I'm using Ubuntu on my Dell XPS 17, connected to a Dell Dock via USB-C, that has 2 monitors connected with Displayport. Sometimes on signal acquisition, screens remain black, and I have to lock the session (Win + L), wait a few seconds, then wake up the laptop, so signal may or may not be correctly acquired (otherwise I'd do it again until it works)

On Windows, there's this shortcut, Win + Ctrl + Shift + B, that acts as if the screen were disconnected/reconnected. It may help with my signal acquisition problem. Is there an equivalent on Ubuntu/Linux, please ?

Unlike Lemmy, Mastodon doesn't have a "URL" field to share a link with preview in the post. Any URL shared is included in the post itself, greatly decreasing its visibility.

Is there a way to post from Mastodon that would set a link as previewed URL ?

Not sure who needs to read this, but if like me you're using Android Auto with your LineageOS/other libre OS smartphone, you probably need to go to Android Auto's development settings (click 10x on Android Auto's version number) > "Allow apps from unknown sources", so that apps from Aurora Store/F-Droid can connect correctly to Android Auto. I used to have "Media Unavailable" whenever I tried to play things on my car, and this fixed it.

What do you think of it ? https://neodb.social/discover/
