It is a X2Go patch.

It is wrong solution. Only (nx|x2go)agent should be linked against nx-libs. X-clients should be linked against system X libraries. Exception is libXinerama. Against this library should be linked both - agent and client. But in case of agent libXinerama should use libXext and libX11 from nx-libs and in case of clients it should use the same libraries from system. For this reasons we exporting LD_LIBRARY_PATH=/usr/lib/nx/X11 by start of agent and LD_LIBRARY_PATH=/usr/lib/nx/X11/Xinerama (*but not /usr/lib/nx/X11*) by start of desktop environment. >> As solution, I can suggest: >> >> leave libNX_Xinerama* under /usr/lib/nx/X11/ >> make symbolic links /usr/lib/nx/X11/libNX_Xinerama* -> >> /usr/lib/nx/X11/Xinerama/libXinerama* >> >> link system libraries libX11 and libXext into /usr/lib/nx/X11/Xinerama >> /usr/lib/libX11* -> /usr/lib/nx/X11/Xinerama/libNX_X11* >> /usr/lib/libXext* -> /usr/lib/nx/X11/Xinerama/libNX_Xext* > > You cannot touch my xorg-x11 libs. I don't want to touch your xorg-x11 libs, I just want to make links from them to /usr/lib/nx/X11/Xinerama/ : ln -s /usr/lib/libX11.so.6 /usr/lib/nx/X11/Xinerama/libNX_X11.so.6 ln -s /usr/lib/libXext.so.6 /usr/lib/nx/X11/Xinerama/libNX_Xext.so.6 libXinerama should use a system libX11 and libXext. But because of your patch now it linked against libNX_X11 and libNX_Xext. This is why we should create such symbolic links. > _______________________________________________ > X2Go-Dev mailing list > X2Go-Dev@lists.berlios.de > https://lists.berlios.de/mailman/listinfo/x2go-dev regards, Alex -- Oleksandr Shneyder Dipl.
