Bluetooth Mouse: Sleeps too Quickly-Often

Post by hglee » Fri Jun 22, 2018 7:34 pm

With a recent kernel upgrade, my Bluetooth mouse now sleeps too quickly and often, which means there's an annoying idle-lag each time the mouse must re-awaken.

System: Host: Asus FX53VD. Kernel: 4.13.0-45-generic x86_64 (64 bit gcc: 5.4.0).
Desktop: MATE 1.18.0 (Gtk 3.18.9-1ubuntu3.3) Distro: Linux Mint 18.3 Sylvia.

This same problem also appears in a discussion of the Redhat kernel, in this thread...
https://bugzilla.redhat.com/show_bug.cgi?id=570291
"Description of problem: When using a bluetooth mouse, there is a noticeable lag when moving it after leaving it idle for a few seconds. Once moving it tracks OK."

The information in this particular comment seems useful...
https://bugzilla.redhat.com/show_bug.cgi?id=570291#c13

According to that post, an "echo on > level" terminal command should patch the problem, but it doesn't for my system. I found that the "level" file already contained "on". My patch was to increase the value in the "autosuspend" file.

Altogether, I followed these steps, which delays the problem...

Code: Select all

sudo -i
cd `readlink -f /sys/class/bluetooth/hci0`
cd ../../../power/
echo 300 > autosuspend
exit
This isn't a proper solution, as a kernel fix is needed.

BTW, my Bluetooth mouse identifies as a "JETech 0884".
