WD19TB: Screens randomly going to Standby / Slow flickering / Freezes

I am using a Dell WD19TB Dock to connect my Dell XPS 13 2-in-1 7390 to two 1440p Monitors via DP (Not daisy-chained), Network and the occasional thumb drive.
Kernel: 5.6.11-arch1-1
Desktop Environment: KDE plasma 5.18.5-1 with X 1.20.8-2
xf86-video-intel is not installed

I am running out of Ideas with this one: Randomly, the screens connected to the dock:
+ Go black for a few seconds, then come back up again as if nothing happened
+ Sometimes randomly go into power saver mode (Screen OSD tells me so) until:
  + I unplug the USB-C wait for all of my windows and panels to be moved to the laptop screen and then re-plug the dock.
  + I re-plug the monitors from the Dock. (I have to re-plug them both individually)
  + I Reboot.
  + I power cycle the dock.
  + I disable and re-enable the screens using xrandr <- This appears most noteworthy to me!
 

 xrandr --output DP-3-1 --off && xrandr --output DP-3-1 --auto 

   
+ The screens always sleep when waking up from hibernate. (Suspend to Disk)

Whenever they go into power saver mode, they are acting like they are not receiving any signal, where as X is acting like they are there and doing their thing. (I can blindly move my cursor accross these screens and grab windows from them to my laptop screen.) The Laptops built-in-screen is not affected in any way!

What I tried:
+ (Re-)trusting the Dock using boltctl and the settings panel
+ Some posts around the web suggest turning off thunderbolt security, but it seems like this notebooks firmware settings do not offer me such a configuration. I can only turn thunderbolt on or off. Heck even if it where there, its not an acceptable solution.
+ Some posts revolving around the TB16 dock suggested firmware updates. I could not find any such updates for the WD19TB on Dells Website.
+ Running

xrandr --output DVI-I-2-2 --auto

was suggested to bring the screens back up, not a shrug.
+ Disabling DPMS did nothing.
+ Running

xset dpms force on

was not able to wake the screens up, only aforementioned re-enabling via xrandr.

Observations:
Usually when I am not experiencing the screen dropouts, the power-led on the dock is off, while all the connections with it work fine (DP, USB, Network, Audio devices are also shown). The power LED even stays off when power cycling the dock.

The monitors going to power saver or flickering does not produce any output in dmesg, nor changes in lsusb or lspci. However, here are the outputs:

Any help is highly appreciated. If deemed appropriate by someone more experienced with the community, I would like to contribute an article on this dock to the wiki.

Re: WD19TB: Screens randomly going to Standby / Slow flickering / Freezes

After further observation it seems like the screens going blank often comes with this dmesg output:

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun

Google is offering me this among others:

https://bugzilla.redhat.com/show_bug.cgi?id=1506339 Seems like these guys' issues also correlated with external monitors being plugged in. Its old but there are quite recent complaints in the comments.

Re: WD19TB: Screens randomly going to Standby / Slow flickering / Freezes

Hmm, I kind of ignored that because my primary concern was the screens not coming on any more, which seemed different to flickering to me. (Its not like my screens go disco-mode. They blink once and then they either come back or stay off.) But since one of the bug descriptions also mentions the underrun, I will give it a shot and report back. Thanks!

Re: WD19TB: Screens randomly going to Standby / Slow flickering / Freezes

I enabled to kernel setting and rebooted. It worked fine for half a day. Then everything went broken again. Screens dropped out, my re-enable procedure via xrandr only kept them awake for a few seconds.
Then, when first trying to write this post, screen and audio froze entirely. I had to long press the power button. Only thing logged from that moment is again:

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun

Next thing I will test is whether using specific applications or intermittent hibernations is provoking the issue.

https://wiki.archlinux.org/index.php/In … ete_freeze would fit a complete freeze better and maybe relate to your hibernation hunch.

Re: WD19TB: Screens randomly going to Standby / Slow flickering / Freezes

My CPU is an Icelake but I will give it a try regardless, thank you!
It might actually tie in with my observations over the last two days: I did not use hibernate and the issue only occurred after performing "reboots". Once they occurred after rebooting I was able to stabilize by doing a proper cold-boot reboot. My hunch here is that a reboot causes different C-State transitions than a proper cold boot? Can someone offer expertise?

Re: WD19TB: Screens randomly going to Standby / Slow flickering / Freezes

EDIT: Nevermind, changing Thunderbolt BIOS settings has no effect. Just had another blackout.

All I can say is that I have the same laptop and dock, and exactly the same issues over multiple kernel versions. Windows on the same device works fine.
