This did not make a difference. I still experience the hang. I had only tried to start X with DRI disabled once. The time I tried it, it worked with the above mentioned interrupt problem. It seems that I got lucky that time. I reattempted to run with DRI disabled, and hung the machine three times in a row. I have run out of time for the moment and will try a few more things tonight. -- Norbert Papke. npapke@acm.org
