Also, no nvidia driver seems to be available (strangely enough the kernel module is available):
"Error: no alternative found for nvidia
Error: failed to enable the driver"
"Is nvidia available? no"
Can you try installing or re-installing the nvidia driver, please?
If that doesn't solve your problem, can you please reproduce the error and get the output of dmesg, your /var/log/Xorg.0.log, and /var/log/Xorg.0.log.old, please?
