external monitor turns off
1 Attachment(s)

I am using Ubuntu 16.04 on Dell Latitude. The DisplayLink docking station seems to work perfectly at first sight but then the external monitor turns off after a random time interval (this can be seconds or even an hour).

I attach the output of the DLSupportTool.

I would be very glad if someone could help me.

Kind regards,

Can you check if disabling USB autosuspend helps?

thank you for your prompt response.

According to the instructions, I created the file `/etc/default/tlp` and inserted there `USB_AUTOSUSPEND=0`. I also created the file `/etc/udev/rules.d/01-usb-dock.rules` and copied the corresponding text.

After rebooting, the problem is unfortunately not solved.

Do you have maybe other ideas?
