Problem solved! When running sudo, the environment variable LD_LIBRARY_PATH is not transferred. But LD_LIBRARY_PATH points to /usr/lib. Without this hint, the libraries were first searched within /usr/local/lib. Within /usr/local/lib were very old libX11* files from 2008-02-24. This old libX11.so.6 needed the libxcb-xlib.so.0, which could not be found. I deleted all the files within /usr/local/lib (there were only libX11* files in it). Because /usr/local/lib is empty, the library search continues to search within /usr/lib, where the new libX11.so.6 is found. I dont know what copied those old libX11* files to /usr/local/lib. I didn't. My system does now function fine again without any errors. :) Horray! -- libxcb crash after upgrade 9.04 https://bugs.launchpad.net/bugs/367068 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
