In order to check the origin of the high pitch noise I opened the pc. The noise comes from wlan/bluetooth module.
My hardware is: Wi-Fi Broadcom 43224AG 802.11 a/b/g/draft-n and HP Integrated Module with Bluetooth 2.1 Wireless Technology. On ubuntu I'm using the default bcmwl module. So these two problems still: + High pitch intermittent noise from wlan module. + Screen brightness is set to minimum after ubuntu boot splashscreen, then it returns to normal after logon. + Mouse special mouvents (like 2 fingers) doesn't work, mouse lock doesn't work. -- Kubuntu on HP Envy 17 - 1010el https://bugs.launchpad.net/bugs/613963 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
