The mouse cursor disappears after a while. It happens randomly with any software (Chrome, Skype, terminal, LibreOffice etc...). The mouse still works though.It just the cursor which disappears.
I cannot find a pattern why it disappears or what makes it disappear. The only fix is to reboot (logout does not work). It works for a while after the reboot, then it disappears again. It only disappears when I move the mouse which makes me thing it could a be GPU driver bug (the screen is not redrawn correctly). I could be wrong obviously.

I've tried standard login and Wayland. It happens with both. I guess it's related to the hardware as I tried the same Ubuntu version on a different computer with an Intel GPU and it does not occur on it.

Only Ubuntu is installed on the drive (macOS is not). Ubuntu detects the GPU as Rv730.

Is there a way I can bring the cursor back without rebooting?

  • Is this a usb mouse? What happens when you disconnect & connect the usb port? What messages are logged in syslog? – FedKad Mar 13 '21 at 05:19
  • It's a wireless with USB dongle, but I also with 2 other USB wired mouses and it still happens.

  • If you unplug the usb mouse, wait a few seconds, and then plug it back in , does the cursor come back? – user10489 May 30 '21 at 16:54
  • It does not, the only solution is to reboot. I found a temporary workaround: Set SWCursor to on in Xorg.conf, but the cursor often blinks. – zetoune Jun 01 '21 at 13:34

Switching to a software mouse cursor fixed it for me. https://www.reddit.com/r/freebsd/comments/chjalp/xorg_cursor_disappeared/

Basically adding an xorg section for SWCursor:

create just a tiny file named something like 'swcursor.conf' under /etc/X11/xorg.conf.d/ containing the following:

    Section "Device"
       Identifier "device1"
       Option "SWcursor"
    EndSection

  • Yep, that's why I said in my previous comment :-). Thank you for sharing the whole xorg configuration. But in my case, it flickers too much. It's really annoying. – zetoune Sep 19 '21 at 16:38
  • @zetoune did you ever get a better solution? I have the same problem... – AndrewT Oct 12 '21 at 01:26
  • Adding this file did nothing for me. The cursor just seems to randomly disappear. I have noticed that if I make a Remmeina connection from my laptop, the system works in the Remmina window. – LarryM Nov 16 '21 at 20:03
  • This solution is not usable long term it looks awful – AndrewT Nov 16 '21 at 21:14
  • @AndrewT, nope. I did not. – zetoune Jan 10 '22 at 14:55
