I'm pretty sure that what has changed is that the video connection for the X270 dock is standard DisplayPort, whereas the new T14/Lenovo dock combination uses USB-C alt mode to...

In your new setup, the T14 Docking Station communication is by a USB Type-C connector, operating in display port alt mode. I2C signalling is handled over the DP Aux channel....

I'm afraid you're hosed. Driver MST I2C support is problematic. In some configurations it works with no issues, in some configurations there are "phantom" displays that **ddcutil** can filter out,...

Yes, this warrants a bug report vs. amdgpu. The interrogate command pretty much has all the information needed, but the relevant parts need to extracted and collated for a coherent...

@digitaltrails I've added changes to branch 2.0.0-dev intended to avoid restoring stale cached display references. I was not able to replicate your problem of a display ref for a disabled...

It turns out that using slave address x13 as a proxy for whether the monitor is turned on does not always work. I have a monitor, (Samsung U32H750x) that reports...

Displays caching has been eliminated. Options ***--enable-displays-cache*** and ***--disable-displays-cache*** and command **discard displays cache** are no longer recognized. These changes have been applied to branch 2.0.0-dev. Thank you @digitaltrails for...

@digitaltrails **capabilities** is by far the most expensive **ddcutil** command, entailing multiple write/read requests associated sleep time, and possible retries. For any given monitor model, the capabilities string is constant,...

It's not clear if invalid data or no data is being returned from the monitor. Option ***--ddc*** should give more information. Using a large sleep-multiplier value is the first thing...

I think you're confusing glib with glibc. glib 2.40 was released in 2014. glib 2.40 glibc is currently under development.
