[Kernel-packages] [Bug 1603715] Re: bluetooth unavailable after rfkill hard (or soft) unblocking and after suspend/resume

2016-11-25 Thread Eric Ding 
I'm experiencing a similar issue on Thinkpad x220 running Linux Mint 18
(based on Ubuntu 16.04) with kernel 4.4.0-21.  In my case, rfkill
unblock needs to be called twice in order to fully enable (and soft
unblock) bluetooth:

# rfkill block bluetooth
# rfkill list bluetooth
0: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: yes
Hard blocked: no
# rfkill unblock bluetooth
# rfkill list bluetooth
0: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
5: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no

(At this stage, Bluetooth appears to be on in the Mint Bluetooth
configuration dialog but can't see any devices).

# rfkill unblock bluetooth
# rfkill list bluetooth
0: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
5: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

(Now Bluetooth works fully as expected).

  bluetooth unavailable after rfkill hard (or soft) unblocking and after

Status in bluez package in Ubuntu:
  Confirmed

Bug description:
  DELL Latitude E5510 has a hardware switch to disable and enable
  bluetooth and wifi devices ("hard blocking" in terms of rfkill). In
  terms of wifi, this works great: After hard unblocking, the device
  resumes back to normal operation without any manual intervention. That
  was also working with bluetooth as of ubuntu 14.04, kernel 4.2.

  In ubuntu 16.04, kernel 4.4.0-31-generic, together with systemd, this
  is not working any more:

  After hard blocking and unblocking

  - bluetooth is not working at all
  - the applet-indicator remains gray
  - bluetooth cannot be enabled with the applet-indicator (see 
https://storage6.static.itmages.com/i/16/0717/h_1468721829_7715160_83cd33bfba.png).
 Applet-indicator remains gray
  - rfkill list tells me that the kernel knows about the hard unblocking (turns 
from "yes" to "no"):
  rfkill list bluetooth
  2: dell-bluetooth: Bluetooth
   Soft blocked: no
   Hard blocked: no
  8: hci0: Bluetooth
   Soft blocked: no
   Hard blocked: no

  The device is a
  sudo lsusb
  Bus 002 Device 010: ID 413c:8187 Dell Computer Corp. DW375 Bluetooth Module

  Workaround: After a

  sudo service bluetooth restart

  the bluetooth device turns back to normal operation and the applet-
  indicator turns from gray to black (available).

  Suggested fix: Make the workaround obsolete.

[Kernel-packages] [Bug 1017072] Re: 046d:08c1 Regression: Quickcam Fusion doesn't work after first time

2015-09-02 Thread Eric Ding 
That fix was from three hours ago, and made it into mainline 3.6, I
believe. I've long since switched computers and haven't tested it
recently, but I would assume it has long since made it into Ubuntu's
releases.

  046d:08c1 Regression: Quickcam Fusion doesn't work after first time

Bug description:
  The first time I plug in this webcam, it seems to work ok (e.g., in
  guvcview). If I turn off the webcam and then turn it on again, all I
  see is a noisy screen with lots of multicolored horizontal lines (see
  attached; colors change in response to waving my hand in front of
  webcam lens, so I know it's still receiving/processing video from
  camera). Sometimes, it works the second time, but after a few more
  times, I see the video with just noise again.

  I see this problem after upgrading from Maverick straight to Precise.
  This is reminiscent of bug 865131, which expired on 2012-05-30. I've
  tested with mainline kernel 3.4 as well, with similar results.

  046d:08c1 Logitech, Inc. QuickCam Fusion

  WORKAROUND: If I unplug the webcam and then plug it back in, then the
  video shows up again -- at least for one time.
