In my case it is definitely kernel issue / Asus Aspire Intel GMA 4500M I worked around it by adding acpi_backlight=vendor to the kernel command line in grub.cfg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/739313 Title: laptop screen very dimly lit -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Since it occurs before GDM, after grub starts loading the kernel, then it looks like kernel lvds brightness control is messed up. Possibly ACPI related. ** Package changed: xserver-xorg-video-intel (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/739313 Title: laptop screen very dimly lit -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Issue is not consistent and exists also in LiveCD. This happens before GDM/LiveSession, even without splash. Brightness level goes down during boot and maximum available level becomes about 1/4 of the normal one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/739313 Title: laptop screen very dimly lit -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
