Having the same problem here with Ubuntu Natty and Unity Enable, My setup is the following PC with two graphics card,
ATI HD 6950 ATI HD 4670 Both graphics are properly working monitors are detected and configurable, but when Xinerama is enabled then unity is not booting and X crashes, the only way to login is restarting gdm from a terminal and setting as session ubuntu with no effects. it seems that unity and compiz is not properly working in multiple monitors environment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/773065 Title: unity does not start on multi graphic card system -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
