[I posted this a day or two ago on the Users list but got no replies]. I have a Bluetooth mouse (Sondstrom) which after a fairly short period of inactivity - a minute or two - becomes unresponsive, i.e. it takes a few seconds of jiggling for the cursor to move, whereupon it's fine until it goes to sleep again. As far as I can tell, the mouse itself isn't asleep (the sensor LED is still on) so I assume this is caused by some system setting, but which? I could see the sense if I was on a laptop, but this is a desktop machine and the power management is set to turn off the monitor only after 30 minutes or so. This is F21 under KDE (Plasma-5). The mouse connects via a Broadcom Bluetooth dongle. poc _______________________________________________ kde mailing list kde@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kde New to KDE4? - get help from http://userbase.kde.org
