Exactly same issue for me described here, but with a dell latitude E5510 Running 12.04LTS, after booting since 3.2.0-32-generic, the laptop display goes black, external displays work correctly. It does NOT occur with 3.2.0-31-generic.
The today upgrade to 3.5 did not solve this issue -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1077064 Title: Laptop LCD goes black after booting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1077064/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
