Screens stopped working through dock station

zw flag

I have an Ubuntu 20.04 on a Dell laptop with a Targus dock station (model 412). I have the dock station connected to the laptop through usb-c, and one HDMI and one VGA connected to the dock. It was working properly (for 2 years) and this morning it has suddenly stopped working. If I plug USB devices to the dock station they work properly.

I have tried unplugging all the connectors but everything looks fine. If I connect the HDMI screen directly to the laptop it works properly.

Any advice for a more thorough check?

Thank you.

The dock is burned out?

I don't think so, usb ports work properly

Just because one part works does not mean another part is not burned out.

An [ammeter](https://en.wikipedia.org/wiki/Ammeter) is used to measure electrical current. It might help diagnose a hardware fault if you know what you are looking for but I'd suspect a software issue, tbh.

dmesg can be used to examine the kernel logs for error messages related to drivers... This might help you.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
