Hmmm, I doubt that. Usings NX the client side is not really doing anything X wise. It's the nxagent that calls XineramaQueryScreens(). It asks the client side X server (the real X server) for its Xinerama configuration. We have learned from the previous outputs that Walis had sent that the real X server does not have Xinerama configured. Therefore the agent does not see any Xinerama configuration. (The only possible exception to this would be nxproxy running with LD_PRELOAD of libfakexinerama.so which is not happening here.) Now, in the Laptop scenario you can see via xrandr that nxagent has gotten the Xinerama information somehow. Otherwise it would not have been possible to setup two NX outputs/monitors/heads. The two logfiles are almost the same except the last line where the in the Laptop scenario you can see this line Info: Screen [0] resized to geometry [3840x1080] fullscreen [1]. This line is printed if nxagent has received and processed a sizing event. In the TCE scenario no sizing event was sent to nxagent which - if really true - is probably the TCE window manager's fault. Walid, can you please try pressing CTRL-ALT-F twice in the TCE scenario? What is xrandr showing afterwards? Uli
