Similar to issue #295251, brightness control from Fn+up / Fn+down buttons on Samsung nc10 is broken in Ubuntu 10.10. (Was fixed in later 2.8 kernel but seems broken again in 3.0). Pressing Fn+down (brightness down) key causes brightness to reduce to 0%. Pressing Fn+up (brightness up) key causes brightness to increase by one step. Pressing Fn+up again causes brightness to increase to 100%. Sometimes, with no key press at all, brightness seems to toggle up and down at high rate, making operating system unresponsive to key presses until the brightness keys are operated. It would seem some other event is triggering brightness changes. |
