In the round of testing I did before writing comment #4, I tried both with the dock and without the dock attached. I also tested with nothing plugged in at all aside from the direct HDMI connection.
If I can find a mini-DisplayPort cable I have some other hardware I can test as well to see if maybe it's HDMI or display specific. Is this the sort of thing we might be able to open a conversation to implement upstream? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2075983 Title: Strange behaviors with external displays over Displaylink Status in gnome-shell package in Ubuntu: New Bug description: Release: Ubuntu 24.04 LTS gnome-shell: Installed: 46.0-0ubuntu6~24.04.1 Expected behavior (As seen on Windows/macOS): * When plugging in external displays, they should be able to scale independently of the internal display * When external displays are active through a display link dock, closing the laptop lid should invoke suspend The above behavior would match the behavior seen when displays are connected directly to the laptop. Actual behavior: * External displays connected through a DisplayLink dock are forced to the same scaling ratio * Closing the laptop lid when external displays are connected through a display link dock results in the internal display turning off but no sleep behavior * This happens regardless of config changes with dconf, upower, or logind This is primarily a usability issue for laptops with limited ports for IO and extremely high resolution internal panels.
