I have laptop dell inspiron 7577 with GeForce GTX 1050.
Yesterday (18.11.2020) I got updates which include Kernel, nvidia driver etc.
And after that updates I get black screen on laptop’s screen after sleep (Monitor connected via HDMI works).
Before updates laptop’s screen after sleep works fine.
GPU driver: 455.45.01
P.S. Also I’ve made use GeForce by default with this article: archivedforummanjaro.org/t/howto-set-up-prime-output-offload-with-nvidia-proprietary-driver/40225
Update: Try to use Kernel 5.8.18-1-MANJARO and after sleep laptop’s screen works
