- The intel video driver generally
- The dock hardware
- How the video driver handles the dock
- The monitor model
Interestingly, the (enhanced) environment log shows an errno status code
on /dev/i2c-5 never before seen: EREMOTEIO. This appears to be coming
from the i2c-over-aux code in the driver. (file gpu/drm/drm_dp_helper.c
or gpu/drm/drm_dp_mst_topology.c)
So I'm afraid all I can suggest is testing if hardware changes have any
effect:
- plug monitor directly into laptop
- try a different monitor
There's one other peculiarity I see in the logs, though I don't think
it's related to your problem. The monitor EDIDs for the U2142Ms read
directly by ddcutil over I2c do not quite match those reported by
xrandr. In particular, the former do not contain a string serial
number, the latter do. I have a few conjectures as to why this might be
the case, and have added code to the environment command that will be
included in the next point release.
Regards,
Sanford

I have a new Dell TB16 (thunderbolt) dock that seems to be interfering with DDC to my monitor as well.
I used to use a script with ddccontrol in it to change the brightness on my directly-connected monitor. With the dock in between, it no longer works. Read about ddcutil, then installed it, but it doesn't seem to be able to talk to it either through the dock.
ddcutil environment --verbose > ddc_environment.txt
ddcutil detect --verbose > ddc_detect.txt
Perhaps these can shed some light, however I suspect the problem is with the dock, firmware, or drivers themselves.

Thanks for the report. Yes, it does seem to be another case of I2C
passthrough on a dock not working. All the other reports have been for
Lenovo Thinkpad docks, so it looks like the problem is more general.
Common to all these cases is the i915 Intel video driver.
Looks like you're connecting the monitor to the dock via DisplayPort.
Have you tried DVI, HDMI, or (gasp) VGA? One person was able to work
around the problem by having both IIRC DisplayPort and VGA connections
to the monitor. He sets the monitor input to the DisplayPort
connection. Surprisingly, the monitor is nonetheless response to
I2C/DDC communication on the VGA connection.

The laptop has an HDMI port so I could use it, but I don't have a
cable handy, and not sure it supports 4k @ 60hz. Also, the reason
I bought this dock in the first place was to get rid of all these
cables crossing my desk, and replacing it with one. Connecting
directly defeats 50% of the reason for the purchase, sigh.

As as been discussed, there seems to be a pattern of I2C communication
failing with docking stations and the i915 driver. It's not
particularly useful for me to file a vague bug report with the i2c
folks, but if I can identify a pattern, .e.g. the problem is associated
with certain recent processors, that may be more useful. Please run
"ddcutil interrogate" as root and send me the output as a file.

Was that the whole output? The file ends abruptly at line 2338 in the
middle of a report. You might try sending it as an attachment.
Also, what is your processor. The video VID/PID is 8086/591B, which
appears to be in the Intel graphics range, but isn't in the PID
database, and I can't find the number anywhere online. Must be very new.

Can you send what was written to ddc_inter_? Where it ends would narrow
down where the fault is.
Even better, can you run it under valgrind? i.e. "valgrind ddcutil
interrogate"
Alternatively, "ddcutil interrogate" is essentially a combination of the
following commands. Which of the these fail? And where?
ddcutil detect --verbose
ddcutil environment --verbose
ddcutil usbenvironment --verbose
and, for each valid display number N:
ddcutil probe --display N probe
Thanks. I regard this as serious. Configuration issues go with the
territory for ddcutil. It's in the nature of I2C. But segfaults are my
doing.

Re the original problem before we got distracted by the segfault, here's
a (still incomplete)l exchange today with someone on the i915 team:
https://lists.freedesktop.org/archives/intel-gfx/2017-May/127424.html
Bottom line, the DDC/I2C failures when using a display connected to a
recent docking station appear to be in the DisplayPort driver code,
which affects the DVI and HDMI connectors, not just the DisplayPort
connector. Until that's fixed, there's not much ddcutil can do.
But here's the positive way to think about it. Your bug report helped
me see a pattern, which led to identifying a driver bug. So hopefully
this will get fixed, though it will be a while before the fix makes its
way into released code.

*** Primary Check 2: Check that /dev/i2c-* exist and writable ***
Current user: root (0)
Checking /dev/i2c-* devices...
Unless the system is using the AMD proprietary driver fglrx, devices /dev/i2c-*
must exist and the logged on user must have read/write permission for those
devices (or at least those devices associated with monitors).
Typically, this access is enabled by:
- setting the group for /dev/i2c-* to i2c
- setting group RW permissions for /dev/i2c-*
- making the current user a member of group i2c
Alternatively, this can be enabled by just giving everyone RW permission
The following tests probe for these conditions.
Checking for /dev/i2c-* devices...

*** Primary Check 2: Check that /dev/i2c-* exist and writable ***
Current user: root (0)
Checking /dev/i2c-* devices...
Unless the system is using the AMD proprietary driver fglrx, devices /dev/i2c-*
must exist and the logged on user must have read/write permission for those
devices (or at least those devices associated with monitors).
Typically, this access is enabled by:
- setting the group for /dev/i2c-* to i2c
- setting group RW permissions for /dev/i2c-*
- making the current user a member of group i2c
Alternatively, this can be enabled by just giving everyone RW permission
The following tests probe for these conditions.

Adding yourself to the CC list for the freedesktop.org bug is the most
useful thing to do in my estimation, as it indicates the significance of
the problem to the i915 driver developers.Β If and when they address the
problem, then it would be useful to build their latest driver and test
if it works.
β¦ I confirm plugging in the HDMI cable directly to the laptop works as
expected. The monitor is a Dell P2418D.

Unless the system is using the AMD proprietary driver fglrx, devices
/dev/i2c-* must exist and the logged on user must have read/write
permission for those devices (or at least those devices associated
with monitors). Typically, this access is enabled by: - setting the
group for /dev/i2c-* to i2c - setting group RW permissions for
/dev/i2c-* - making the current user a member of group i2c

permission The following tests probe for these conditions. Checking

For what it's worth, I have 2 DP Dell U2717D monitors via the lenovo ultra dock, and a x270, and they work great. Unfortunately, ddcutil loses it's ability to control brightness when connected directly to 1 monitor, as per this description.
Seems like the gory thread was useful at the least for pinpointing the actual cause.
Very keen to assist in testing or other such things to solve for the docking peeps.
Will at least add myself to their bug cc on issue.

@mattcph I saw your comment on the freedesktop.org bug, you say you filed a bug with lenovo, is it public? Any link to this report?

@mattcph Can you perhaps test if some Windows alternatives to ddcutil work through the Ultra Dock? A quick google gave me https://www.clickmonitorddc.bplaced.net/, I haven't tried it myself (not a Windows user), so no guarantees, but I think it might work.

I have an Dell TB16 connected to a XPS 9560. Monitor is connected via DP to the dock.
On Windows I tried multiple DDC utils like clickmonitorddc and they all work just fine.
On Linux ddcutils & ddccontrol both work only if monitors are directly connected to the laptop.
So at least for my specific setup I can say that this is a non-issue when using Windows.

Same here, Dell set up, I get around the problem (literally) by having a second cable from my laptop to the monitor. :-/
Kinda defeats the purpose of the docking station but I use it for other things as well.

This should help, said to be in Linux kernel 5.10, in distros in 2021:

I have checked. The changes are in the just released 5.10 kernel.
@frogmaster has previously (issue #11) reported success having built his own driver with the changes. Further comments should be added to that issue.

I've tested this on 5.10.1 and it works fine, the only interesting thing is, my monitor shows up twice now:

First, thank you @thmcmahon for reporting the success with the 5.10 kernel. Many people are interested in this problem.
Multiple /dev/i2c devices for the same monitor is a known problem. See, the FAQ. Clearly a driver problem, and I've been adding more and more code to the environment command to analyse this situation. Can I ask you to run ddcutil environment --verbose as root and submit the output as an attachment?
I've created a new issue, #160, specifically for this problem. Let's continue the discussion there.

A Christmas miracle! I had already stopped hoping that this would work someday.
So, YES, I can confirm it to be working too (kernel v 5.10.4) on a Lenovo ThinkPad Thunderbolt 3 Dock Gen 2.
What a nice surprise! What a relieve!
