4 years ago To clarify, there's no database that ddcutil consults to activate a monitor. It "simply" attempts to communicate with the monitor's Virtual Control Panel (VCP) using DDC/CI. It interprets VCP features (e.g. that feature x10 is brightness) per the definitions in the Monitor Command Control Set (MCCS) specification.
What you've got is a marginal DDC/CI implementation in the monitor/video driver combination. Sometimes it works, sometimes it doesn't . DDC/CI is an inherently unreliable protocol (think UDP). The client, ddcutil in this case, is responsible for retrying failed operations. With most monitors, retries are seldom needed. If you look at the statistics sections of the interrogate output, you'll see that operations commonly require multiple retries to succeed, and even then often do not.
Why do things work on Windows but not Linux? (And I take "In Windows this worked most of the time" to indicate that it does not always work even in Windows.) First, I suspect the Windows drivers are just better at handling marginal monitors. It may be that Windows drivers slow down the I2C bus speed when errors are encountered. LInux drivers do not. Second, I doubt that monitor manufacturers test on Linux.
Of note, despite being a recent model, the monitor reports its MCCS version as 2.0. That is very old. The most recent version (for many years now) is 2.2. That suggests that the monitor may be using an old DDC/CI implementation as well.
Things to try:
Use the --sleep-multiplier option, (e.g. --sleep-multiplier 3) to increase the time that ddcutil waits, as per the DDC/CI spec, between sending a request to the monitor and reading the response. The delay is intended to give the monitor time to process the request.
If you have another monitor available, try connecting that one instead. Does it have similar problems?
The interrogate output shows that the monitor is connected to the on chip video implementation, which uses the i915 driver. What happens when you switch the monitor to the discrete Nvidia chip, which currently uses the Nvidia proprietary driver? If you try that, be sure to use the Spedial Nvidia Driver Settings http://www.ddcutil.com/nvidia/. You might also try using the open source nouveau driver instead of the proprietary Nvidia driver.
Good luck and let me know your results.

Hey,
So I just switched to Linux and all bar one thing is working fine: DDC/CI.
Monitor: Samsung CF390 (FYI this is attacked by HDMI to my laptop)
In Windows this worked most of the time, had to turn the monitor off and on occasionally to refresh it. But with softMCCS (A windows app) and a DDC/CI app I was able to control the backlight and colour tinting.
However in Linux, ddcutil says the monitor is in the database but DDC/CI is not active. While I agree it's not active, it should be possible to activate it. And in Linux I don't know what I'm doing with this one. Hope you can help. From what little I've managed to follow here's some output.

Great start, eh?

If there's anything else you need to help you, let me know. I'm moving house tomorrow but from Wednesday I should be able to reply again, if our ISP does its job.
Thanks in advance.

FibroJedi Samsung CF390 Monitor Interrogate Output.txt Hey,
So I just switched to Linux and all bar one thing is working fine: DDC/CI.
Monitor: Samsung CF390 (FYI this is attacked by HDMI to my laptop)
In Windows this worked most of the time, had to turn the monitor off and on occasionally to refresh it. But with softMCCS (A windows app) and a DDC/CI app I was able to control the backlight and colour tinting.
However in Linux, ddcutil says the monitor is in the database but DDC/CI is not active. While I agree it's not active, it should be possible to activate it. And in Linux I don't know what I'm doing with this one. Hope you can help. From what little I've managed to follow here's some output.
Great start, eh?
$ ddcutil getvcp known --bus 6Most of this returned "Invalid Response"ddcutil interrogate 2>&1Attached as a txt file. (Edited as I found how to upload attachments) If there's anything else you need to help you, let me know. I'm moving house tomorrow but from Wednesday I should be able to reply again, if our ISP does its job.Thanks in advance.
