Usings NX the client side is not really doing=20 anything X wise. It's the nxagent that calls XineramaQueryScreens().=20 It asks the client side X server (the real X server) for its Xinerama=20 configuration. We have learned from the previous outputs that Walis=20 had sent that the real X server does not have Xinerama configured.=20 Therefore the agent does not see any Xinerama configuration. (The only=20 possible exception to this would be nxproxy running with LD_PRELOAD of=20 libfakexinerama.so which is not happening here.)=20 Now, in the Laptop scenario you can see via xrandr that nxagent has=20 gotten the Xinerama information somehow. Otherwise it would not have=20 been possible to setup two NX outputs/monitors/heads.=20 The two logfiles are almost the same except the last line where the in=20 the Laptop scenario you can see this line=20 Info: Screen [0] resized to geometry [3840x1080] fullscreen [1].=20 This line is printed if nxagent has received and processed a sizing=20 event.
