After starting the PC you see the - BIOS-Logo, - blinking cursor, - Screen goes on, - Screen goes off. The only workaround is to switch with CRTL+ALT+F2, then CTRL+ALT+F7. After that everythings normal and i enter my password for the hdd encryption. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1065902 Title: black/blue screen before installer, tty switch fixes it To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-omap4-extras-graphics/+bug/1065902/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
