The system would freeze up after logging in as soon as I touched the KB or mouse. The cause of the problem, I was told, was the irq conflict between the USB devices and the NVidia card. I recall I emailed Nvidia and complained about their driver and they could not fix the problem. Seems after all these years they are still not fixing the problem. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
