Mouse doesn't show up when using novnc

Open mew1033 opened this issue 5 years ago • 12 comments

When I use the allinone container and connect to the novnc port, I can use ozw-admin, but I can't see the cursor at all. If I can figure out where I am, things work alright, but it's very difficult to use. No mouse

This seems to be a issue with some combinations of Browsers and NoVNC. I've tried to force it to update the Cursor on start - Can you try our the allinone-21 when it appears in a hour or so?

Can do. I still don't see a build 21 though. Looking here: https://hub.docker.com/r/openzwave/ozwdaemon/tags

+1. Same issue. However, it seems if I have quickly previously had a real vnc connection and then go to browser it sometimes does work.

Sorry - Please try build 23. Not sure what happened to 21

Just tried it, doesn't look like it helped.

This is probably (?) a bug in the QT vnc plugin and how it enables (or doesn't enable) the cursor. Not sure if there's a solution there. QT vnc doesn't seem to an important component. There is not even any official documentation.

Debian ships an out of date version of NoVNC. In the latest release, v1.1.0 (released over a year ago), there is an option in the client to show a dot when no cursor is enabled. This is what clients like TightVNC do, which seems like an acceptable workaround, because apparently other servers have the same bad behavior. Using the new version would probably require compiling NoVNC from source.

Well, there is definitely code to enable a cursor. I wonder if it's disabled by default?

Not sure what changed, but there is now a mouse. Works great!

I think you just got lucky. I sometimes see a cursor, sometimes not. If the application is already running and I make the cursor appear, reconnecting later it will be visible, but not from a brand new start. Using build 150.

FYI, in the latest builds using the Standard Client, you can go to Settings -> Advanced and turn on "Show Dot when No Cursor". It will enable a (very tiny) dot, in the same way as a normal VNC client, that will show where the cursor is. Not perfect, but certainly helps.

I was having the same problem. When I click the File menu at the top, my cursor appears, and works from then on. Seems like Xorg needs the focus and then the mouse will display over the app,.

I'm having the same problem, using Chrome, Firefox or Edge on Win 10.

Using Firefox on an Ubuntu 18.04 box shows a normal cursor.

Switching to the TightVNC Viewer on the same Win 10 desktop, I do see the dot for a cursor.
