Comment 16 for bug 1065380

to quequotion:

I already switched to blueman before I used "Disable=Media". Could connect for the first
time, but never later. As I wrote, adding "Disable=Media" did the job for me.

Later I googled ' linux bluez "Disable=Media" ' and I found plethora of recommendations
for addind "Enable=Socket" and "Disable=Media" if using bluez >=4.96 (and that is our case).

bluez 5.0 and newer require new config arguments again, because of programming changes
and code tidying, but this doesn't affect me yet.

Just few references:

For me the case is closed with this workaround and using blueman. I just hope in new
versions of ubuntu/mint they don't introduce new bluetooth bugs or misconfigurated
config files.
