Hello I'm using Mandriva 2007 on a laptop with a bluetooth chip and I enconter many problems to work correctly bluetooth functionnalities (while this worked perfectly under Mandriva 2006) note version of kdebluetooth installed with this distro is a beta one; when I'm launching the daemon I have no problem: service bluetooth restart ERROR: Module rfcomm is in use [ OK ] ERROR: Module l2cap is in use by hidp,rfcomm Lancement des services Bluetooth : [ OK ] [root@dhcppc1 bluetooth]# When I'm switching on the button to activate the chip I have in the syslog following messages: Mar 18 11:24:12 localhost kernel: atkbd.c: Unknown key pressed (translated set 2, code 0xd7 on isa0060/serio0).
