NVIDIA Proprietary Driver supports KMS now - can the DisplayLink driver support it?

What's the output of `xrandr` after doing the above? Do you see a DVI-*-* connector, if yes, does it look connected or not? Does `xrandr --auto` trigger any change?

Cheers,

Do you see a DVI-*-* connector, if yes, does it look connected or not?

"xrandr" does not report any "DVI-" text.

Does `xrandr --auto` trigger any change?

Unfortunately not.

Any further ideas? It would be a real improvement, if the "official" driver from Nvidia would be supported.

I don't see any connector that would be related to evdi; so I'm curious what would it log from the machine boot, with verbose logging on. (try passing "initial_loglevel=6" via /etc/modprobe.d/evdi.conf)

/etc/modprobe.d/evdi.conf

There is no such file on my system.

I have tried to edit it via

sudo vim /etc/modprobe.d/evdi.conf

I am using Ubuntu 16.10. What shall I need to do then, to extend the logging information for you?

Which log-file will you need then? I suppose you want me to switch the log-setting, reboot and afterwards post you the log file in this forum-thread.

[mlukaszek]

Yes, you need to create file and pass an option you'd like to use while loading evdi - see https://wiki.archlinux.org/index.php...Fmodprobe.d.2F

The contents of the file should be: options evdi initial_loglevel=6

After rebooting, evdi should be much more chatty in your dmesg log. Providing dmesg log and X logs would hopefully show something interesting.

Michal

I have created the file and added the desired content. After the reboot, I have created an archive with log files by the "DisplayLink Linux Support Tool (1.2.17)" (http://www.displaylink.com/downloads/file?d=68). This zip-archive is attached to my post. Please be so kind and take a look, if my system provides any useful information.

[mlukaszek]

I don't see evdi being loaded or even attempts to load it, also DisplayLink Manager is not running. Is the driver installed at all?

Cheers,
Michal
