Status changed to 'Confirmed' because the bug affects multiple users.

I am also getting the login loop with nvidia-304.134

Sorry I mis read the report.

I am getting the login loop with nvidea 304 not 340

[Sébastien Lamy (lamyseba-b)]

On ubuntu 16.04-2, This bug doesn't affect me with nvidia 304.134, but I had other problems with this 304.134 driver, and I tried to use nvidia 304.135 from the ppa:graphics-drivers/ppa.
With the 304.135 installed, I got stuck in the login loop.
Same thing when trying the 331 drivers
