Comment 15 for bug 1773113

I have what seems to be a similar problem. Have a machine with stock Ubuntu 18.04 clean install. Ran fine with latest recommended proprietary driver for over 2 weeks. Then Friday the 15th June, 2018 it refuses to use the proprietary drivers. The latest Kernel version will not even show the login screen, just hangs in the tty 1. The previous kernel shows the login screen, but it is choppy and will not accept valid login credentials.

Also, noticed that lspci shows that only nvidiafb and nouveau modules are loaded, no drm or nvidi_xxx.

I have purged and installed three different sets of drivers with no success thus far.
