I’ll look into it in more detail when I’m back in my lab, but one thing to bear in mind is that TurboVNC isn’t like a regular X server. Because it runs entirely with user-level credentials, it can’t access any physical devices on the server even if it wanted to. Creating and managing input devices occurs within the X.org hardware-dependent code. In the case of TurboVNC, the hardware-dependent code is the TurboVNC Server, so any new input devices have to be created by the TurboVNC Server code. Our remote X Input interface taps into that, allowing you to mirror a physical input device on the client with a virtual input device in the TurboVNC Server session. But those virtual input devices are connected to physical input devices on the client, not on the server. Physical input devices on the server are not accessible by TurboVNC (which, incidentally, is why VirtualGL is needed in order to get GPU-accelerated OpenGL.)
I’ll look at the code you sent and see what makes the most sense in terms of using it with TurboVNC. > On Sep 19, 2021, at 4:17 PM, joa...@verona.se wrote: > > Hello, > > I would like to experiment with synthetic libevents, like what is done > in this post: > > https://unix.stackexchange.com/questions/508612/simulate-graphics-tablet-using-libevent > > What it does is creates a fake event device, sends events with pressure, > so in a pressure sensitive application you can see the effect, whcih is > shown in the post. > > This program works locally on the client machine, but not on the > turbovnc server.
