Today I installed from the 5/4/11 rolling release. Installed and configured with nv driver, everything worked fine. Tried to install the nvidia driver using controlbox/hardware. The driver seemed to install fine, checked slim.conf, driver not listed, edited file to load driver. Rebooted, got blank screen. Could not change to a console that I could see.
logged in via ssh, ran tazx, tried to change back to nv driver. Rebooted. Same problem. Ssh again, lsmod shows nouveau driver still loading even though tazpkg says it is not installed. Add nouveau to /etc/modprobe.d/blacklist. Reboot. System boots, but will not autologin anymore. I have to login and run startx, slim doesn't run at all.
How do I restore my system to the condition it was in prior to loading the nvidia drivers? How do I remove the nouveau driver completely and prevent it from loading without using the blacklist, as it was before I tried installing nvidia? What other changes did the failed attempt to install the nvidia driver make and why doesn't reinstalling the correct driver work anymore?
