I have os 13.1 rc1 installed on two machines, both were installed with M3 I think and upgraded to rc1.
Neither now have working Bluetooth, it was working at times previously. I have transferred files to/from my SGS4.
Primary system I use as my Development laptop for Rails 4/Angular dev is a HP EliteBook 8560p the other an i3 eMachines laptop with
a USB Bluetooth dongle, a cambridge one.
I have gone through the btrfs filesystem filling up several times, and eventually worked around it, rc1 actually has a btrfs check that
fixes this issue, and I had to manually configure up snapper to work.
Snapper from yast also does not work anymore, thou should file a separate issue for this one.
snapper list works from command line, just the gui fails to start.
