[Bug 1561474] Re: Bluetooth will be disable after resume from suspend on Xenial

[Ubfan]

Ubuntu 18.04 running bluez 5.37-0ubuntu5.1 has fixed the 16.04 problem
of bluetooth not running after a suspend.  My mouse has successfully
reconnected 100+ times.  The USB inputxx is still incrementing at each
resume, so that may not have been related to the problem.

[Bug 1561474] Re: Bluetooth will be disable after resume from suspend on Xenial

[s]

Seeing very similar symptoms on Ubuntu 17.10 running 4.13.0-19-generic or 
4.14.0-041400-generic.
Sometimes, but not every time, BT is not available after resuming from suspend.

>From other data sources, the root cause is a lack of .reset_resume
handler in the BT driver.

A possible interim fix (worked for me) is

sudo modprobe -r btusb
sudo modprobe btusb

This at least gets BT up again.


A possible (but not confirmed) temporary reboot-persistent fix is

sudo vi /etc/modprobe.d/btusb.conf

and add line with:
"options btusb reset=1"

[Bug 1561474] Re: Bluetooth will be disable after resume from suspend on Xenial

[Ubfan]

The bluetooth failure to resume after a suspend seems USB related. The failure 
happens 
about 50% of the time, and when it does, disabling bluetooth and restarting 
fixes
it.
On a Lenovo W520, Ubuntu 16.04, 64 bit, kernel 4.4.0-98-generic, Microsoft 
Sculpt
Comfort BT mouse.

Looking at dmesg|tail on the restoring of BT mouse after sleep and restarting
it, a new USB device is created and used.

Return from sleep, BT indicator greyed, BT says OFF, BT mouse is inactive.
>From the indicator, start BT settings, and from the settings, turn off 
>bluetooth,
(indicator disappears), one line is added to dmesg output:

[37331.845034] usb 1-1.4: USB disconnect, device number 10


>From the settings, turn back on the BT active switch (BT indicator appears):

[Bug 1561474] Re: Bluetooth will be disable after resume from suspend on Xenial

[Kuang-Yu Chang]

It seems the problem for me is the action of 'turn off' bluetooth.

I dual boot with Windows 10. If I chose to 'reboot' (not shutdown) from
windows and boot into ubuntu, bluetooth will start properly and working
fine. The moment I turned off bluetooth it stop working, even reboot
again.

I past below the output for command `dmesg|grep -i blue` under the
situations of working and not working.

>From the dmesg output, it seems different firmware is being loaded for
the two cases (revision 0.1 works while revision 0.0 not work). I
suspect that the bluetooth daemon modify some of the hardware file when
it is turned off. The same for windows 10, I guess it also modifies some
hardware file on restart.

[Bug 1561474] Re: Bluetooth will be disable after resume from suspend on Xenial

[Daniel T.]

Affects me on Lenovo X1 Carbon with Ubuntu 16.04 4.4.0-65-generic. Might
be some kind of race condition when going to sleep. I read somewhere
that hardware does not always notify the kernel (in time) that it goes
to sleep...

Another story is that I shortly the screen with open windows before the
lock screen appears and asks for password.

Re: [Bug 1561474] Re: Bluetooth will be disable after resume from suspend on Xenial

[erintiransom]

Yes, sometimes.

Something else that's curious: sometimes I have a problem with the graphics
after Ubuntu wakes up from sleep, there is a black box around all menus and
anything I point out with the mouse. I found a complicated solution years
ago -this happened in Ubuntu 15.10 too- but recently I found it's easier to
switch to any terminal (CTRL + ALT + F2 / F3 / ... not F7) and go back to
the GUI (CTRL + ALT + F7). This fixes the problem with the graphic card
(NVIDIA something). The curious thing, though, is that it sometimes will
ALSO fix the problem with the bluetooth. Only sometimes. WEIRD.

[erintiransom]

I have to add that in my case, 16,6% to 20% of the times (1 out of 5 or
6 times) the bluetooth is working after recovering from sleep mode,
since the update.

Before the update, it was 1% of the time -I don't have real statistics,
the idea is that it barely ever happened.

Weird.

[Bug 1561474] Re: Bluetooth will be disable after resume from suspend on Xenial

[erintiransom]

Just kidding. It's doing it again.

It find it is a very weird coincidence that it didn't do it, just once,
yesterday morning after restarting from an update the night before that
actually had to do with firmware for a bluetooth adapter.

[Bug 1561474] Re: Bluetooth will be disable after resume from suspend on Xenial

[erintiransom]

I marked my bug #1611188 "Bluetooth doesn't work after recovering
computer from sleeping" as a duplicate of this. Sorry, somehow I missed
this bug that was already open.

Same thing with Dell Latitude E6410 with bluetooth adapter:
430-3659 : Dell Wireless 375 Bluetooth Module, Dell Latitude E

Although this morning I didn't have the problem, which ALWAYS happens,
so I think it might have been fixed by yesterday's update to linux-
firmware 1.157.3:

https://launchpad.net/ubuntu/+source/linux-firmware/1.157.3

linux-firmware (1.157.3) xenial; urgency=medium

  * linux-firmware: Add firmware file for Intel Bluetooth 8265 (LP:
#1599071)

I think it's been solved for some people, at least!

The same bug exists on my Lenovo ThinkPad Edge E320 with Ubuntu 16.04.1.
Newest, upstream kernel (4.7.0-040700-generic) seems resolving it.
