Public bug reported:
Newly installed Ubuntu 19.04 system. AMD Ryzen 3700X. NVIDIA GeForce RTX
2060.
When the system is left for a while and the screen goes to sleep, then
sometimes but not always, upon return there is no reaction to keyboard and
mouse. Most likely the system is still running fine, but the only thing one can
do is reboot. Afterwards, /var/log/kern.log shows lines like
Sep 15 21:50:50 if kernel: [35590.756691] nouveau 0000:07:00.0: DRM: core
notifier timeout
