[X2Go-User] Losing mouse click ability and keyboard events

[Nicolas Ecarnot]

Hello,

First post, thank you for welcoming me here.
 From an Ubuntu 20.04 client to an Ubuntu 20.04 server, the default 
repository install is working out of the box, all is nice.

But from times to times (random but around 15 min. ), with no obvious 
reasons, I'm losing the ability to click :

- the display is still fine
- the mouse cursor is still drawn
- when moving the cursor, it is reacting to the windows borders, URL 
links, any sensitive parts of the display
- but no mouse button click seems to be sent
- no keyboard stroke seems to be sent either

When killing the client and connecting again, the display is still fine, 
but the same problem remains.
I tried to run the x2go client from a terminal to have a look at what 
could be wrong, but nothing obvious came to my mind.
I tried to have a look at the server's log but I found none.

I don't know if I could run the client and/or the server with additional 
verbosity to try to get more hints?

Does that look like something familiar?

Thank you
