Thanks for the reply matey... I did the following 1) run lshal -m in xterm 2) then connect your bluetooth headset(xterm should register sth at this point) 3)then again disconnect(optional) nothing other than battery voltage,battery reporting current and remaining time. However, I do see the yellow bar msg on the top of the screen "Connected to Invisio G5". The headset works, no doubt Regd. the proximity, I guess i wasnt clear.. What i meant is that my settings is set such that proximity sensors wont be deactivated, sliding out keyboard. I mean this is an additional info, if it helps debugging the above mentioned issue. Also to add, i tried enabling and disabling visibility. No luck, the same battery stuff. pleasz help!!
