If you are still having trouble with the new driver, I would suggest using
ports-mgmt/portdowngrade to downgrade the version of the port in the ports tree. This will only revert the ports tree, not the already installed package.
After you have done this you will have to force a rebuild of the port with
portupgrade or
portmaster or:
# cd /usr/ports/x11/nvidia-driver && make deinstall && make reinstall
After that you probably will want to prevent that port from being upgraded until a fix is found. You could add the following line to your
/var/db/sup/refuse file to prevent the port from being updated by
csup:
Code:
ports/x11/nvidia-driver/*
Be sure to reboot after this since you will still have the newer kernel module loaded.
