I've noticed something over the past few days: When I switch from my KDE session to the console using CTL-ALT-F1, sometimes the background of the console (the text positions that DON'T have characters in them) are given the ASCII block character. All spaces and unused positions are fill with this block. Sometimes it's grey, sometimes other colors - but mostly grey.
Also, there has been an instance or two that switching to the console has forced KDM to restart - the only error I get is a that KDE terminated unexpectedly. Any idea what's up? -Jay
