Thanks. After I sent the original message, I was trying different things and after a couple of reboots it now seems to work. I don't think I changed anything though. Perhaps the reboot just cleared things up with the other drivers. I still have the problem with losing the cursor in the console, so I may report that. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
