Hello! I have this same laptop Dell C640, running intrepid with ati driver. Graphic card is ati radeon mobile 7500
I've noticed that the Fn key function for brightness and contrast work fine while in grub or while ubuntu is loading. Then it has no effect after gdm started and in gnome. So you should test the keys while ubuntu is loading. All other function using Fn are working fine : volume, mute, eject and so on. I will try kde to see if it's the same. grillon -- Fn+Up/Down does not change screen brightness on Dell Latitude C640 https://bugs.launchpad.net/bugs/309973 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
