I upgraded from 16.04 to 18.04.1 and all seemed to go OK. But when I rebooted, the system hangs.
Early in the boot process, I get the error message: Error no video mode activated
The last lines shown are:

I can ping the system when it's hung, but I can't ssh into it.
I can boot into recovery mode, bring up a root shell, and see all my files.
When I resume normal boot from recovery mode, I get a flickering error message:
[ 256.522705] do_IRQ: 1.36 No irq handler for vector
This continues indefinitely.
The specs on my video card are:
EVGA GeForce GTX 660Ti PCI-E 3.0 2048MB 2 DVI, 1 HDMI 1.4, 1 DisplayPort;
2048MB GDDR5 Memory (192 bit);
Base Clock: 915 MHz;
Memory Bandwidth: 144.192 GB/sec Supports NVIDIA CUDA: 1344 CUDA Cores
Is this problem related to the 18.04.1 video driver? How do I fix it?
