any news? btw it seems related to the latest patches in .22 kernel release about the i915 backlight. in fact if I blacklist completely the i915 module the bootup is ok..
I tried to pass 'acpi_backlight=video/vendor' and 'i915.enable_backlight=1/0' but without success. note: This laptop is a Dell L702X -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1053269 Title: screen goes black after grub, lights up again when X starts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1053269/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
