I've been able to replace the nouveau driver with an nvidia one by (1) adding rdblacklist=nouveau to the active kernel entry in grub.conf and (2) yum install kmod-nvidia-PAE. The last little "Gotcha!" for his problem was the need to run nvidia-settings as root (rather than from the Applications --> System Tools --> nvidia Display Settings menu): sudo nvidia-settings Otherwise I was unable to permanently activate the second monitor by saving the X configuration file.\ Thanks for the help with this! -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
