Two days ago I installed elementary OS and now I am experiencing issues with my external monitor. I'm using a Dell XPS 15 9560 with and LG superwide monitor.
Unable to disable built-in monitor
At the office I like to work on a external monitor with the laptop open and the built-in display disabled. With this setup I can use the track pad of the laptop for scrolling. That's how I did it with the previous distro (Pop!_OS) I've been using. But disabling the built-in monitor seems to be impossible with eOS, or am I wrong?
No tray nor dock after sleep
While using an external monitor, my laptop is closed. This works fine s long as the system does not go to sleep. Waking it up is a pain because it does not listen to the wireless mouse or keyboard (also Dell). Touching the built-in keyboard wakes up the system but then I have two screens, both missing the to menu bar/tray as well as the dock. The only thing I can do in this scenario is a hard reboot.
Not dock nor tray after reboot
This morning I logged in and again, no tray or dock were showing, so I did a reboot without the external monitor. But even after a reboot, they didn't show up. I had to manually launch the switchbaord (
/usr/bin/io.elementray.switchboard) though the terminal to be able to access display settings, where I fiddled a bit with the settings. After rebooting the tray and dock were back (fortunately).
