XIinputExtension XI2 applications won't work

[camiloaa]

A number of GNOME applications were updated to use XI2, and as a result stopped working with libnx/x2go.

For example, gedit tries to set XInputExtension.X_XIGetClientPointer and causes the next error:

The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 1432 error_code 1 request_code 131 (XInputExtension) minor_code 45)

Oh well... The lack of Xinput2 is also causing KDE5 to crash during startup. So this is something we need to look at rather sooner than later.

Thanks for giving feedback on recent changes in GNOME apps.

It makes me feel bad about KDE and Gnome quality if they crash instead of reporting an error...

Exactly what I thought, the first time I saw Plasma5 crash in nxagent.

I just took a quick look at this today. The XInput2 extension requires forward-porting of the Xserver code at least to X.org v1.7. This will be impossible for nx-libs 3.6.x, unfortunately.

However, there might be a way of providing some xistubs.c code that fake-handles the most important XI2 requests and either drops them or converts them to XI1 requests. Not sure.

Should we consider this solved? Most broken apps are running again.

Let's keep it open, I'd say. We don't yet have XI2 extension support in nx-libs and I'd say we leave this open, until this is resolved.
