[KVM] no mouse cursor in noVNC console

First post on this forum . I spent days migrating from a Synology Diskstation to OMV, including lots of docker containers. Most configuration topics went smooth, some needed a certain amount of troubleshooting as is expected with such a migration

There's one (relatively futile...) configuration item left that I can't figure out. When running an Ubuntu 22.04 VM using the KVM plugin, there is no mouse cursor in the noVNC console. The mouse only works when guessing where about the cursor is on the screen. Using the spice-html5 console the cursor is working, but I find spice unusable slow...

When searching I found some tips in old topics about changing the number of CPU cores, this makes no change. Also Ubuntu 20.04 is showing this behavior.

Anybody has a clue how to fix this?

I wasn't aware that the noVNC use case was the OS install. I like the responsiveness (and it to work out of the box).

Indeed in that case I'll go for a solution like xrdp.

All clear about your recommendation

In the meantime I have found a workaround that works. Setting the cursor size in the Ubuntu accessibility settings to the biggest cursor works! This shows the huge cursor in noVNC without any issues. I found this fix in a relatively old topic related to a similar issue.

In the meantime I'll test some permanent fixes like xrdp and a real VNC client.
