Actually, my apologies. I rebooted after reinstalled the revised version of bluez and it all works fine now.

Hi, I'm not sure if this is the right place to post this. But basically, I applied the patch that Steve created but the issue appears to persist. Did I apply it properly? Here's what I did: I edited bluez/profiles/input/device.c and then ran './configure', 'make' and 'make install'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1717796 Title: Bluetoothd fills 100% CPU when bluetooth keyboard goes in idle To manage notifications about this bug go to: https://bugs.launchpad.net/bluez/+bug/1717796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Many bluetooth HID keyboard profile devices disconnect on idle to save
power, I have two such devices:
Logitech Y-X5A77 keyboard
Sony PS3 bluetooth remote control
When the device disconnects on idle the g_io_channels get disconnected
bluetoothd[3167]: profiles/input/device.c:ctrl_watch_cb() Device
00:07:61:F6:C9:7D disconnected
bluetoothd[3167]: profiles/input/device.c:intr_watch_cb() Device
00:07:61:F6:C9:7D disconnected
But, something isn't closed properly (possibly g_io_add_watch) since
bluetoothd then spins at 100% CPU in g_main_loop_run() until the device
reconnects, at which point every works normally again until the device
next idles.
This bug has been present for at least 2 years, I'm certain it's much
longer:

Ahhh...
I was already aware that on first connect the HID input device wasn't
created, but I hadn't realised it's part of the same bug.
What's happening is that on initial connect:
dev->sec_watch = g_io_add_watch(idev->intr_io, G_IO_OUT,
encrypt_notify, idev);
creates the notify callback. But it never triggers. On second
connection the callback gets triggered, but the connect code gets run
again so another refcount is added. This means the intr channel never
gets closed which means it's stuck on the last event.

That will prevent the channel getting left dangling, but it doesn't
address the issue of the callback not happening on initial connect,
which is AFAICT what results in that part of the bug for me.
Is it really supposed to be waiting for G_IO_OUT? It seems it only gets
triggered for me when a second connection

[Bug 1717796] Re: Bluetoothd fills 100% CPU when bluetooth keyboard goes in idle
Dear Ubuntu dev Team DON'T MAKE "UPGRADES" WHICH CHANGE PERMISSIONS!!! It is a permission problem with my home folder and pulseaudio. I've had 2 issues: - bluetoothd operating at 100% of one CPU core - no way to connect ANY bt device If happened after one of your "upgrades", so please test it MORE THOROUGHLY next time. Yes, I'm certain it happened after an upgrade cause I made backup 2 days prior to this extremely frustrating issue and no software other than "ubuntu upgrade" was installed in the meantime. After having researched internet twice and having already made my mind to switch to another linux distro if the solution does't come up till the end of the day - I came across this: Run the following command to fix the $HOME directory permissions for the current $USER: sudo chown -R $USER:$USER $HOME/ I used http://www.linuxquestions.org/questions/linux-software-2/problem-with-pulse-audio-834041/ and http://ubuntuforums.org/showthread.php?p=6208727 as sources. The solution for me was to fix the permissions using the following command: sudo chown -R lionel:lionel /home/lionel and then using pavucontrol to unmute the output. The gnome indicator is still greyed but music is back, and that's a good thing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1717796 Title: Bluetoothd fills 100% CPU when bluetooth keyboard goes in idle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-consumption/+bug/1717796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks. Unfortunately it appears bluetoothd is a single-threaded program spinning its g_main_loop without actually doing any heavy work on each iteration. This makes it hard to identify the cause of the problem without running it through a profiler. ** Changed in: bluez (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1717796 Title: Bluetoothd fills 100% CPU when bluetooth keyboard goes in idle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1717796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

We need some stack information to help us determine the cause of the CPU spikes. 1. Download the attached dstack script to your home directory. 2. Log in to a virtual terminal (Ctrl+Alt+F1), and switch back (Ctrl+Alt+F7) 3. When the spike happens, switch to Ctrl+Alt+F1 and run this: sudo -s sh ./dstack bluetoothd >> stacks.txt sh ./dstack bluetoothd >> stacks.txt sh ./dstack bluetoothd >> stacks.txt sh ./dstack bluetoothd >> stacks.txt sh ./dstack bluetoothd >> stacks.txt (yes, five times) 4.
