  4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and
  16.04)

Status in linux package in Ubuntu:
  Confirmed
Status in nvidia-graphics-drivers-384 package in Ubuntu:
  Confirmed
Status in xorg package in Ubuntu:
  Confirmed

Bug description:
  Running fine with nvidia-384 until this kernel update came along.
  When booted into the new kernel, got super low resolution and nvidia-
  settings was missing most of its functionality - could not change
  resolution.

  Rebooted into 4.4.0-112 kernel and all was well.

  The root cause of the problem has been found to be installing the -116
  kernel without a sufficiently updated version of gcc.  In my case, my
  system received the gcc update AFTER the kernel update.

  Uninstalling the -116 kernel and reinstalling it with the updated
  version of gcc solved the problem for me.

Same issue with HP Pavilion f-105ng and Ubuntu 14.10 64bit.

Title:
  Bluetooth BCM43142A0 doesn’t work

Status in “bluez” package in Ubuntu:
  Confirmed

Bug description:
  I’ve installed ubuntu 14.04 and my computer’s builtin bluetooth
  (computer is an Asus x550ln) doesn’t work at all. Bluetooth is not
  displayed in the menu bar, if I open the bluetooth UI and switch on,
  nothing happens and the result of “hcitool dev” is empty.

  I have tried to install the windows driver with ndiswrapper, and the
  bluetooth device seems to be detected as an usb bluetooth device but
  still not working. I then add the device to the bluetooth usb device
  and was able to activate bluetooth in the UI but it does not detect
  any other devices (I’ve tested with a smartphone).

  The driver I have installed can be found in asus page =>
  http://www.asus.com/fr/Notebooks_Ultrabooks/X550LN/HelpDesk_Download/
  Select Windows OS, then “bluetooth” section, take the Broadcom driver
  (should be the first one).

  If you extract this archive, you will find a file named “bcbtums-
  win8x64-brcm.inf” which I installed using the following command:

  ndiswrapper -i bcbtums-win8x64-brcm.inf

  Then, the result of “ndiswrapper -l” is:

  bcbtums-win8x64-brcm : driver installed
device (04CA:2006) present

  in usb-devices, I find a device which was not present before
  installation (I might have activated btusb before on this paste):

  T:  Bus=02 Lev=01 Prnt=01 Port=05 Cnt=02 Dev#=  3 Spd=12  MxCh= 0
  D:  Ver= 2.00 Cls=ff(vend.) Sub=01 Prot=01 MxPS=64 #Cfgs=  1

  I:  If#= 3 Alt= 0 #EPs= 0 Cls=fe(app. ) Sub=01 Prot=01 Driver=(none)

  then, “echo "04ca 2006" > /sys/bus/usb/drivers/btusb/new_id”, and I
  can switch usb on, but no device will be detected and I’ve found this
  in the dmesg:

  [2200.843126] Bluetooth: hci0 command 0x1003 tx timeout

  which looks pretty much like a “bluetooth not working” message which I
  don’t understand in details.

[Kernel-packages] [Bug 1416892] [NEW] Bad WiFi connection and no working Bluetooth with BCM43142

2015-02-01 Thread Silvano

Two different problems with the same device:

1. Bluetooth doesn't work at all. The device is detected properly and
the driver is apparently installed, but no connection can be
established.

2. WiFi connection is half so strong as with other devices or the same
computer with Windows. It also gets lost if farther away than 3 meters
without walls inbetween from the router.

Title:
  [Dell G15 5515] Unable to change screen brightness in ubuntu desktop

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have Dell G15 5515 Ryzen edition. It has Nvidia 3050 graphics.

  In /sys/class/backlight directory, there are two directories
  amdgpu_bl0 and nvidia_wmi_ec_backlight.

  When I change the screen brightness via slider then it changes the
  brightness value of nvidia_wmi_ec_backlight but it doesn't work. When
  I manually changed the value of amdgpu_bl0 brightness file then my
  screen brightness changed.

  My BIOS is updated to the latest version and I have NVIDIA Driver with 
version 510.73.05.
