I have a multi-monitor setup. I am using the iPad as another screen. I followed these instructions: https://www.omgubuntu.co.uk/2022/06/use-ipad-as-second-monitor-ubuntu-22-04

It is usable but, the mouse pointer (using desktop mouse) does not appear in 'extend' mode. The mouse traverses multiple monitors and, in the iPad, I can see hover animations but, the cursor itself is not rendering.

On iPad, using the Microsoft Remote Desktop app. I am using Ubuntu 23.10 with Wayland (does not work in X11). The mouse pointer does not appear on the iPad. I can use the iPad mouse pointer and, it response naturally to touch events in touch mode (the caveats in the article are out-of-date) but, the remote cursor (desktop mouse pointer) does not appear. Some remote desktop software has showing or hiding the cursor as a feature.

If you know how to fix, if it is a simple setting, please let me know.

According to this thread the developers never intended for these virtual monitors to be used in extend mode. The intention was only to enable you to remote-desktop in when the machine did not have a monitor (ie. headless setups).

When you remote-desktop into a machine, the mouse cursor is not part of the screen. It is displayed on the client, and is controlled by the mouse on the machine that is viewing it. This makes sense, because you want mouse pointer movements to be instant.

Because of concerns about the potential for lag of pointer updates while showing video, and the need to add a separate setting to tell it to do so, the developers will not implement the code to show the cursor.

  • For a Microsoft product, that makes sense. However, the competition, TeamViewer, does have "Show Remote cursor" option, despite the "lag" which is minimal on a local area network (which is an option for TeamViewer). However, heavy usage of TeamViewer is not free. RDP is free but is missing the "show remote cursor" option. FYI: I have used Synergy in the past to use the same mouse and keyboard between computers (and share clipboards). The lag is virtually non-existent on LAN. – sheldonm301 May 15 '24 at 23:32
