XPS 13 9300 and WD19TB linux problem

Thanks @emapex for answer !

I think my two problems are solved since I upgrade my Linux Kernel to the latest version :

5.11.3-051103-generic

If any of you have still some stability problem, try to update your Kernel
For now, I had no blink screen and, when I power up the laptop with lid close by pressing Dock button, all works perfectly.

I hope this will continue like this !

Hi,

I am following up to check if the issue has been resolved with the help out the steps shared by the community users.

Hi Geofrey, I can reboot the system and have it return to the same state (laptop to the right of the external display).  However suspend is a mess -- it takes some fiddling with the "Display" GUI to get to the previous settings as it usually comes up in "mirror" mode.  I am still running "5.8.0-44-generic #50~20.04.1-Ubuntu"; a newer kernel might be the answer as is mentioned elsewhere in this thread.  -- John

Hi,

I have replied to you from a private message.

Good.  Just tried a new kernel.  So far Kernel 5.10.21 appears to work correctly with XPS 13 9300 and WD19TB with one DP display.

https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.21/

Put these four files in a new directory and "cd" into it:

linux-headers-5.10.21-051021_5.10.21-051021.202103070732_all.deb
linux-headers-5.10.21-051021-generic_5.10.21-051021.202103070732_amd64.deb
linux-image-unsigned-5.10.21-051021-generic_5.10.21-051021.202103070732_amd64.deb
linux-modules-5.10.21-051021-generic_5.10.21-051021.202103070732_amd64.deb

sudo dpkg --install *.deb

sudo reboot

Besides rebooting to the correct display arrangement, "suspend" now works right.

Using the mentioned method - I can confirm I'm problem-free in the last three days!

@orduek, note there is no "kernel 5.10". The DP MST bug which causes WD19TB dock dropouts was fixed in 5.10.16 onwards (and all 5.11.* etc). The bug still exists in all 5.10.1 to 5.10.15.

Yes, I meant 5.10.XX - but thank you for the clarification.

I updated the firmware on my XPS and the WD19TB dock to the recently released versions (1.5.0 and 01.00.15.01), then got onto a 5.10 kernel as follows:

sudo apt install linux-oem-20.04-edge

If you had previously installed an HWE (hardware enablement) kernel, be sure to remove it so that the 5.10 kernel is the first listed when running sudo update-grub.

The dock now seems to be working correctly so far.  I'll post an update if it starts having problems again.

Newer kernels doesn't seem to fix double monitors attached to dock by the way.

Weird thing is, If I run following script after plugging the dock, it seems to work:

xrandr --output eDP-1 --off --output DP-1 --off --output DP-2 --off --output DP-3 --off --output DP-4 --off --output DP-3-1 --off --output DP-3-2 --mode 1920x1200 --pos 0x0 --rotate normal --output DP-3-3 --primary --mode 1920x1200 --pos 1920x0 --rotate normal --output DP-1-1 --off --output DP-1-2 --off --output DP-1-3 --off

Which is extracted from "arandr" tool.

But when I set up autorandr to take care automatically, system shows both external monitors are in use, but there is no signal going on (except for a 1/10th of a second, the monitor led's are flashing and closing again).

I have 2 dell monitors (connects 1 via displayport, 1 via HDMI), WD19DC dock and XPS 13 9310 2-in-1. That is so frustrating, considering "everything else" works flawlessly.

This turns out because of 2 xrandr commands are being applied while using autorandr. Trying an experimental branch to give single xrandr command worked.

I still have no idea what is wrong with this dock, but looks like a workaround which developers can check and find the actual problem.

I've written extensively here and elsewhere about the problems I have had with my XPS 13 and Dell WD19TB dock since I purchased it in June 2020 but I have to note that since recent BIOS 1.5.0 + Dock firmware 01.00.15.01, and using a Linux kernel 5.10.16 or greater, that all problems appear to have been fixed. Yay, we finally got there!

Hi,

I had a very similar problem but my setup is Arch Linux + Dell XPS 15 7590 + WD19TB and I have not had any problem with the display but the USB-connected keyboard and mouse flickered (the LEDs of the keyboard) with a message (checking with dmesg) similar to:

usb 1-1.3: reset high-speed USB device number 3 using xhci-hcd

especially this was provoked if I played any sound on my Dell AC511 Sound Bar connected to the WD19TB. Then it went mad flashing the keyboard and spewed out heaps of the above statements in the dmesg log. It happened otherwise too but not as frequent.

In order to get the mouse working again I had to disconnect and re-connect. Just so super-annoying.

Now, I have found what seems to actually have fixed it in a Ubuntu forum and that is (besides having the latest BIOS for the computer and firmware for the WD19TB) to disable "C-states" in the BIOS of the XPS 15. The is checkbox for that in the BIOS settings. After disabling it I have not faced any problems and the computer doesn't really seem to run much hotter either.

We bought a no-name usb-c dock from amazon. Never had any problem since. The Dell WD19TB is just broken with linux.

The no-name usb-c dock works out of the box without any custom installed kernels. And costs only 1/3 of the WD19TB. I think we will just sell those on ebay. Maybe someone else has the nerve to tinker with that.
