About the brightness, from kernel 2.6.38 you can add to grub the following option: video.use_bios_initial_backlight=0 And remove echo 10 from rc.
If you have time, could you please load the module btusb and check if you observe this intermittent high pitch noise? modprobe -a btusb If it's enabled by default (check lsmod) try to disable the module (modprobe -r btusb) and check if the machine sounds different :-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/613963 Title: Kubuntu on HP Envy 17 - 1010el -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
