I'm having a similar problem with my Dell Inspiron 1545 (Intel Mobile Graphics GM45).
It show the login screen and mirror the notebook screen and the external monitor. If I set the mirroring off and maximum resolution to bough screens (notebook screen: 1355x768, external monitor: 1600x900) bougth screens goes black and altough the mouse pointer is still visible, it can't be moved. I get back to Ubuntu 11.10, but can reproduce the bug with the live USB stick version. How can I help to give more information about the bug? Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/912387 Title: [arrandale] Black screen on login regression (oneiric->precise) with external displayport monitor To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/912387/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
