Still kernel traces on 1.1.61

[displaylink-mlukaszek]

What is your graphics environment and when does it happen exactly? It looks like something is querying the connector state constantly, so EDIDs from both monitors are read in a loop - EVDI logging level is "debug" by default, so it prints it out. Is this with some sort of Display Settings window opened only?

[daugustin]

The kernel traces are from uptime 18s, so this happenes at boot with no userspace tools interacting yet, maybe when the displaylink userspace component is starting.

The output from 75s is probably when I used xrandr to activat the screens.

The notebook has dual Intel/Nvidia graphics, altough the nvidia is disabled and everything runs on the Intel chip:

00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06)

This is probably an Intel HD 530.

I've this problem, too. Just on boot. If I connect the dock later on, there's no stacktrace. Single Intel graphics here. Let me know if I can provide more information.

[displaylink-mlukaszek]

We are aware of the initial 3 backtraces with evdi_dumb_create, but we never saw any consequences of this - so it's been a low priority to look at so far. Is this actually causing any problems?

[cajus]

For me there's a black secondary screen in this case. If I do not reboot, the secondary screen gets activated (black), and the primary display has just approx. 200px wide display on the left. The remaining part is black.

I've to reboot with the D3100 initially unplugged to make it work.

I'm seeing the same issue (see also #20) on Fedora 23. Doesn't seem to cause any real trouble so far but the mouse cursor on my laptop screen is blinking. On the displaylink attached screens it's fine.

[cajus]

Just a flickering mouse cursor? Doh. I've two mouse cursors. One is static, the other one is flickering ;-) While the DisplayLinkManager has a high load. See: http://displaylink.org/forum/showthread.php?t=64039

Attached a core dump there. Hopefully someone will take a look at it.

[daugustin]

Yes I can also confirm the flickering mouse.

[cajus]

With the Dell USB-C connector, I'm getting a black screen on the internal and the external monitor when I attach a screen to it and these (different) Stacktraces are generated.

[displaylink-mlukaszek]

@cajus this above looks more like a problem in intel's driver to me. Note the output names above.

[cajus]

Yes. Since I don't know what the DLManager is doing - or even how this is meant to work, the problem looks at least related to the usage of a DL device. The stacktrace only pops up when I connect the DL device. I never had any issues with the intel drivers on this notebook.

[hadess]

The one just above is a problem with the Intel driver, but the original error still happens inside evdi, on Fedora 24 this time, with the 1.1.65 version of evdi and libevdi.so, and 1.1.62 DisplayLinkManager:

[abrudin]

I have a similar stacktrace as the original poster on a Dell XPS 13 (2016) running Ubuntu 16.04 with what I believe is the latest DisplayLink (1.1.62?). For me my primary screen is 3/4 black and I have to go in and "apply" the current display settings to fix the problem (which only appears with the Dell USB-c -> Displaylink adapter plugged in).

[Blackburn29]

I was able to resolve this issue by blacklisting udl and udlfb, uninstalling the driver, reboot,ing and re-installing.

Xubuntu 14.04 LTS - i3 - Compton

I cutted some non-related logs in the middle.
My issue is: the monitor goes black after a couple of minutes and even when it is working, it is laggy. I'm on a J1900 cpu, the DisplayManagerlink is using the 100% of one cpu core...

(Ubuntu 16.04)

Traces should be fixed by 03e9760.

[wpoely86]

After two days on 1.2.55 I still haven't seen the traces again. So indeed fixed.

[displaylink-mlukaszek]

Thanks for confirming. Closing.
