Public bug reported: It is a Lenovo G50-45 laptop with AMD/ATI Radeon APU A4-6000 with R2 Graphics.
When I boot up Ubuntu 14.04.1 64 bit using fglrx (or fglrx-updates) 2:13.350.1-0ubuntu2, the screen gets very dim at LightDM and remains dim in Ubuntu desktop until I press one of the two brightness keys or change brightness in System Settings. Even though the screen is dim, the brightness slider in System Settings or the brightness on-screen display shows that brightness is set at the maximum. It does not matter whether I increase or decrease brightness with the function keys or the slider in System Settings, the screen will immediately brighten up after touching the brightness keys or the System Settings slider. No improvement with fglrx 14.100-0ubuntu1 built with ubuntu-amd- catalyst-install 3.9 either. ** Affects: fglrx-installer (Ubuntu) Importance: Undecided Status: New ** Package changed: webapps-applications (Ubuntu) => fglrx-installer (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1360218 Title: Dim screen until brightness key pressed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1360218/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
