Public bug reported:
Since upgrading from Ubuntu 18.04 Bionic to Ubuntu 18.10 Cosmic, I've
started seeing issues with getting into Xorg.
My config:
01:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce GTS 250]
(rev a2) (prog-if 00 [VGA controller])
Subsystem: Gigabyte Technology Co., Ltd G92 [GeForce GTS 250]
System Information
Manufacturer: Gigabyte Technology Co., Ltd.
Product Name: P55A-UD4
Ubuntu 18.04 Cosmic w/nvidia-340 proprietary drivers.
This appears to be, in part, due to a newer kernel with stricter
permissions around kernel access.
This seems to have been fixed in Debian:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=899998
... by backporting the fix from nvidia-390:
https://bugzilla.redhat.com/show_bug.cgi?id=1570493
https://bugzilla.redhat.com/attachment.cgi?id=1425704
Could this patch also be applied to nvidia-340 for Ubuntu?
Error I'm seeing on my own system (from dmesg):

Unsure if related, but now when my computer boots up and gdm runs, I
have to press Ctrl+Alt+F2 and then Ctrl+Alt+F1 to actually get GDM login
screen to show.. Otherwise my computer sits in text mode. Set nomodeset
and GRUB_TERMINAL=console or otherwise input control locks up when gdm
launches.
