Dear Jonathan, Thanks again for your interest and patience. > Here's how I would suggest blacklisting the drivers: > echo blacklist nouveau >/etc/modprobe.d/ls-blacklist-gpu-drivers.conf > echo blacklist nvidia >>/etc/modprobe.d/ls-blacklist-gpu-drivers.conf > Then choose "recovery mode" from the boot menu so X doesn't > automatically start.

If I don't blacklist nouveau, the screen becomes dark gray and the computer seems not to respond, so I had to reboot into a live CD to blacklist both drivers, as you suggest, in order to get a working console. I checked with lsmod that neither driver was installed. Furthermore, I didn't get the usual 'nvidia driver taints kernel' message on startup. Nevertheless, when X was started (after I logged off of single user mode), the nvidia startup screen was displayed and the nvidia driver was loaded. $ lsmod|grep nvidia nvidia 10183049 43 i2c_core 19116 2 i2c_i801,nvidia Thus, I guess that the blacklist mechanism doesn't inhibit X from loading nvidia.
I found I had another file /etc/modprobe.d/nvidia-kernel-common.conf with contents: alias char-major-195* nvidia options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=44 NVreg_DeviceFileMode=0660 # To enable FastWrites and Sidebus addressing, uncomment these lines # options nvidia NVreg_EnableAGPSBA=1 # options nvidia NVreg_EnableAGPFW=1 # see #580894 blacklist nouveau I renamed it to /etc/modprobe.d/nvidia-kernel-common.confold to get it out of the way, but I didn't notice any change. I don't know if it is better to keep that file as it was or to remove it. I checked the /dev directory: $ ls -l /dev/|grep nvidia crw-rw-rw-+ 1 root root 195, 0 Oct 9 19:57 nvidia0 crw-rw-rw-+ 1 root root 195, 255 Oct 9 19:57 nvidiactl Also, I don't know if I should keep my current configuration (blacklisting nvidia and nouveau) or if I should return to the previous one. Anyway, my problem (the laptop fails to shut off) seems to have been solved with the last nvidia upgrade of debian/testing. I still have some other problems like an occasional black screen after suspend/resume. As you see, there are many things I don't understand, but I'm very grateful for your advice.
