I have Ubuntu 12.10 on Acer Aspire 4736z and I installed Braid. When I have just turned on the computer, login and then launch Braid right away, it works just fine. But when I have already been using the computer for some other tasks like browsing or typing on Open Office after booting up and then decide to play Braid, the backlight turns off and I cannot turn it back on using the screen brightness control buttons. I have uninstalled and reinstalled Braid but it's the same. Please help me. Thanks.
