Hi, On my Optimus laptop (with both Intel and Nvidia GPUs), I'm trying to avoid loading the Nvidia drivers on startup (in order to power down the Nvidia card with bbswitch). When I blacklist them in /etc/modprobe.d/, they don't load on boot, but X seems to be loading them, despite the fact that X is using the Intel card. I'm not using an xorg.conf file and there's no mention of nvidia in the Xorg.0.log, but syslog and dmesg show that X is loading the nvidia driver - these lines appear in the logs when I start X:
