I have the same problem. I upgraded from Hardy to Intrepid RC. Login window appears; but after entering user ID and password, the screen goes blank. I read in Ubuntu Forums that removing compiz and compiz-core will fix this problem which is what I did by entering the system in Terminal mode. I installed all updates ever since. If I install compiz and compiz-core now, the system behaves in the exact same way it did a few days go (screen goes blank after entering user ID and password). So, this issue is not yet addressed in Intrepid final release. I can use my computer now without any Visual Effects. I hope this is not the case forever.
