Hi, I have a macbookpro 7,1 with some hardware problem, I think, that make system freeze if screen goes off, or sometimes I need to close lid wait and reopen to make the screen turn on again.
The system is quite usable but I can't switch user from gnome session since screen remain dark after I give the command to switch user from gui; even in this case closing the lid wait and reopen seems to work at least when blindly typing I have pressed esc button and return to the current user (so system is not freezed).
Can I avoid that blank screen when switch user (I think this problem is related to hardware problem I had even with osx)?
To be clear with screen blanking I mean let's say no signal like if on external monitor I unplug the VGA cable.
Any suggestion?
Thanks
