I'm experiencing the same problem (I'm the OP from the link posted in #2) on my T530. However, downgrading ubuntu-drivers-common to 0.2.91.5 didn't work for me, even after reinstalling the nvidia drivers.
It seems as if something keeps changing the alternatives for x86_64-linux-gnu_gl_conf because if I change them, I can modprobe the nvidia driver. I just can't get the update to persist.
Switching to Discrete Graphics in the BIOS is a workaround for me because the nvidia driver can now load and I can use a multiple monitor setup. It's not a fix though and causes other (well-known) problems.
